Just got the lad a Beta 80 and set about changing the gear oil as it looked a bit dirty and I wanted a piece of mind.The guy I bought it off gave me some YAMALUBE OIL that he said he has used in the gearbox for last 2 years or so.I drained the oil and put in the 300 ml as per manual but upon starting and testing the bike in gear it appears that the bike is still driving a little even when the clutch is fully pulled in.

Could it be thatr the oil is incorrect or is rthis a common fault and is there an adjustment that can be made or will other oil solve the problem? thanks in anticipation.

We used silkalean light gear oil never had a problem with clutch dragging.

i use atf in the daughters with no problems

Does it normally need bleeding after replacing gear oil?

no very straight foreward
