kinder Posted October 28, 2007 Share Posted October 28, 2007 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 Link to comment Share on other sites More sharing options...
Moderator YamaHead Posted October 29, 2007 Moderator Share Posted October 29, 2007 Sounds like it might be sucking air in through possibly 1 of those new seals After starting attemps, Is the plug dry or soaked with fuel? Link to comment Share on other sites More sharing options...

kinder Posted October 29, 2007 Author Share Posted October 29, 2007 And too, does the engine get it's lubrication through the slots in the piston? 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 Link to comment Share on other sites More sharing options...
