hello there. i am going toask you guys here before i tear into me shee. i am pretty sure i no the anwser but i hate to split the case to replce the crnak seal.
but anyhow wde open itruns like a beast at idel it sucks reall slugish like untill mide throttel then it kicks hard nice and smooth. i noticed sitting on the bike the rite pipe is cold and the left pipe is hot also the right pipe/cold also spitts oil i mean itsso bad it drips out of the slincer this is on the right side if yor sitting on it. whats thropwing me off is the right side/cold side carb idel adjut realy nice but on the left side the carb idel alost does nothing at all. but the right sid eis my problem with cold and oil spitting . so basiclly is right side spits oil. cold pipe. white smoke. carb adjustments work
left side hot pipe no oil spitting. and carb doesnt respond to any adjutments.
by the way i put rings and new gaskets to fix it it didnt help.
well if it is thecrank seal i heard people put them in by just pushing them in from the side case. does this work? i alwas took the case in half.
thanks

 

Try switching plugs and coil wires and see if the problem changes to the left pipe.

 

hey i changed the wires like you said still was runnig cold on tthe on side i even changed plugs after and it ran fine for about 2 mintues then fouled ut again well i thought so.
but truned out that the wre that plusinto the coil was in to were someone has spliced the kill switch to it and blacked taped it up. so whni changed plugs i bumped that wire enuff to make it fire untill it vibrated apart again. must be why runni it wot it was fine it must make more sprk faster it runs. bu it is all good. i jst glad i didnt have to do the cranks seal lol.
thanks

 

Crank seals are no fun lol. Glad you figured it out. Post some pics if you can.
