Quote:at what point(mileage or otherwise) would you suggest physically/visually checking this measurement ?
This is just my opinion based on reading most of the cam-chain posts on the forum, and my experience with one bike.
On a bike bought new I think it would be safe to go 15,000 miles or so before taking a look assuming the engine dosen't suddenly start to rattle.
On a used bike,especially one that you don't know how it was maintained by the previous owner or owners, I'd take a look sooner.
Like I said in my previous post the plunger on mine was out 16mm at 10,000. I likely could have ridden like that for another few thousand miles before doing anything but I decided to put the modified adjuster in while the bike was down for the winter anyway instead of waiting.
It's not that big of a deal to take the cover off and look. verslagen1 has excellent instructions in the tech section. I didn't even have to replace the gasket. It stayed stuck to the case and the cover came off clean. A little Hondabond around the oil passages was all I needed when I put it back together.
Even if I had pulled the cover a found that I didn't need to do anything,I figured the work was worth the trouble just for peace of mind.
