Have a question regarding my standard mc28 only revving to 10,500 rpm. Bike is standard and mint with low miles and goes through power band nicely but doesn't really want to go past 10,500, I'm not a mechanic but have owned an mc18 and mc21 before and these being standard as well revved nicely all the way round. I know the mc28 is the hardest to make full power so is this rev limit normal on a standard mc28? Appreciate any help on this. Thanks. Henry.
