This review of Tecnigas pipes and the dyno curves made me very interested in the TREK.
http://www.pedparts.co.uk/blog/tecnigas-exhaust (http://www.pedparts.co.uk/blog/tecnigas-exhaust)
RacingplanetUSA was the only place I found in the states that carried it and their price is $175 plus shipping.

Found it on ebay from Germany today for $110 US plus $33 shipping so pulled the trigger. I also saw it from an Italian dealer that would have been about $165 total.
Anyway, I'm super excited to give it a workout and report back. Looks like it has a pretty wide power band with peak power around 8500 RPM which should be really good.
I'm collecting stats now on my scooter (RPM, GPS speed, etc.) I'll report back once I have it installed.

Should be good pipe, will be watching for your reports. Cheers

Got my tach today. Riding full throttle up slight incline my revs are just below 7300. Only thing not stock are 6 gram rollers I installed so I could go up hills better.

racing planet USA has almost nothing in US warehouse I garuntee you will have to wait for it shipped from europe. I looked at places for Tecnigas and the best place is Scooter Attack in germany I got my NextR chrome from them and paid just 127 shipped. It took two weeks t get here but the money I saved made it worthwhile.

That's a good price, I bought 2 Tecnigas Next-R from RacingPlanet for $20 or so more, waited long time to come in. Nice to know about ScooterAttack. One thing, US$ is high compared to Euro, so anything from Europe is on sale right now. Cheers

I saw on 49ccproboards you're getting CHT to test before installing your new pipe. Very good idea, wish I had done that, would have baseline for Tecnigas pipe and BBK. I often wish I knew how hot my OEM People 50 2T ran? I ran it WOT all the time with no problems.

I think my scooter is running lean the way it is and want to get a baseline. Was overheating and dying last summer. Pipe is on the boat and I have another week or so to see where I'm at before installing it

Noticed the front tire didn't feel right yesterday so checked air in the tires. They were both below 20 psi. Aired them up and the scooter is 3 mph faster. Cheap speed.

Now I have to show some patience. I want to clean the carb, put it back on and see how it runs before I put the pipe on and rejet it. It's run a little lean ever since I bought it and I want the before and after comparisons to be fair.
Oh and I want to get my Arduino thermocouple working and do head temps too.

Pipe looks good, good price, and reasonable shipping. An easy bolt on mod! Looking forward to how it runs.
I am not familiar with Arduino thermocouple?, I guess didn't go with TrailTech TTO.

Here's the Arduino. It's a diy microcontroller. In the pic, you can see the spark plug adapter. The little chip connected to the red bread board is a thermocouple amplifier. It works now with output to my computer monitor. I need to get it to send to an led display so I can take it with me on the scooter.

Looks pretty nice. The bracket is just thin stamped steel. Fit fine except one of the supplied bolts wasn't long enough so I'll have to get a longer one.
Much lighter than the 13.6 pound OEM exhaust. Forgot to weigh it before I put it on but I read online that it weighs 7.7 pounds.
Sounds pretty quiet. Didn't have time to rejet the carb yet so haven't ridden it.

Well that was disappointing. I cleaned and rejetted the carb. Went up to a 95 main. Took it for a ride and I can't tell any performance difference.
It's supposed to make max power around 8500 rpm, but even on a long straight it's not getting above 7500.
I have 6 gram weights in the variator which tunes it to about 7200 rpm, so I'll probably have to go to 5 gram weights.
Any thoughts?

Not sure what's going on, maybe your carb is smaller than mine, I don't know. I think I was running 7 to 7.5g sliders in mine, worked great, but I was running 108 main jet. Don't know what you weigh, but I am approx 175 to 180#'s. Also, I was running Malossi variator, which seems to help keep revs up, compared to OEM.
I looked at the linked comparison chart, and until you get past 7500 revs, you will have no improvement. Bigger carb, better pipe is all about making more revs.
Try the lighter rollers, I tried 5g in mine once and it rev'd to the moon, should get you to the powerband. Let us know, good luck. Cheers
-
I had over jetted it. Stock People is supposed to have 82 main jet so I bought a 95 and 98 thinking one would be close.
When I took out the main, it was a 70. Very small but I am at 5000 feet here in Denver. Even so it had been acting lean at times. I did pull the plug before I started and it looked almost perfect for a plug with 1000 miles on it.
Since I didn't have a jet between 70 and 95, I used torch top cleaners to make an approximately 89 jet. It ran better, now seems a tiny bit lean.
Variator weights are keeping the ramp up to about 7300 or less rpm. Now it will keep creeping up in speed and when it hits around 7500, it really gets going.
Before the pipe on the flat, I could hit about 42 on the speedometer which is probably about 38 mph. Now it will go beyond 50 indicated. I don't know how much beyond because I ran out of road.
I'll go down to the 5 gram rollers and go up just a bit richer on the jet and see how it does.

So, you're going past 50mph/ 80kph on the speedo? At that speed, my People 50 2T is turning approx 9000revs with BBK. Unfortunately, with 49cc I didn't have a tach on it, so don't know what revs were?
I think you are going in the right direction. One consequence of pipe that makes more HP, may be a little more trouble to tune.
-
Yeah, at 50 I was above 9000 rpm. Even downhill, before the pipe, it never went past 7700

You will amazed how it runs if/ when you get your CVT tuned. Imagine how it will run when scooter starts from dead stop at around 8000 revs and stays there until it reaches approx 45mph. Then revs continue to climb because CVT is in highest gear and scooter continues to gain speed. With the Trek pipe, I think you should be able to turn 11000 revs plus with tailwind/ downslope, and that should be approx 60mph.
Problem is CVT costs $'s. I have approx $200 in my CVT: $70 Malossi variator, $20 Dr Pulley sliders, $95 Malossi torque driver, $18 Malossi green torque spring, plus maybe another $200 plus for rollers/ sliders, torque springs, fly springs I bought to test.
That's the way my Super 9 LC runs. I really don't think I need BBK on it, it runs so well. Has very good acceleration (less than People 50 2T with BBK the king of acceleration to 50mph) and great top speed. People 50 2T is different animal and can use BBK IMO. Cheers

I hear you about the $$$. I just spent $50 on new rollers, torsion controller, and purple spring. That's on top of the $155 for the exhaust. $25 for jets, etc.
Based on how it feels when it gets in the power zone, I'm going to be very happy I spent that much money. The scooter only has 1000 miles on it so should last me a long time.
One thing that I'm still wondering about is the carb size. The scoot has a 16mm carb which seems pretty little. Maybe that's all it needs for 50cc.
I've been trying to find out what size carb the older People came with. Up to about 2005, they were much faster. I know the exhaust was a big factor in newer scooters being slower, but I wonder what size carb the older scooters had. Seems like mine with a performance exhaust is only going to be about the same speed as an older stock one. Of course, I sometimes forget I lose about 20% of my power being at 5300 feet elevation. Maybe that's the difference.
-
BTW, it wasn't too lean. Before I started the project, I drilled two 3/8ths inch holes in the air filter housing to act as tuning ports and let in more air. Since I thought it was running lean, I just covered up the holes and tested it again. It ran much worse, so I'm not too lean after all. May still be a tad rich or may just need to adjust the needle as someone else pointed out. Once I get it jetted right, I can open and close the holes as needed for winter/summer riding.
I'm not going to do any more tuning of the carb until I install the 5 gram rollers and get it operating in the correct rpm range. Hope the rollers get here by the weekend.
-
I don't have experience with scooters except here locally, but you being at 5000 ft, compared with my less than 1000 has to make some difference.
Next time you have your carb disassembled, measure the diameter of the barrel. My People 50 2T OEM Keihin PB16 carb barrel measures approx 17mm, my Malossi Dellorto 19mm carb barrel measures approx 21mm, and looks 2X's bigger than the OEM Keihin PB16 carb barrel.
I think you probably have the same carb as my 05 People, but would be interesting to compare. I think the main diff between years is the pipe, but I don't know.
I really like my People and go back and forth between liking it best or not compared to my Super 9. Mine has over 6000 miles/ 10000 kilometers and seems in really good shape, although I recently stripped out one of the CVT cover bolt holes (should be easy heli-coil fix).
Another good mod is to install better tires. I installed set Heidenau K63 on mine and is big improvement of OEM tires in ride and handling. Cheers
-
Man 50mph at 9K rpm thats nice is that GPS verified? The People must have same gears as Super 9 to go with them tall tires lol cuz my Like 50 will BBK and pipe and all my goodies hits 50 at around 9300RPM and 60 downhill at 9900rpm. . .still haven't got it over 10K rpm but I'm not trying to either lol.
-
pace, no gps, just guessing lols. I do think Super 9 has taller gears, seems to turn less revs for similar speed. Glad your Like BBK is still running well. Too bad oil pump cable didn't break while still in warranty. That's really a bummer, could happen to anyone.
-
I leaned it out a little by opening up the air box a little more and it runs pretty good once it's warmed up for a couple of minutes.
So much more fun with the extra power. Eager for the 5 gram rollers to get here so I can run it in it's power band. Right now it's revving between 7200 and 7400 while it's accelerating. Needs to be at 8500-9000.
Much quicker than stock already. Glad I did this.

I put in the 5 gram rollers and now the variator is tuned to about 8150 rpm. I think adding the torsion controller will get me to the 8400 mark. It preloads the spring by 5 mm and that will probably do it. Probably don't need the purple spring.
We'll see.
One thing is clear is that I don't have the low speed jet right. I can't get it to start and run when it's cold. Even with the air screw all the way rich, it still needs to be manually choked (hand covering the air snorkel) to keep it running.
It's stays running when it's warm, but sputters when I first get on the throttle.
-
I think you are right about the torsion control making the torsion spring a little stiffer. I have installed these and taken them out and don't recall any noticible difference, but I wasn't specifically testing for that part. However, I think the Malossi Purple spring is actually less stiff than the OEM spring, if you install it your variator revs will actually go down for the same weight rollers. The Malossi description is missleading, makes it seen like the springs are additional stiffness, but are not, for example: purple is 82% as stiff as the OEM.
I like to run them because a less stiff torque spring takes less HP to run CVT. You install a stiffer torque spring if belt is slipping. I like to run the Green torque spring 60% with my 49cc Super 9 LC and have never experience belt slip. Cheers

Had some time this morning to get the main jet setting right. I'm at an 89 main up from the 70 that was in there. Keep in mind that I'm at 5300 feet altitude so not as big a jet as at sea level. I opened up the stock airbox quite a bit from stock. The stock box has a 11/16 inch snorkel feeding into it. I've added five 1/2 inch holes to get the air fuel mix right with the 89 jet. That's almost 4 times the size of the openings.
So I know nobody really cares about the jetting. You just want to know the results, right? Before the pipe I was maxing out on the flat at 42 mph per the speedometer. Now I'm at 52 - 53 mph per the speedo. Don't know what that is per GPS, but that's a big increase. Over a 10 mph increase.
It's also a lot better on the hills. There is a long, maybe half mile hill that I have to ride up to get to my house and before the pipe, I'd gradually slow down until I was going only 25 up it. This morning, I went up it and slowed only to 35. So I've solved my two biggest complaints with the pipe. Now I can get up that street and stay over the 30 mph speed limit and I can go on the couple of 45 mph roads that get me across town without slowing down traffic. I'm happy!
Keep in mind if you are evaluating buying this pipe that it needs to be tuned to about 8400 rpm. It's not a low rpm pipe. Not a racing pipe either. I bogs just a little on take off with the stock clutch kicking in at around 4000 rpm. I may consider a little stronger clutch springs but I need to get the slow jet correct first. I can tell the slow jet is too lean because as I went leaner and leaner to get the main jet right, the scooter got harder and harder to start.
-
Liking it so far
-
The Trek sure upped the fun factor on this scoot. I had no idea a 50cc could put out that much power.
I was so used to riding everywhere full throttle that I now have to be careful about speed limits and braking points.
Very happy already and I still need to fine tune variator for a little more rpm and maybe get a little higher rpm clutch springs.

That's cool, yes these are amazing little engines. Cheers

So I'm a little frustrated trying to tune this. I had installed larger main and idle jets and opened up air box by drilling a bunch of holes in it. Ran good at all throttle settings but was hard to start when it was warm. Then I opened up the snorkel and plugged up the drilled holes. I measured and calculated air openings, but now it won't start.
I tried the original idle jet and if I heavily choke it by covering the snorkel, it will start but I can't tune it to idle right or respond right as I open the throttle. It's a 35 jet and seems lean.
With the 40 jet in it, I can't get it to start unless I take the air box off and it will barely start even then, so too rich.
With 38 jet, I can't get it to start at all. Urg!
Will keep trying.

have you adjusted the idle mixture screw?, what's it set at?, maybe carb needs good cleaning?
-

Yes to adjusting idle mixture screw (when I can actually get it started). That's partly how I can tell lean vs rich. With the 35 slow jet it idles best, but not good with it screwed out so far that it's almost falling out. With the 40 jet, I have to have it almost all the way in (1/4 turn out) to get it to run. So I need something in between and as you'll see below, the replacement jets I have aren't exactly the same so I'll have to try various sizes.
When I first went to rejet, I cleaned the entire carb very well and it was running well after my first round of jetting and opening up the airbox so I think I have it clean enough.
I put the new idle jets under a 4x magnifying glass and discovered they are slightly different than the OEM jets. They have 3 atomizing holes instead of 4 and the atomizing holes are slightly smaller. Maybe they are slow jets for a 4 stroke. I have them in every size, so I'm going to try a few different sizes and see if one of them will work.
-
Where did you get idle jets? I got mine from jetsrus and if I remember correctly, the cheap generic idle jets didn't work for me either.
I ordered one and had trouble with it. So, after that I ordered OEM Keihin idle jets from jetsrus, and they worked well. Didn't have any trouble with the generic main jets from jetsrus.
-
I can't help on this as when I put on exhaust she ran fine with same jets in and two weeks later I installed the Dellorto I did absolutely zero tuning on the stock carb
-
Went one size richer on the idle jet and it will start with hand over snorkel and almost idle without. Still too lean.
Will go up two sizes and try again.

Took it out for a ride. Impressed with how much power and speed a fifty cc motor can make. Still need to upjet idle, but probably just one size, not two.

Went up one jet size on idle. Starts okay hot. Need to try cold start in the morning.

Started at first turn of key this morning and then died. Had to hand choke by covering the snorkel to get it going. I may quit fiddling with it now as its easy to hand choke when it's cold and it starts right up hot, even if its sat long enough for the auto enricher to kick in.
Think I'll now go one size richer on the main and see how it runs. Want it to be a little rich, not a little lean.
And still hitting 50 on the speedo on the flats. That's probably about 45 actual. There is no flat road with 45+ speed limit near my house where I can do a gps run. Now that I can get it started anywhere, I'll take it further away and see what gps speed I'm getting.

Been fighting a weird issue where it didn't want to idle when it was hot. Think I got it fixed with new spark plug

It hasn't been idling good so I tuned it up today. Took it out on the freeway just now to see how fast it will go with the Trek pipe I put on it. Speedo said 60ish. Probably only 53 or 54 actual. I'll gps it next time.

i want more speed and want to buy an after market exhaust but after reading this thread and hearing about the idle and starting problems, maybe i am better off just leaving it alone, i'm doing anywhere from 35 - 41 on the speedo as it sits stock with a smooth boss installed. most of the time 35 - 40 is just fine but rode it 45 miles up to south beach yesterday and wished I had more speed. plus when i got there, there are a lot of hopped up scooters running around south beach, made me want more speed....... what to do??? suggestions anyone?
