General Discussion / bought a new old Honda on Saturday
« on: July 11, 2023, 11:30:53 PM »
I've had my eye on a 1980's Honda Nighthawk 650 (CB650SC) for a while. I finally bought one on Saturday, a 1984 with 21K miles. The seller messaged me with a very low price (actually much lower than we'd agreed upon earlier before he couldn't find the title) and I jumped at the opportunity. He had a new title all ready to go.

I rode the bike home from Chicago (206 miles). The lack of front brakes (leaking fork seals had soaked the rotors and brakes), the somewhat sketchy, dry rotted tires, ancient gas in the tank and marginally working hydraulic clutch made the ride home a bit more exciting.

Bike looks beautiful from 10 feet..up close she's a little rougher. Nothing is very expensive on the 'to do' list...seals, clutch and brake master cyl rebuild kits, clutch slave cylinder kit, cylinder cover gasket, front brakes, maybe brake hoses/lines and tires. Other than tires i'll do it all myself.

Very comfortable bike, soft seat, plenty of power and a smaller rider triangle than I'd expected, which is fine because I'm short.

Once complete it will be a very nice bike.

General Discussion / looking at motorcycle, fork oil leak
« on: May 27, 2023, 02:56:24 PM »
I'm on the hunt for a 'new' motorcycle..I've found a really nice Honda Nighthawk 650 that I had lusted after in my youth. Bike is in great shape for a 40 yr old bike but not perfect. Current owner has had it for 20+ years and has stockpiled a huge parts supply with the original intent of keeping it (and keeping it running) forever. I was going to go look at it today, buy it and ride it home (200+ miles) but seller called me last night saying he can't locate title, so it's on hold until he finds or gets new title.

Enough with the intro...he also called me to tell me bike has fork oil leak that he hadn't noticed when he put it away last season. With forks the leak would either come from the bolt and washer at the very bottom of from a bad seal, leaking down the fork leg, which would also probably eat the paint away. He has new fork seals in his parts stash and I would have no problem replacing seals and fluid once I get bike home.

In attached pic you can see the spot of oil on the tire. It looks like rolled forward or back, that's why oil is not under fork.
I obviously won't be able to fix this at the seller's location so I'll need to ride bike home. I know it's not the wisest move but unless the oil is pouring out it should be ok, right? I don't have the option of trailering it so it's either ride it home or forget it. What do you think?

(edit - I was all set for an adventure today, riding a 40 yr old bike home for about 5 hours on all 2 lane highways, passing through small towns on a beautiful, sunny day in the 70's...willing to take a chance and hopefully have a good story to tell about it)

General Discussion / Sunday morning detail / polish
« on: April 30, 2023, 05:13:38 PM »
still waiting on a tiny part for my carb before I can get it reinstalled in the S200 and actually start riding it this year! I was looking closely at the paint last night and didn't like what I saw (swirls in the black paint under a bright light).

Pulled out my Griot's dual action polisher with a small, 3 1/4 inch orange pad, Meguiars 205 polish and hit the front end and fender of the scoot. While far from perfect the swirls are all gone and it looks much better. Top coated with a Turtle wax spray ceramic coating that lasts all year and beads water like crazy.

If anyone ever wonders how a dual action (random orbit) polisher does on paint, wonder no more. It's basically fool proof, you can't burn your paint like in the old days of straight polishers and wool pads. I've used it on my cars and bikes for a decade or more. Works like magic.

dropped off my little Ninja today for tires and chain/sprockets at my local full line dealer. Was a little hesitant to bring in the bike as severe weather is predicted for this afternoon (storms, hail / tornados)...and I only have insurance on the bike if I hit or hurt someone, not if the bike gets blown over or destroyed in a tornado! They assured me they will keep the bike inside.

while wandering around looking at bikes I saw not 1, not 2, but 6 new Kymcos in stock! I have never seen more than 1 Kymco scoot there, before. They were loaded to the rafters with new bike inventory from all makes.

2 Super 50X's, 2 Agility 125s and 2 AK550s. The little scoots looked a lot 'tougher' than I remember, with wider fenders and bodywork. I've never seen an AK up close and it looked good, but smaller than I imagined. It felt good to sit on it but the seat seemed quite hard. Both AKs were gray and said 'super touring' on them.

First time I've ever brought my bike to a dealer...work estimate was $450...plus the $350 I already spent on tires, chain and sprockets. Spendy little service!

General Discussion / hard starting without baffle
« on: April 03, 2023, 03:41:25 AM »
this is more of an observation than anything...but I'd pulled the baffle out of my slip on muffler on my little Ninja in January. It sounds great with it out, if not just a little too loud. ..but the first time I started it without the baffle I noticed it went from the usual Da-Da-Vroom, an immediate start, to more of a Da-Da-Da-Da-Da, nothing...Da-Da-Da-Da-Da, nothing...and finally Da-Da-Da-Da-Da-Vroom.

I chalked the first slow start up to it sitting, cold, for many weeks. Same thing happened the next time I started it..a  very slow start..and then today I put the baffle back in and it fired right up. Da-Da-Vroom!

So I guess the bike needs a certain amount of back pressure to help it start efficiently? I wasn't expecting such a difference with baffle in vs baffle out.

watched my Iowa Hawkeye mens basketball team lose their first round game last night to Auburn....so to work off my frustration I pulled my carb from my S200 (it was on my to do list before riding season).

There is something very satisfying to me in disassembling a carb in prep for a thorough cleaning. Of course my pilot jet was clogged...for the 22nd time. Planning on spraying all the passages with carb cleaner and also soaking the whole unit in carb cleaner (belt and suspenders?). This is the price I pay for putting very few miles on a bike with a carb.

I will be replacing 2 parts (circled in red in the pic). The o ring for the air fuel screw is kind of boogered up and the diaphragm that is on the upper side of the carb, and attached to a vacuum line has a pretty good pinch in it. Both are cheap so will be replaced.

I'll admit I have no idea what the diaphragm (about the size of a US quarter) does on the carb. Can anyone fill me in?

General Discussion / took a ride today with new headlight bulb
« on: March 05, 2023, 08:46:24 PM »
finally joined the 'dark' side...and installed a brighter, whiter led bulb in my Helix. It was a pain to install as the bulb heat sink is much larger plus there is very little room between the steering stem and the headlight bulb. After about 90 minutes I had it in. Definitely whiter and brighter but not sure about the beam spread as I haven't seen it at night. I do have a pic here of both bulbs side by side with the old on the right side, new on the left.

I'm actually not concerned at all about beam spread and blinding others at night as I never ride at night and have no intention of doing so. My sole purpose is to increase my visibility to others.

Included a pic today when I stopped at my old fraternity house in downtown Iowa City. Can't tell much about bulb brightness in the pic..

General Discussion / scheduled apt at motorcycle shop
« on: March 04, 2023, 04:47:25 PM »
my little Ninja has about 14,500 miles (~23K km) and it's time for new tires, chain and sprockets. I probably should have called the shop in Jan or Feb but I waited until today to set an apt. They can get me in on April 5...about 1 month from now. I guess that's really not too bad, considering this is likely approaching their busiest time of the year.

I have all the parts and I suppose I can live without riding my bike for another month. I do have a section of chain a few links long that is a little rusty and very stiff. Very stiff. Last time I adjusted my chain I set the slack on a normal spot and not from this tight spot. When I spun my rear wheel around it actually stopped and reversed itself when it hit this tight spot. I readjusted the chain slack and it's ok now...but I will be very happy to get a new chain and sprockets to last me another 7 or so years.

Is anyone else scheduling any Springtime service with their shops?

General Discussion / rode my buddy's new Harley iron 883 (sporty) yesterday
« on: December 31, 2022, 04:29:06 PM »
My one buddy who rides (and just started) bought a new Honda Rebel 300 in May. He did what many do and rode his first bike for a few months and began planning for an upgrade. For Christmas he traded on a new Harley 883 sportster.

I stopped by his place yesterday to take a look at the bike. I must say it was pretty cool. Low seat, blacked out and the throaty rumble from the (factory!) pipes. I wasn't planning to ride it but he wouldn't take no for an answer, even though I had no gear at all (helmet, gloves, etc.). It was a balmy 30 degrees F but I took it for a quick spin. Just a few blocks out and back.

The pure mechanical noise and vibration was really cool. This is about as basic as a machine gets. It was really fun on my brief ride. I can't wait to spend some more time on the bike this Spring when the weather is nicer. I never imagined I'd be so excited about riding a Harley!

pic of similar bike attached.

General Discussion / installed my Christmas present, tonight
« on: December 30, 2022, 01:36:50 AM »
I bought myself a Utopia backrest for my Honda Helix for Christmas. I love the comfort of the scoot but due to the cruiser-like feet forward riding position, there is no support for your back. I would describe it as sitting on a bar stool vs sitting on a chair with a back...you can only sit on the bar stool for so long!

Installation was a bit challenging..but I got it installed and will have to wait for better weather (as in March) to test it out!

General Discussion / labor rates at my local motorcycle shop
« on: December 18, 2022, 03:25:03 PM »
I was in my local motorcycle shop earlier this week picking up a filter and some other items...and they had a paper with their labor rates written down on it, posted for all to see. This isn't to complain about labor rates but merely to comment that I don't recall seeing a 'tiered' system of charges.

It read:

$119 / hr tires and scooters

$129 / hr maintenance

$149 / hr for diagnostics and repairs

Eye Candy | Videos and Pics / who loves ya, baby?
« on: December 15, 2022, 04:52:34 AM »
my bikes, that is...showed my bikes a little love tonight with an oil and filter change and brake fluid change on the Ninja 300. Mobil 1 4T, Kawi OEM filter and Bel Ray Dot 4 fluid. I had enough brake fluid left over to also do the brake fluid on the Helix. Fluid was dark (on the Helix), even though I changed it a year and a half ago. I think I didn't clean out the reservoir well enough as last year it wasn't brake fluid in there but old, dirty brake paste! I think the fresh fluid slowly dissolved the film in the bottom of the reservoir. Oh well, new fluid all the way around.

I know not everyone like wrenching on their bikes, but I find it a Zen like experience to be in the garage working on my bikes with good music playing in the background.

Eye Candy | Videos and Pics / a 'Stig worthy' seat and drained carb bowl
« on: December 14, 2022, 03:02:48 AM »
did my end of season oil change on my Helix tonight and chuckled as I put the Helix seat on the Kymco ...thought that THIS is the kind of seat Stig needs on his Like! ...but then he might be in a sportbike riding position as the bars are about at seat level!

Drained carb bowl on Helix and about 2 oz of gas came out. I always drain carb bowls at season end (or even if I won't be riding for a few weeks). I don't think everyone realizes how much gas sits in a carb bowl...waiting to gum things up.

29
as the title says...I recall questioning this when I had my motor apart earlier this year. A scooter crank has 2 sets of sprocket teeth on the stator side of the crank. The inner sprocket runs the oil pump...the outer sprocket isn't hooked up to anything. Can anyone explain why?

General Discussion / overfilling gearbox oil
« on: December 03, 2022, 05:39:17 PM »
this discussion comes up fairly frequently...the question of how much oil to put in the gearbox of our air cooled Kymcos. Many people make the mistake of filling it until the oil dribbles out of the fill hole. The actual quantity needed is stamped on the bike...typically 180ml.

A youtuber who has been rebuilding his Agility 125 recently filled the gearbox until it dribbled out, realized his mistake, then drained the oil to measure how much it took to come out the fill hole. 600 ml came out. On a bike that calls for 180ml.

I've never seen someone actually measure the overfilled quantity..but wow, that's a significant difference. When I bought my scoot it was overfilled this way. The excess gets vented into the airbox where it soaks (and ruins) the air filter.

Wanted to share this as I thought it was interesting to see it takes 600 ml to come out the fill hole.
