hey, since im new to this bike i dont know much about prices. how much would another 750 run me? i tried turning my motor over for the first time. primed the carbs,tuned them, made sure all the fluids are good battery is good all im getting is a funny clunking noise and this motor never has turned on for me so im guessing something internally is broken, im way to lazy to get into all that stuff. neither do i have the spare time. all in all, how much would another 87 750cc v4 go for? in decent condition.
