Dripping Goo

adam.peat74 · 09-24-2008

I've a treasured KMX125 b10, 8yrs old now with 20k on the clock.
in the last few weeks i'm getting a lot of oil coming form the exhaust and i think more smoke than usual (although its always pretty somkey

)

Possibly feeling lower power in low revs also although once going she's alright.
I've checked the oil pump adjustment and that is as it should be.
the bike has a big one expansion, and a production silencer (used to be DEP but too noisey for where i'm riding)

what else is worth looking at?

thanks.

Check your sparkplug.

Check the compression, has the engine ever been rebuilt?, 20k is a fair bit even for these road engines! Sounds like the rings are in need of renewal or even better, a full rebuild then if you use high quality parts it won't want doing for another 20k.

Just read my manual, the service period for the 125s top end is every 17500 miles and a full rebuild at 30000 miles.

the plug is a bit sooty but not oily, was replaced approx 3k ago.
