has anyone out there changed the gearing on a 07 sporty to make it better on the highway ?.

Is your bike a 883 or 1200 ?

883

You can fit a 1200 Front Pulley on and you will pick up more top end

do you know how many teeth the 1200 front pulley would be ?.

hi, the 1200 pulley is 29t   2 teeth up on 883  27t , olso fits same rear belt , cheers

sorry , i stuffed-up  on  pre 04  883 is 27t & 1200 is 29t , on 04 later 883 is 28t & 1200 is 30t  i think the belts are 1 tooth differ 136t/137t  ,  cheers i will know more next week as i am doing  a 04  & a 07  883  to 30t pulley set-up  cheers

hi, just done a 06 model sporty 883 front pulley was a 28t brought original 30t off a 1200 sporty, $110 easy swap, rear belt adjustment on the rear axle in the swing-arm went from from just before the rear of the centre of adjustment to the 1/4 front middle of the adjustment range still using the stock 883 rear belt .
the harley bar & sheild on the belt is pepermint green on 1200 & on the 883 its orange colour . it could be 1 tooth differ as differ colour bar & shield for differant belts on stock bikes , cheers

Did you have any trouble undoing the  1 3/4 inch nut on the shaft? I know it is reverse thread but I had to abourt as even with breaker bar could not loosen it. What tools did you use to undo yours, cheers.

hi, i use a small air rattle gun only to un doing the left hand thread , it has loctite on it so it is on hard  because they can come loose because the pulley is so heavy , cheers

Thanks daddyracer will give it a try. I suppose the rattling effect is what does it. I even fabricated a locking device so the sprocket wouldn't move. Veeery tight indeed! (just how we like em LOL)

hi,i adjust the back wheel tension up a bit  untill it's just -on firm (no slack ) & hold the back brake on at the same time as you undo it  if it's too tight,    put it into top gear also with the back brake on ,     cheers

Thanks again.
