Well, I just turned 70 this past December and intend to keep riding as long as I can hold up the bike.

I had an issue with a full sump of fuel but I had already done the raptor so...
It turned out to be the seal on the float valve body in the carb. A few wraps of teflon tape fixed the problem. That was about 8 yrs ago. No problem since.
A rather strange problem, wouldn't you say?
