I've adjusted thr valves already, they were set quite tight. But yeah it's not hitting thr rev limiter. it's weird because this is a new issue, starting only this week. I rode a sustained 60 for about 45 minutes, everytime idgo right above 7k, it would start misfiring and i could feel it jerking, take it back to 7k ans it's okay. at first I thought it was jetting, but it is fine full throttle up until 7k

I'm running a 112.5 right now. i was running 115, but when running a long time , itd bog down real bad at full throttle. i had to stop like 4 times on the way to an off-road park after extended 55 mile runs. I haven't had the same bogging down issues on this past long rude.
it just doesn't want to go past 7k anymore, even in lower gears. it just starts misfiring almost like hitting rev limiter but more bouncy. My co-worker said that the loose head gasket could be causing me to lose compression and cause thst misfire. He noticed it when it was super minor, and it's worse now. |

I'm able to get the engine to hit the rev limiter at 8500, however right at 6500, it starts to lose power slightly and by 7k it sounds almost like its hitting the rev limiter, but I'm pretty sure it's misfiring, like every couple times. My head is leaking oil, so thisbqeekend I'm taking it off and while I'm at it gonna do some porting and decking , I bought a new head gasket from csc, and then retighten the head. I'm thinking it may be losing compression. I'll report back if it fixes the problem. if not then I'll replace my ignition coil i guess |

you think so? The thought crossed my mind. The only weird thing is it was fine like 2 weeks ago, with the same jetting. and before thst it was bogging down at full throttle so i went a step leaner .
You might be right though. |

I know this is an old thread but thanks for this Jerry! I think I will follow your lead on the stick coil, I've put them on my old connie in the past and it really helped, especially with cold starts.
Also, I don't know how I missed it but I didn't know about the Chinariders Link Referral Program, I'll have to use that and help out a little. Again thanks!

I tested the cold start out Saturday morning. 43* brrrrrr, but fired right up. It was a chilly start out in the morning but warmed up to 62* by noon. It was a beautiful sunny day. Spent the day at one of the local fall festivals and car show.

Quick question about the Referral Program, when I put the amazon link you posted for the stick coil and plug it goes to my Amazon page and I have everything in my cart. Does Chinariders benefit more if I put each individual link into the box one at a time or can I put the link in the box and buy it all out of my cart?
