Thought I would report that after having the valves checked with 45,000 miles, all were in spec. and have never been adjusted.
Very sweet!

That's good to hear, as mine has done 35000 + and I'm pretty sure they haven't been touched either. My motor sounds real sweet and quiet, so I'm leaving mine for a while longer.
Yup,mine were in spec at 40-ish-k klm too
will check again at 100k klm/63k miles
all my intakes were at .004 at 40K miles
and two exhaust were out....I'd have to look at what I wrote.
damned thing runs like a raped Ape....oh, wait, it IS a raped Ape
Rotax makes aeropower plants as well.
Yup,Rotax are tough as...
BTW,RH inlet on the rear pot was
at the lower end of the specs at just
over .12mm but I'm not worried.
Many motors run much closer than this
especially in California where they make
some aircooled Guzzis run half the normal spec!
That's the best possible outcome. I've had to adjust three valve shims in 60,000 miles, but the reason was odd. The clearance had opened up a bit, so I calculated the shim required to get back into specs. When I installed the new shim, the valve was too tight. As it turned out, the original shim had been dimpled by the valve stem, which is smaller diameter than the shim. So measuring the shim with a micrometer didn't show the thickness actually "seen" by the engine. Installing a new shim of the original size put the clearance back in specs. I don't know why those shims were dimpled. Maybe they weren't properly hardened. Regardless, I tossed them out rather than attempting to flip them over and reuse them.Originally Posted by Capsil21
