Greasy Final drive

Hi Guys

Got back last night from a 3 day 2100 mile trip. Noticed this morning a film of oil over the swingarm, final drive and rear wheel. Basically everything back of the passenger pegs.

Will swing by the dealer tomorrow. Prefer to go armed with some info - any idea of the cause?

FWIW was a high speed trip - averaged 75 mph including stops, and the last 600 miles was in a torrential downpour.

Thanks

Look where it starts to get oily... problem is forward of that point.. If it originates at the rubber boot I would expect a seal in the swingarm.. If the swingarm boot itself is oily I would suspect a transmission or engine seal. See if you can determine from underneath how high it goes... You can also check your gearbox and engine oil and see if either is low... or up to level... if both are at the correct level you may have unknowingly hit an oily patch on the road.. If both are up to level.. you need to clean everything up and pay attention as you ride.

The seal at the front of the final drive can sometimes leak, as well as the seal at the rear of the transmission. Yours may be a tranny seal since the front of the swingarm is also dirty.

They should be able to determine the cause and swap out the seal pretty easily.

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

Checked oil level - has moved from top of sight glass to the middle.
Does not usually use oil between services, so most likely an engine seal.

The LT does not, as a general rule, use any oil. With your bike on the sidestand, the oil level should be halfway on the site glass. On the center stand, it should be at the top of the site glass. It is best to leave the bike sit for a time before checking the oil.

Should have made myself clearer - I did check it before the trip on the centrestand - was almost at the top. On return was a hair above the middle.
