Picked up a used RC51 from middleboro in late may, got it on the road early June. I have about 800 miles on it so far. I use it to commute to Worcester for work a lot.
I love the thing to pieces. Needs a little work, but thats okay.
So far I put stock bar ends back on (none when I got it), but the center stem cap on, changed the oil, changed the blinkers from blue to amber, tightened the chain a ton, ne exhaust gasket, and I have a read LED brakelight on order, which actually should be in today.
Its got m4 cans and a fuel commander.
It needs a new chain and sprockets, and a radiator flush. I want to do the chain myself, but Ill need a stand and a chain breaker/rivet tool, so its gonna cost me. i think I will hold off until this winter for $$$ reasons, but I am not too happy with how the chain looks.
