Argh!
Got it done but that valve clearance check is pure:evil !
Hours of work to find out that something is actually fine! :\
Oh well, at least it's only every 25K!
I'll suspect there are rather a lot of owners who will never check them, myself included (84,000 miles up and not checked). Most mechanics will tell you that these 5 valve Yamaha heads will stay in service for the life of most of the bikes.
I read that there's some women in the States who had her first check at something over 200,000 miles and just one valve was on the cusp of needing a reshim. Impressive.
That is impressive. My take on these is that if they are in spec, they are in spec. I never change if in spec even if others want it in the middle of spec range. It could stay within spec for a lot more years and it is IN SPEC ?
