Posted October 28, 200717 yr Hello, just joined --I wanted to know what the heck i'm doing wrong with the above trimoto. I rode the bike, it worked but noticed a "rattle" inside the motor, --it was the clutch-side main bearing. I took the engine apart, replaced both bearings and seals. put it back together and it won't start. i replaced the stator, the CDI, the plug, and it still won't run. Now i'm wondering if i got the piston in backwards?? the slots in the piston are turned toward the carburator side, the piston has an arrow on top and i pointed that toward the front tire. I spin the engine with a large drill and still it pops shoots a little fire out of the exhaust but still will not start---so,--what's wrong>>>??? - Kinder - thanks for any input

October 29, 200717 yr Author Your turning the engine the wrong way. No, I'm turning the engine the right way (towards the front countercolckwise) thanks, Kinder

Some two cycle engines pull the fuel mixture directly through the engine crankcase then through ports up sto the intake on top oif thee pisto. But evidently this type engine draws sthe mix through the piston when it is down--- I just dont know. - Kinder
