My bike is with 1200km, was downloading a lot of oil and strange noise in the clutch and engine. she's burning too much oil.
I took to solve the problem in honda authorized, in the factory warranty.
The mechanic told me that is wear on the rod, clutch burned, and have to exchange the rings that came with factory problem.
I recommended not to use more oil that Honda recommends that Mobil Oil is a mineral. Told me to use a synthetic oil because this will give my bike back problem, but Honda says in the manual that if you use another oil loses the guarantee, but not the mechanical one, believe that mineral oil.
The bike is still allowed in the workshop, and frankly, I've had 3 R1's just walk on track and never have problem, CBR 1000RR 2008 is very weak and do not know if that will endure use in track.
