Looking very nice! It's been warm here too, but I'm waiting on a crank case body to perform a rebuild on my 66cc. I should have taken other's advice and used a helicoil, I'd still be on the road!
coming from a top notch bike builder like you with a kazillion builds under your belt makes me feel special.
i know i'll never recover the $$ i put in.
the joy i got out of the time building it, the joy i get outta driving it and the grin i get outta looking at it made it worthwhile...
