Based on what you say id put a price on it of $2500-3500. Depends on alot of things. Ignition, clutch, clutch basket, crank, brand of bearings and gaskets, and also condition interior and exterior. Powder and polish condition. We need pictures and more details. BTY I'll testify that BDT puts out very strong motors. Im running a sphinx 363 from them right now and it is great runner. No problems at all.
