    so i fitted some 3.45 gears recently and now my speedo is about 11km/h out. does anybody know how to correct this. it's a little annoying when i seem to be speeding all the time

    just finished soldering my kit together, now to read the instructions and figure out how to make it work. can't be to difficult.

    have taken some pics, so i'll think i'll do a "how-to" for fitting a speedo correction kit to the VN/VP, where to find the speedo circuit etc and settings for the kit once i figure it all out
