Alright, I m looking at buying a 83 250r for 1100. it has dg exhaust, boyesen power reeds, k&n air filter, douglas rims, razors on rear, pro taper handle bars, and new rear plastics. Saw it today starts good looks decent, but it has an oil leak from the drive sprocket, and the rear shock is blown(although it seems to be just low on fluid). he also says it has a smaller jet in the carb as to limit the power. All in all would this be a clean deal, and how hard would it be to fix the afore mentioned problems. Thank you
