Just finished installing a Mikuni HSR 42 "easy kit" on my M2. It was the smoothest installation job imaginable. The instructions were complete and easy to follow. The hardest part of the job was shortening an allen wrench so I could remove the stock air box. When the carb was installed, it started immediately, idled smoothly, and ran great with no adjustments other than idle speed. Tomorrow I plan to check needle position and main jet size but, even if changes are needed, it will be a simple job to dial in. I wasn't sure if it would be worth the time and cost to change to the Mikuni but so far, it looks like it is. Does anyone else have this carb installed on an M2? If so, what main jets and needle are you using? Any information/advice would be appreciated. Regards, Dave | ||

Dave, I installed one on my m2 back when i had it. I don't remember the main size but the ones that came with it were in increments of 5. if memory recalls me they were 40 and 45. One was too lean and one was too fat so I had to order a whole pack of 42.5s. I have a bunch left. If you need one let me know by pm and i'll drop it in the mail. I'll check the size for you when I get back home to be sure. The needle was adjustable by the e clip if i remember and i think i was running it two up from the bottom end. I also had the buell supper trap exhaust and the buell carbon fiber race intake. I was also running it in South Georgia. Don't know if any of this was helpful. John | ||

I've got one on my S2, it's one of the best investments I've ever made! Congrats! | ||

I've got an '02 M2 pretty much stock. What are the advantages of this carb over the stock one? I was checking them out on American Sportbike and was about to ask here before purchasing.....So whats the deal? More power? Better mileage? both? Thx (Message edited by Igneroid on October 06, 2007) | ||

Neither. Much better (crisp, immediate) throttle response, plain and simple. On an M2, I doubt you'd see any more top end power. But how it feels getting there is all the difference in the world. Al | ||

Sorry I was wrong about the numbers. It was a 162.5 main jet that I have extras of. John | ||

John, The 162.5 jet came in the mail. It seems to be the optimum size for my M2. The bike runs great. Many thanks for your assistance. Regards, Dave | ||

"Much better (crisp, immediate) throttle response, plain and simple." You wouldn't think this would be such a big thing, but the sharper response is really noticeable. I don't have one (yet) on my M2, but I was impressed when I rode a flat slide equipped S1. The response isn't too sharp during small throttle openings (like a CV can be) and it's not mushy at big openings (like a CV can be). | ||

John, I could use one of the jets also. If you have one to spare. I'm sending you a PM. Brad (Message edited by bluzm2 on October 26, 2007) |
