Hello everyone,
I'm brand new to scooters, but not new to turning wrenches. I'm an engineer for a major aerospace company and a maintenance officer in the Navy reserves as well. I just finished building a 95 Cobra on nitrous. Just looking around it seems to be a great forum with a lot of knowledge. Thanks in advance.
Picked up a 2002 People 2 stroke for 200 bucks. The battery is dead and it didn't come with keys, so I need to replace the battery and get an ignition key switch and the 2 locks for the seat and storage. Where is the best place to do this?
Also where is the best place to order factory parts?
Again, thanks in advance!
Mike

Kymco parts monster has been highly recommended here, and I have used them a few times myself.
http://www.kymcopartsmonster.com (http://www.kymcopartsmonster.com)
You're gonna want a new CVT belt/Rollers/spark plug/fuel, and air filters. All that + the Ign set should run around 150.00.
Do a compression test on the engine before anything else. 2t's wear out quickly or are prone to serious damage from simple mistakes. You should see numbers above 120 psi w/ the throttle held wide open.
Welcome to the forum. There are a lot of great people here.

Thanks for the reply! I found the ignition switches but it says "call us", I'm thinking this may sting a bit.
I see people referring to to their scooters as 2d and 4d. Are they saying 2 stroke = 2d and 4 stroke = 4d?
I'm going to call a dealer and see what my options are for a key today.
-
2T, and 4T. Yes that is the 2 stroke/4 stroke abbreviation. The ignition sets usually run 50 - 70.00 bucks.
The "call us" is generally for a non-stock item. It may take a few weeks to get.
Please keep us informed how you make out.

Got a batttery coming from amazon, ~21 bucks.
Got the below from the local dealer:
new ignition and storage lockset (P/N 35010-KFA6-E0B) ~45 bucks
"Special screw" ~5 bucks
Winker (blinker) lens ~10 bucks
Should all be here friday, tues at the latest. We'll see if this thing runs first, and go from there. I'll advise.
-
Compression test first thing. above 120 PSI w/ the throttle wide open.
-
Wilco Zombie. Can I do this with the kickstart or should I wait for the starter? No difference right?
-
No Diff!
I usually go three to four good stiff kicks to be sure.
-
What size socket does this spark plug take? Doesn't look like a standard 5/8, more like a 21mm (ish)....
-
13/16", 3/4" or 5/8" I forget which.
-
Has to be 13/16 b/c my 21mm fits loosely.
-
Ok. ... replaced the spark plug.
Compression test results- ~8 kicks and the compression continued to rise with every kick. I stopped at 210psi. I'll call that good.
My new ignition key at comes tomorrow but I couldn't wait. I clipped the green wires on the switch side of the plug and butt connected them, then put a switch between the red and black.
I installed the new battery that came Friday, put in fresh 2 stroke oil and filed up some gas (tank was empty). The fuel filter housing was not screwed on tight so it started pouring out. Tightened that up.
The scooter started right up but it smokes kinda bad and it has no power on the top end! I do have the air intake off, does this make a drastic difference?
Next step is to install the new parts tomorrow and clean the carb.
I'd like to get it running good stock and then look into derestricting it.
-
Most likely a gummed up carb, and air filter. It probably won't run at all w/o the air filter in place. Some do but most don't.
pull the carb apart. Every piece. Chem Dip is the best thing for an old carb. Soak it for 24-48 hours, and re assemble AFTER blowing out ALL the passages w/ Carb Clean/Brake Clean.
DON"T touch the Chem Dip. You will stink of it for days no matter what you use to get it off. A glass bowl of it or just put the parts in a gallon can of it. Use wires to fish it out or a screen basket. Rubber gloves are a must.
Also DON't put any plastic parts in it.
While your carb is being transformed to new, replace the air filter.
I also think your oil pump was leaking into the block as it sat. The compression would NEVER have gone that high unless the cylinder/rings were sealed w/ oil.
Since you rode it, most of that oil is gone so I would repeat the Comp. test just to be certain it is good. 140 is the highest I have seen in a scooter engine
-
any idea where to get a cheap little air filter that will clamp to the carburetor? I'm assuming I'll have to re-jet....
-
Ebay/Parts for scooters.com/just about every scooter site has them. Usually around 10 bucks or less.
If you get one... stay out of the rain, and covet it w/ a plastic bag when you wash the bike.
-
Alright, parts came in. Hopefully I'll be able to install tonight. I got an air filter from Autozone (Spectre 4282, $11) if it helps anyone.
I pulled the seat off last night and removed the carb for cleaning tonight. I have a new question:
Fuel filter housing - When I top off the gas tank, this housing basically pours fuel out the bottom. I've unscrewed the housing, reseated the filter and screwed the housing back on multiple times and it still seems to leak. Seems a simple solution would be to remove the entire housing, cap the vacuum line and install an inline filter with a manual fuel shutoff valve?
I'm also working on some pics!
-
Got the ignition switch installed, cleaned the carb and removed the vacuum regulated fuel filter. I installed a manual fuel petcock and inline filter-works great, no leaks.
The bike starts right up and idles pretty good, but I can't get the bike to go faster than about 25mph. It feels like it bogs when I roll any more than halfway into the throttle.
I pulled the front cover off and it appears the person before me clipped the green wire on the bottom of the CDI and installed the connector. I drove the scooter with and without this connected and it makes no difference.
I ordered a derestricted boss today at the dealer. With the CDI wire clipped, I'm wondering if a dealer did a derestriction already. Tomorrow I'll pull the CVT cover and look around.
Any thoughts?

any help?

Dude you want to make sure you leave that green wire unplugged/clipped it gets rid of the rev limiter. There's a possibility whoever did that didn't derestrict it fully. You want the main jet larger, the wire unplugged, and the smooth variator boss. The older p50 should hit 50 on the Speedo no problem when running right. If you have issues not being able to give it full throttle that means your carb is dirty or not tuned right. Make sure you have between an 82-85 main jet and have the mixture set between 1-1.5 turns out. Make sure you have a fresh NGK br8hsa. When you install the smooth boss measure the width of the belt and make sure it's not below 17mm, replace if so. Inspect rollers for flat spots. I love the people 50, and they haul ass once everything is set up right.
-
Alright, sounds good. I've got the variator boss on order, I'll measure the belt today.
Where can I buy jets or a jet kit?
-
Jetsrus kicks ass they delivered my zuma Dellorto jets in less than 3 days, and shipped the order same day. You should get #82-90 in the event you modify the scooter later on.
-
Good idea. I'll get the 82-90 ordered. I'm guessing what Chachivoodoo lists here is what I need?
http://www.kymcoforum.com/index.php?topic=3334.0 (http://www.kymcoforum.com/index.php?topic=3334.0)
I'm going to order a belt too. I pulled the variator and clutch out. The belt only measures ~15.68mm and people are telling me to replace if it's not at least 17mm. Will a factory replacement be ok? Looks like this one has P/N 23100-KEB7-9000.
I cleaned the rollers while I was in there. They don't appear to be damaged or worn. Should I be replacing those?
Thanks in advance for your help.
-
Ouch that belt is gone!!!! You might as well order a set of 8.5g Dr pulley sliders, gain a little acceleration and top end. That is the correct part number for the belt. You might as well replace the three sliding bushings too, the little triangles.
-
Ok....New main jet (85), new replacement Kymco belt, smooth variator boss.
I can't even twist the throttle over 1/4 before it bogs. Is it possible the exhaust still being restricted could be making it bog? Carb float bad?
The carb needs some tuning. Got anything to read?
-
Do you have a pod filter? If so you need wayyyy larger than #85 main jet, prolly closer to #100.. Stock airbox > pod filter
-
Are these things seriously that touchy? You can go 50 mph on a stock airbox?
I have this:

-
Yeah dude, any carburetor is that picky. More air needs more fuel, it has no way of self correcting. You will NOT get a performance gain from that air filter. The stock airbox is the way to go and yes with your p50 it'll do 50 bone stock if its running right. Slap that airbox back on.
-
Well that did it. Stock airbox back on with the restrictor out and 1 full screw turn on the air/fuel mix and it buries the needle to 50mph. My GPS app says 40mph though.
Still need to derestrict the exhaust too.
Thanks for all your help!
-
What year is your bike? If its older than '07 the pipe is totally derestrcted already!!! Glad to hear it rips!
-
It's an 02.
-
Your set then!
