my 05 I call her Matilda, has been a night mare. had to replace the speedo cable, the air filter ( and lost the snorkel). the air injection trash is still on the shelf ( it will not throw its self in the bin). had to put in bigger main jets and shim up the needle. I also had to throw those 30 lbs junk stock slash cut silencers away and replace them with some very light wieght 18" turndowns. Now i still keep changing things.
