Engine won't turn over after clutch adjustment *Update 09/05*

*Update 09/05*

I went back to the drawing board. The clutch adjustment was poor timing because when I adjusted it so it ran I still had a hard time. The JRL carb was the problem. I put the stock NT back on and it ran like a dream. Don't know why or how but this has been driving me nuts for two straight weeks. It would sputter and I would have to pedal for 30 yards as it acted like it wanted to start and eventually turn over. She fires right up now.


Bike has been working fine all day. I have a 20 mile round trip tomorrow so I wanted to do a few things.

1. Replaced the chain tensioner nuts and bolts with higher quality stuff.

2. Wanted to loosen my clutch by one notch. I have the clutch where you press a lever into the notch (not the push pin one) and I noticed that when I have the clutch pulled all the way in versus when I have it in the last notch that there was some resistance. I loosened it by one notch in the flower nut.

Normally, I pedal and at the same time I stop peddling, let go of the clutch and hit the gas and it fires right up. Something different happened, the bike just skidded not even a sputter. I was like hmm, this is strange. The second time I did it I pulled on the throttle twice and then it started. I shut it off, tried it again and I would have to blip the throttle to get it going. Now it won't turn at all.

Checked my.throttle body, cable is in correctly, checked the my carb (JRL) and my throttle cable is in the slide correctly, jet needle is good.

I'm unsure what else to do. I took took the cover off the clutch pads to see if the spring broke and everything looked good under there.

Either this has to do with my clutch adjustment or this was going to happen regardless.

Sounds like you're slipping the clutch because of that adjustment.

The thing though is that I adjusted the flower nut to how it was before it happened. When that didn't work I started from scratch and redid the adjustment completely. Still nothing.

Let's assume for a moment that the clutch adjustment has nothing to do with it. You also altered the chain tension when replacing the hardware, and this too would affect startup.

This is interesting.... Let's say it is that, what would someone have to do to the chain tension to cause the bike not to start?

Take the spark plug out and see how it turns over.

It has spark.

Dumb question, have I been starting it wrong and I have somehow ruined my clutch assembly?

So I pedal, stop peddling and at the same time letgo of the clutch and hit the gas

With the spark plug out you're not checking for spark, but instead you want to see free engine movement.

No, no, no...you pedal and keep on pedaling while you let go of the clutch and hit the gas...That is how you do it...You need that pedal action while starting it...NOT stop pedaling and trying to start it.

I always keep pedaling until the motor starts and begins to get going on it's own and warms up ready to go.

No idea. I was just offering a perspective shift so you didn't get stuck on one thing.
