jcanapa Posted October 30, 2003 Report Posted October 30, 2003 I month ago I had been gettinf oil in my right side crank case. I was burning heavy smoke and it ran like ass. I replaced the seal and it rode fine for about 3-4 hours then again it started to do the same thing. I had my cases checked out and they are fine. When I replaced the seal I did notice that on the primary drive gear there was a small grove wore in to it. I can slightly feel it with my finger nail. Do you think that this is causing the problem? Any help on this would be nice because Im getting sick of pulling apart the motor. Quote
Dragg-on Posted October 30, 2003 Report Posted October 30, 2003 I WAS ON THE SAME BOAT AT YOU MAN! i KEPT GETTING THAT OIL IN TO THE MOTOR, i SPLIT THE CASE LIKE 3X, i CONTACTED MP RACING AND SAID THE SAME THING YOU TOLD ME. THEY SAID IN HIGHER HP MOTORS, THE STOCK 7 BALL CLUTCH SIDE CRANK BEARING EVENTUALY FAILS, DUE TO THE EXTREME SIDE LOAD CAUSED BY THE HELICAL GEARS THAT DRIVE THE CLUTCH. THEN THE CRANK WILL MOVE UP AND DOWN LETTING SOME GEAR OIL TO FALL IN. WHEN i SPLIT MY CASE, I FOUND METAL PIECES AT THE BOTTOM OF THE CASE WHICH I BELIEVE WERE FROM THE BEARING, THE TZ CRANK BEARING FROM THE TZ 250 STREET BIKE ARE 12 ROLLERS AND ARE 4X STRONGER THAN THE STOCK ONE. I BOUGHT ONE FROM MP RACING. PRICEY BUT WELL WORTH IT! SORRY ABOUT ALL THE CAPS, HOPE THIS HELP, ANY QUESTIONS LET ME KNOW! DRAGG-ON! IVE GOT PICS OF THESE BEARINGS IF YOU WISH TO SEE ONE, JUST GIVE ME YOUR E-MAIL Quote
