Hi All, I'm new to the group.A former 34 year mechanic/service manager for local Suzuki dealer-now with a independent shop of my own. There is (as of this date)no recall on the busa starter clutches. The problem seems to occur under certain conditions,(1)high heat-low battery charge;(2)poor quaility gasoline;(3) opening of the throttle while starting the engine;and (4)high compression(above 11:1)and/or big bore pistons.Suzuki Service Bulletin GS/GSX/GSX-R No.126 dated 12-10-02 shows the Interchange Info between the 03 and earlier models.The 03 starter clutches are not interchangeable with earlier models,but the rest of the starter parts are,if you want to buy a 03 starter motor,03 starter idle gear limiter,03 limiter pin,03 starter clutch cover,cap and gasket.I have built 7 - 1397cc;13:1 CR;.395/.378 cam and bored throttle body(48mm)engines to date.Each is using the stock starter motor and starter clutch.Starter mods include the heavy duty starter gear(APE) and GSTX12-BS battery with AWG 4 wiring from battery to starter relay to starter motor and AWG 4 cable from engine ground(at the starter motor) to the battery negative terminal. The stock wiring is IMHO to small to give full amps to the starter motor in high engine heat conditions,which cause the engine to spin over to slowly and invites the kick-back that causes the starter damage.Stock engines benefit from the wiring change and larger battery.Also,not opening the throttle when trying to start the engine in high engine heat coditions(stock or modified)greatly reduces/eliminates the chance of engine/starter kick-back .Suzuki will warranty any starter problem,if the bike is still under warranty and the dealer can verify the problem.If the bike is just out of warranty,a good customer atitude and a caring service manager can get Suzuki to "Good Will" warranty the problem.Calling Suzuki directly and complaining loudly does nothing to help your problem and can in fact slow the process as that gets others in to the loop which slows down/stops the process.Go to your dealer as Suzuki prefers it this way.If your dealer is crap,find one who cares,they are out there. I hope this can help. Louis..
