I'm going to change my valve seals without removing the cylinder head. I was going to stuff the bore with some small rope and use one of those tools to remove the springs and collets. A Sealey VS1542 valve collet remover.
Anyone ever try this method? Is there enough room to do it?
The bike is a 4TX with 10,000, uses quite a bit of oil in my opinion.
It could be glazed cylinder bores, but I think hardened valve stem seals is a good one to eliminate first. ... and I can check the valve clearances while I'm in there.
I don't think it's leaking from any engine seals.
