imexian Posted May 16, 2013 Report Share Posted May 16, 2013 Hi, Will a reed valve 305 motor fit straight in a 300 frame? Regards, Ian Quote Link to comment Share on other sites More sharing options...
ask greeves Posted May 17, 2013 Report Share Posted May 17, 2013 Hello Ian, straight in fit, you'll need the 305 exhaust, first inch or so, to replace the same on the 300 exhaust, the head steady may need modifying slightly to fit the 305 engine, and the carb rubber (carb to airbox) will need slight tweek. Hope the 305 engine's a good-un, pistons distort and become noisey and new pistons are becoming rare. Quote Link to comment Share on other sites More sharing options...
