I had an RD350 in high school. Damn thing was a pita to get started ad I didn't know enough about bikes to really get into it. It would burble and pop until the tach hit 7k, then turn into a rocket.
I had the RZ in HS. Wheelies galore, poor bike. I didn't know any better at 16 and maintained poorly. Bad deal.for guy that bought it.
ZZ Top was my favorite powerband
This is why we don't have two stroke bikes anymore. Too many squids.
On the flip side, it doesn't really matter how thrashed the motor was/is, I can rebuild a Yamaha twin 2T engine, including rebuilding the crank, new bearings, new rings and pistons, rebore, deck the head, in an afternoon, which I guess would include a new power band, costs ME about $500.
I have actually done most of that in the pits, between rounds, a couple of times... in one weekend.
Ya gotta love two strokes.
REAL MEN don't need more than two strokes.
Valves work GREAT in toilets.
More than two strokes, you're playin with it
