I took my scoot's cylinder to work and checked the bore. It’s still within spec.
I had a hell of a time getting the head bolts loose. Had to take to Timo’s place and use his 3/4 drive impact. That only got two off. It took a breaker bar with a 4 foot cheater bar and Timo on the end of it with the bike tied down in my truck.
Since the cylinder is good, I’m just going to put a new piston and rings in. But, Holy Crap!
I just priced the parts, and a piston kit and gaskets is $321 at RMATV. That’s a lot more than I was expecting. Furkin’ KTM
I will say, though, that it’s holding up a lot better than my last red bike.
