sweating oil while driving MT 350.

Post by fedrico » Mon May 25, 2020 10:57 am

When i drive my MT 350 oil is sweating a little bit on the site of the gear lever. When put the MT 350 in my cellar an i clean it, there is no oil swaeting on the site of the gear lever.
What can be the cause of this?

Check the seals around the kick start mechanism, and on the gear selector.
It could also be a damaged clutch casing gasket, or you may even have a cracked casing in that area.

My dealer saw some damage on outside (bottom side, looks like a small tears)of the timing belt cover, so i have ordered a new one with a new gasket. Maybe this is the cause of the sweating of the oil while i am riding.

Ain't there an O-ring as well?

It might be migrating from cambelt cover but you'll see evidence of it.

It could be clutch cover has worn through/cracked at kick start.

I'd start with easiest and go for seal around kick start, gear lever.

Is your breather hole clear ? Lardmarc recently posted a photo so that you can see where it is

As mentioned in earlier posts , O Rings should be replaced. A good bike dealer should know this

Have you tried running with your oil level lower than maximum ?

sounds like the oil seal on the kickstart shaft, I have a similar issue on my 350 which has become a bit incontinent and thats the prime suspect , and I need to pull it apart and sort that out . There are o rings on the kickstart and the gear lever shaft worth renewing .
best thing is to thoroughly clean the engine with clean rags then run it and it should be clear where the oil leak is coming from

The cambelt cover should not have any build up of oil behind it ,it ought to be quite dry in there, if there is oil around then an oil seal has possibly failed on one of those shafts

There is no oil sweating on the site of the gear lever.

I reckon that translates as no oil leaking around gear lever.

I'm going with that.

I had contact with Force Motorcycles about the oil sweating while driving my MT 350. He thinks it is the oil seal of the bottom timing pulley that is sweating oil. So i also with fit a new seal on the bottom timing pulley

Check for slop in that bearing, if it moves under pressure then it's a sign your main bearings are about to fail, a weeping oil seal is often the first sign of this in that area.
