[QUOTE="ALOHA, post: 1367631, member: 111206"] I am having a real tough time getting my 1981 yz465 to run properly. Problems I have experienced: 1. Very hard to start. Kick, kick and kick some more before it starts. 2. Will not run above 3000 to 3500 rpm. from 1/2 throttle to full throttle it just blubbers. It will not clean out. What I have done: 1st over bore, new piston and rings. (piston is in correct) New seals, complete motor. gone through the carb 4 or 5 times. Now has all stock jetting. 45 pilot, 390 main, new needle and needle jet. reset the float a little lower from the 1.1 height called out replaced the coil under the tank. replaced the stator on the crank. No change. It still will not pull after the 1st 1/3 of throttle and just blubbers. Still will not clean out regardless of how long I keep the throttle on. Any ideas. It's driving me nuts Thanks Jack [/QUOTE]
