Looking to buy a gt650. Bike appears complete but engine is stripped. Don't know what the original problem was but for starters , engine was stripped and parts left in the rain, barrels are rusted and will need a rebore and a set of oversized pistons. Local dealers only keep std pistons. Before I buy the bike I would like to know if parts, prices and info is available to make an informed decision. All and any info is appreciated guys.
