Water in Gearbox

[big unit]

Does anyone know why when riding in the wet, rainwater can enter the gearbox.

How can this be prevented.

Cheers.

Hiya,

 

Yep, this is a common problem. The source is the transmission breather on the rear of the case, that is exposed to directed water spray from the rear tire.

 

One solution is to build a small triangular plastic fender insert, and mount it in the front trellis of the swingarm, as illustrated at:

 

Forum Inner Fender Modification Thread

 

Other solutions suggested before include changing out the breather to another type, or modifying the cap on the breather to accept a remote hose.

 

So far though, I think the fender modification has worked well enough for most folks.

 

Hope that helps

Thanks Al, your post is of great help.

I am personally going to come up with a nice hose extension for the breather due to the fact that the gear lube has a tendincy to dribble out under hard acceloration or during wheelies I think I also need a Dictionary

 

Hope this helps.......Jeff H.
