Hi all,
Here's one for the mechanics out there.
My ST4S has started to breath a little oil, such that when I stop after a spirited ride I get a small puddle of oil under the airbox breather.
Its just had its 36k service, and a number of the clearances were out. I was told that this can cause them to breath heavy. I took this with a pinch of salt but apparently the mechanic was told this by two sources (baines and protwins).
I've not ridden it too far since the service, so can't say if the clearances have helped. Will know soon enough though as we're off to the Alps on it on Sunday...
He checked both compressions and they are fine.
Apparently the air filter was very dirty, not sure how that would make a difference though.
It just sounds odd to me that valve clearances could cause heavy breathing (from the engine
)
Any ideas ?
Cheers,
John.
