What about valve clearance settings? Should I go tighter that book settings?
The factory service manual spec is good.Not in my view .. Stock is good .. Please check so there is play and within specs
Not sure what book we are talking about here
There are service manuals there where values can be found

I thought I saw a thread where someone was using a KTM filter similar to this one:

Not sure what is involved, but probably more than I'm capable of. Seems like a sturdy filter element but not sure what's needed to convert.
