Ok i have a 1994 yamaha warrior, i just got it bored 20 over, got the wisco piston to match ok. so i got and put the top end back together and it wount start, it will backfire somtimes but thats it.
I checked for spark... good check for gas...good check for compression.......maybe 20psi
WTF i just had it bored and a new piston and rings. now if i put a cap full of oil in the cyclinder and crank it, it has tone of compression. i have the piston installed right (arrow pointing to the exaust) ajusted the valves checked the timing i even tryed retarding and advancing the timing but in the end i get nothing... can someone plz help me im trying to get it up and running for rumble on the ridge..
