well first off im not on here much but i figure someone could help me out
here the story
i have a 98 banshee, i had a shift lever seal leaking so i went down to the stealer and ordered a new seal, i figured since im taking the seal out i will change the oil. (which wasnt neglected in the first place) shifted strong, no noises what so ever. when i drained the oil it looked pretty clean no metal coming out or nothing. i asked the dealer what kind of oil goes in it to be on the safe side. he sold me (this is what is on the bottle) HP4 Hi-performance 4-stroke motorcycle oil SAE 10w-40 SJ, Synthetic/Petroleum Blend Without Moly. he said it took 1.6 qts so that what i put in it. i started it and let it warm up (like normal) and took off down the road. i made it probably 1/2 mile down the road and the clucth side started whining like a SOB. i shut it off and pushed it back home. as i was pushing it in neutral it still made the noise. being suspicious about the oil i drained all back out and then puched it down the driveway without oil in it........the noise went away.
so my question is, Is that the right oil that goes in it? i called up the stealer and talked to the service manager and he said that it might be possible that the guy i bought the shee from has put a heavier oil in it like 80-90. i looked up what oil goes in it and it says SAE 10w30. so my other question is if the guy before me put 80-90 in it wouldnt that mean there is a problem? or should i put 80-90 in it and see it if gets rid of the noise?
thanks for answering my questions
