thanks everyone. it has its problems the owner said.. i just pulled the rear tire off and cleaned the rim.
the chain was so loose i could almost push it together in the middle. and the rear sprocket..... well ill have to post a pick.
p/o said it made a weird noise and would lurch/jerk. lets just say i hope its just the rear sprocket skipping teeth it was that bad.
dropped the oil pan and everything looked great. top end looked very clean and perfect.
waxed all the fairings and it shines. now off to make a wishlist for parts i need.
