Hi NordieBoy,
I saw your hint somewhere else (...) and investigated and went shopping immediatly.
The parts allready have arrived. I will swap out the front sprocket on the Tenere in a few days.
Thanks for that!

The Mini-Ten is spitting oil out the case breather all the time. Worn rings?
The engine is also a bit rattly until 5,500rpm or so.

The rings have got over 300hrs on them.

Hmmm, the engine was rebuilt before I got it, wonder if there's a baffle under the breather that was missed out...

Blocked oil ways can cause oil to spew out the breather apparently.

A compression test should give an idea of how good your rings are.

Now this might be a dumbass question, but is a compression test do-able with the auto decomp hooked up or should it be removed prior to doing the test?

Nothing dumb about asking a question Jimmie, i personally would unhook the cable from the side of the head before doing it.

Mezo.

My manual gives a compression figure & says do a compression test in the normal way, hold the throttle open & spin the engine over. But I suspect whoever wrote the manual forgot about the "AUTO" de-comp, the XTZ660 manual is wrong in other areas.

I think you need to lock the de-comp mechanism some how before you test, depends on how the auto de-comp works. If I removed mine I think I would have to seal the end of the cam as well to keep oil pressure

Is the 350 auto or manual de-comp?

External cable from kick start to front of head.
