got my heads back, 94cc , 2100 /1650 ex valves, 124 jugs flat top piston, 662-2 tman cams 108comp , assemble time, but hav to clay piston for valve clearance

 

That is a standard practice especially when you have very high lift cams like the 662-2's. Do you have a question about it?

 

that's 10.8 comp ...

 

Yeah you didn't fool me, I knew it was 10.8 comp. Detonation would have been horrible at 108:1 comp. By the way, you could have done an edit on your post and just corrected that mistake, that is if the forum is working correctly.

 

Don't know what type of bike it's going in but I can say you will like the power. The 662 is going to come on fast. Who did the heads. I'd like to try the 662 but would have to change some stuff to make it happen and in my case isn't cost effective.

 

Stop teasin' and tell us more!
