Hey guys have just finshed swapping my oem  32 tooth trans pulley for a baker 30 tooth. I just need to re-calibrate the speedo. Have got a little gismo from dakota digital to do this--lucky me the 07 is the only one that this has to be hard wired in the other models are plug and go. Just a quick blast up the highway and  I can fell the difference. its quicker off the mark and obviously revs a bit higher in top. I should be able to drop it into 6th now at around 110 kph with out lugging the old girl. Once ive done the calibration ill be able to let you know what ive gained and lost. Ill let you know what the change over cost in parts and piss---cheers Grim

G'day Grim. Iam keen to hear about the parts and process. I have an 08RKC that I have been thinking of doing. Was there an option on how many teeth you can have. For an instance is there a 31 tooth gear I could use. I was hoping to use the same belt if I only changed do one tooth. By the was the TTS can change the final drive ratio to keep the speedo correct. No doubt we will hear more.

Hey hey Fr3d, will keep you posted-there was a range of different toothed pulley. a 31 tooth was an option. When I looked at the pulleys from baker they suggested a 30 or 31 may require a belt change. I went with a one tooth shorter belt. If you do go the the 31 tooth i would tension the original belt before you put the inner and outer primary back on incase you find you need to replace belt
cheers Grim
