As for mine, its a Stage II 95" MM injected Stage II big bore with about 85 HP and 95 Ft/Lbs TQ, I just passed 150,000 miles on the motor (I did install new heads back at 75,000 miles,) and the bike still runs excellently which speaks a lot to its reliability.

Just a suggestion, if it hasn't been done yet look at changing your fuel lines to the goodridge lines. My factory lines (not rebuildable but the goodridge ones are), were driving me crazy, leak one minute, then wouldn't have any issues for a month, then dump a gallon of gas everywhere, then wont leak for another month...... Best $150 I have spent on the bike. Fuel leaks will drive that MM crazy.

Mine is an EVO, and when it is tired I want to build a 89" for it. Keep us posted on how it works out!

I've thought about upgrading the injectors but I can't find them anywhere. I have the red ones, but I've heard the green ones work better. My MM works amazing at the moment. I was just concerned if hamper the results of my build, but according to most on this thread it won't be an issue at all. Thanks for the input.

Any ideas on the injectors?
