Well, I finally got my 4 mill cheetah cubs put together and rode them for memorial weekend. Awesome top end power, but no low or mid. So, i jetted all weekend. Got to where the plugs looked nice and tan, but still the same performance. I did a compression check a couple days ago. 125 on each cylinder!! :angry: So now i have a new set of problems...why only 125? I go down to the local shop to pick up new domes. i was running 19cc, and thought 17cc would be better. He said they would bring me up to about 160, and to check the clearance and squish at the top of the piston. So, i take the coolhead off and go buy a vernier caliper. With the piston at its upmost position, i am still running with .049 clearance. So since i am in there, i decide to check the stroke. I go over it like 10 times to make sure i have the right readings. I should have been reading at 58 mm, because it was supposed to be a 4 mill crank. But i was reading at 54.02mm. I bought a crank of the internet from in2glamis like2 1/2 years ago that was supposed to be a +5 longrod stroker crank. Well guess what, the sum bitch is stock stroke!! :angry: Now to get my motor to run right, i have to get a new crank. Just a little pissed and need to vent.....sorry for the book!!

It wasnt even a 4mm shorty...it was a stock stroke crank.  It ran, but it was all or nothing!!  No bottom or mid, but lots of top!

haha, no. i meant that the crankshaft travel was 4mm less than it should be. i guess it be like having that spacer plate for nothing. lol
