I did a compression test on my bike and i'm only comming up with 100 pounds something i'm doing is not right i know the bike has more than that. The instuctions say to crank five times to get a complete reading i followed directions but not sure if theres somthing eles i should be doing. Is there a trick to this that i dont know about please help.... Thanx in advance

Can someone please define exzactly what is port timing and how to tell if, or by what marjine it is off, and the possibilities of port timing being off, and of couse what cuases it??? thanx guys.

SDD, Now i have new cylinders ,head, carbs,stock bore, milledhead, 35mm pwk's with a moderate hill port or dune port call it what you will. My timing is advanced 5 degrees everthing is less than ten days old. Do you think its a CDI or timing problem i can't think of anything else because everything is new. I checked all of my bolts and gaskets for leeks twice over this baby is air tight, left side just wont fire as well as the right

when i say i blew a plug i mean the plug melted once and the second time it just blew up, but did not blow a hole though my piston just damaged it and the cyilinder real bad. at the time of all of this i was running 66.5mm pistons and 17cc domes. Also i am running vp110 fuel as instructed by many builders because of compression, but i do not know what copression im running

PLEASE someone point me in the right direction. My bike has a hill port stock bore 64mm weisco, pwk's35mm, v-force reeds, t-5 pipes, milled head, hot rod crank from the cases up is one week old AM I WASTEING MONEY???
