I have a 1990 250r in need of a new exhaust system. I notice Mussarri have a full exhaust system including mid pipes and mufflers specifically for the 250r at a very reasonable price on eBay. They state that retuning is not necessary with this system.

Does anyone know from experience if this is true? If retuning is necessary Ill simply get a second hand original set as I can’t be bothered with taking the carbs off a dozen times to never really get the jetting right.

I should add that the bike runs perfectly with the tatty but original exhaust system!
