I have a completely stock 06 600 and am looking to eliminate the throttle jerkiness that seems apparent in the 600's that I have ridden. I took the bike to the stealership and they adjusted most of the freeplay out of the cable and it has seemed to help. I am considering the R1 throttle tube mod as I just got my new grips in and figured it would be a perfect time to do it. In addition I have read some posts about using the Power Commander, but I didnt know how much difference it would make on a stock bike. Thanks in advance for your suggestions.
