i'm assuming i should replace the ring?

also on SOME polinis when you tighten down the intake nuts too tight it lodges the piston inside. I have seen it with my two eyes...so if you're worried about air leaks, be careful smashing down those bolts.

You should do it, not just look into it.

You dont need to replace the ring, unless there is signs of blow-by

harold, not everyone seizes un-portmatched polini's. I'm not recommending it, but I know some peeps that haven't and are going strong. Crazy enough, my polini made more power unportmatched! (??__+_)

"Could be a tuning issue, too rich equals too hot at some point as well you know." never heard that could you please explain how that works

also the intake bolts are important that they are not hyper tight or too long, i think the holes go strait to the case studs if i rember correctly and that can cuase warping and alot of issues.

also how do u know its tuned right? just cuz ur rich at one place doesn't mean its rich at all throttle locations, also how much oil are you running? What size jet? carb? is the motor rebuilt? are you surer there are no air leaks? also make sure your not running too hot becuase the timing is full advance and the gap is too big. also make sure ur electrical is not giving you the false impression of being too rich.

tuning tuning tuning, champher the edges of ur polini ports as well.
