greasy under swingarm

[minivin]

evening all

just been giving the bike a wash down due to all the salt, aint done it for a few days as got lazy when I normally clean it each night.

Anyhow, got checking under the swingarm for dirt and found a black patch atthe back where the wheel pivot box joint is, swiped my finger over it and it was very sticky, followed it forward and it also under the suspension strut mounting point and at the front....... but none has made it to the sides or on top. Smells very much like transmission oil rather than engine.

Sounds a bit sus to me....... any ideas?

Copied this also to Wally down CW motorcycles as the bike is still in warrenty

Rob - because tranny oil has such a distinctive aroma I'd reckon that's what it must be. Is there any weeping from the gearbox/main engine unit join, especially on the rhs? It often does so and tracks down to the 'fins' at the bottom, just to the rear and below the cylinder.

yup, dfinately smelt very much like transmission fluid, the clutch has been faultless recently so from the middle of the gearbox forward is good, had a quick look under the gearbox and nothing too obvoius but will have a look in the light tomorrow.

hopefully it isn't too un-toward as it's only done 10,000 miles

ahhhh, after a closer look in the daylight, we find that it's just dust at the front end while the only concentration is around the rear diff dust seal, will give it a degrease and see what comes back

Seal at bevelbox very often fails.This is a warranty job.Not for the faint hearted as you will need a special tool to remove the castle nut from the input shaft in the bevelbox.
