I just discovered I've got a 22 tooth sprocket on the tranny of my Pan. The bike has an 11mm BDL belt drive and mechanical brake drum (51 tooth). It has the kicker 4-speed (36-***** stamped) and I have no reason to believe the gearing inside is anything other than era factory ratio.

While I have it apart I am debating on changing that sprocket out for a 23 or 24 tooth to improve highway speed.

Not sure if the 11mm BDL increases or decreases drive ratio over stock as it is. I've got a 100 link chain on the bike now and the rear wheel has to sit towards the back of the adjuster area to get the chain free play right so in the previous thread John hit it right on the money...sure enough a 22.

Now I haven't ridden the bike yet so I don't have a baseline on the gearing w/belt drive now, but I'd like to change the sprocket while its apart if it going to improve the ride.

Any suggestions on what do to...keep the 22, go with a 23, or even up to a 24 or 25? Looks like it's going to be a pain in the *** to get the sprocket off but if it's worth it to change, then I'm down for the cause.

 

22 tooth is side car gearing dresser

23 is dresser gearing

24 is FX or chopper - bobber gearing

25 you might not have enough motor tuning experence to use as the motor has to be right on and very close to stock and in very good engine condition // OR a stroker with a cam to power over the overdrive gearing < if your going to be at 75 all day yea

 

24 it is then....it's a bobber, it's light, the motor runs good but it's tired.

I just want to get and close to or go the speed limit in my neck of the woods....65 or 70 for the most part.

Thanks.
