Re: Is it time to extend out valve clearance checks?
Thanks y'all for the various insights and opinions.
In light of the fact the every 12K checks have all been well w/in spec now at 38K miles, and that I don't ride the bike super hard, I think I can live with every 18K mile checks which jive w/ my oil change interval which is right about 4,500m. There appears to be an inverse relationship in how difficult (or expensive) the procedure is versus what the recommended valve clearance check interval ends up being. For example, I know my bro's former 4 cylinder FJR's recommended check was every 26K miles. How come? Better manufacturing process over BMW? K1600 I think is every 18K miles. How come? Why not 12K miles? Modern car engines? Never. This suggests to me the real risks involved with not checking, which should be a metric that should be independent of the cost of the procedure, is ultimately very low. I read countless tales of people with high mileage machines that never find a valve out of spec. And I have read the odd story of finding a valve out of spec or closed all the time, but to no major avail either, i.e., no apparent detriment.
Anyway, cheers ride safe and thanks again.
