[QUOTE="razorboy, post: 1403434, member: 62244"] Crank is new and all seals were installed correctly. The entire bottom end is new and with the exception of the cylinder and head, so is the top end. So I had a leakdown tester for a Honda RS125 and my machinest whipped me up a new insert to fit the KX85 motor. I pressurized the intake to 4 psi and it dropped about 1 psi per hour. So a little under 2psi after 2 hours. Tried to go higher but the line won't hold more than 4-5 psi without popping off. From my research, seems like 1 psi loss per hour is pretty healthy. Sound good to you guys? It may simply be a problem with the carb but won't know for sure until the new float valve arrives. Strange that it only gets up to about 120psi of compression and according to the manual, thats the low end of things for this motor. And also strange that it simply won't fire. Seems like it gets flooded before it can even get a good kick. If the float valve doesn't help and I can't find anything else outwardly wrong, I guess I will pull the cylinder as suggested to get the runout checked on the bore. Cheers Bernie [/QUOTE]
