i do not know exactly how your ride went, but..
depending on conditions, super revs, up alot of hills, warm air, one could float the valves. [if that's the case] just wait a day and it will run fine. sometimes hours. [and if you use]regular grade gas could cause vapor lock,flood the valves(float)and make a motor run like crap. top grade gas is better all around because the hotter spark lets you not have to work a bike as hard. less gas dumped in carb. runs smoother.
to keep up with traffic this bike has to be run hard enough to possibly cause a vapor lock.
like i say, i don't know what gas you use or how went the ride other than what you said.
hope that's all it is. cause that's an easy fix. and easy to avoid next time.
i know, sound like i floated a million valves. i have.
not really a million for all those college kids who are counting.

Thanks for the tips. I run it on 98 ron/octane so should be ok on that front

if you bought a sprocket from the no longer existing chinamoto on line store, toss it in the trash. safety hazard. i got one from old bike barn, its %ages better all the way. (38t)

going to hook the blue and white together and leave the green alone.
headlight blinding. tested it today.

i dont see that cut blue/white wire in my wire groups. What color wires are next to that cut blue/white? looks like a yellow, brown and some white striped something.........can you see where the other end goes or ends up??

so both blue/white come from the front? I will remove my tank and have another look.

Thank you

Thanks for all the input on the sprocket. I got a 38 i picked up from amazon a couple months ago that has a silver plating on which i am going to sandblast and paint black before i mount it. looking forward to this upgrade. Just hit 100 miles yesterday and the bikes running 100%. Got to change my oil now.

BTW, i ordered one of those electronic needle tachs from amazon and it arrived today. I plan to take the tank off in a week or two to repaint the bike and i will wire it up then. Ill keep ya all updated on how and if it works.

This is sweet. Where do you connect the wires?

This is sweet. Where do you connect the wires?

wires connect to:
ignition on 12v positive, ground, headlight on, and neg terminal of the coil.

dandaman- how did those sprocket bolts fit that you just got on page 326? did you have to cut them for length or do they fit right in?

[DanDaMan]

direct fit
