When I first start my 99 wr 400 the clutch is grabby and not smooth. I let it warm up for about a minute or 2. Is this not long enough? The tempture here is usally between 45 and 60. I have mobil 1 synthetic red cap from walmart in the crankcase. Could this be why ? It only happens the first time I let out the clutch. Is it just becouse the plates have no oil on them yet? Just wondering if its normal?
