oil leak Rotax 500

[JulianMZRotax]

Hi

The bike has started to leak oil from the clutch cable bellows cover . It only started after a fast run . 33900KM . Oil change and new filter August last year . semi synthic oil used . Have checked the enging breather pipe and this is clear .

Any ideas ?

mine leaks from this area when ran hard ( it has 19,000km on it)
there is a rubber o-ring on some of the clutch cables where it seats in the case that may be bad or is a cable with none
and mine has a rubber boot also in this area

i am not a fan of the simi syn oils some are too slick and will ruin the clutch
fiber plates

i use shell rotella T 20w-50 oil

my dad always said "if it does not leak some where it must be out of oil "
but then i think it was a BSA he was talking about

ps there is a hose on top the motor to the frame tank this should be checked
and renewed as it is a major pain in the A to change on a trip ...on mine
the gas tank must be removed to get too it
poor design results in the fuel shut off having to be removed
to get the tank off even after draining it dry there is still a bunch of gas in the tank..the job best done outside with care
