ok thank you to all that responded to my previous post but now i have some more info to ask now if i blew the crank seal and i have the bike tiped on its side will the oil stay in the side case instead of running back into the motor ???? And can u tell me what and how to perform a leak test and one more . To replace the seals is it a job i can tackle or not? thanks again everyone.

Seal would have to be totally gone for oil to pour into engine , oil gets sucked in during engine operation. There's a sticky at top of repair/mod section on how to build tester ,or try Harbor Freight. Test involves pressurizing engine to six pounds., If it holds pressure for six minutes it's good. If its leaking on clutch side you might be able to hear it.

Do a leak test, there are a couple of threads on here about it. If your crank seal is bad the motor has to come out and the cases have to be split to replace the crank seals.If you have to slit the cases, then you need to make sure that your crankshaft, clutch basket, shift shaft, and kick idler gear are all in good shape. While you are in there, I would have the crank trued and welded if it is not already. You will also want to look into getting a modded shift star, a modded shift shaft, a pancake bearing, a billet clutch basket, and a billet water pump impeller. Every thing except the crank can be installed by just removing the clutch cover so the crank is the most important.You can research all this stuff on here just by doing some reading and I also recomend getting a service manual. Splitting the cases is not hard if you have a manual and work in an organized manner and take your time.
