Yeah. It's the valve train right as the different thermal expansions give it it's greatest clearances. As it heats up some more the clearances close back up.

I hate doing valve adjustments. So in my never ending quest to use modern technology to validate my laziness, I've been running the Liquid Moly lube in the engine since new. It's been about as abused as an engine can be, short of rev limiter burnouts. Done a lot of hot slow running 2 up on forest tracks in 35 ~ 40 degree C. A lot of "trail bike" stuff. Way outside the design brief.

So far so good...right?

What have the valve adjustments been like over that period? What I'm looking for is are they running relatively the same sort of interval between adjustments or does the interval get shorter as the kms get higher? (indicating a bit of valve recession maybe). 

I'm at 30,000kms now, and in the transition from cold engine to operating temp there's a point about half way through warm up where they get a little noisy, but at operating temp they're quiet. I got 90,000kms out of my BMW (F800 with the Rotax engine) without ever touching the valves, and so far this seems to be going the same way.


I asked my dealer and this is the anwer



Between 200 and 300k intake valves front and rear have been adjusted once (not by much, only 1 shim size). every 24k, 1 or 2 exhaust rockers "have to" be adjusted but that is just nitpicking

Thanks mate. I'll have to schedule a top end check....just as soon as I clean out enough space in the shed to have room to swing a ratchet. Son keeps buying bikes and storing them in my shed. 5 of them so far...well...4 and a half...may as well be 5.

A friend has 4 BMWs in there as well while he's rebuilding his house. Plus my bikes. Hard to find space to fit the lawn mower at the moment.

my bike did 100k without valve checks. after 100k al inlet in spec, exhaust needed adjustig. Gap was <0.3 but not a lot.
Bike did commuting and travel mostly. With abuse every 25k is wise i think.

There are better bikes for abusive behavior though :164:
