my 1985 wide glide with a 4 speed, evo engine, belt drive.
Ronnnies web part book says the part number for the front pulley is 40212-80D. Does that seem right?
Is this 33 tooth pulley?
is the rear pulley a 70 tooth?
is the belt a 139 tooth?
where do suggest I buy a front pulley? Not too expensive
Thanks for you help

 

There are various places we can check part numbers, my preference at present being Five Seasons, which confirms that part number. IMHO it is most likely to be a 32T, which seems to have been standard on big twin Harleys since they introduced belt drive. Can't confirm the number of teeth on the belt, although 139T is common. All this should be in your FSM!

 

Not exactly sure on the belt but you are correct on the pulleys.. I would find a gear ratio calculator to determine what gear you want before purchasing and go to the BDL website to determine your length for the belt.. thay have a chart. A 3.28:1 overall ratio would be the highest you would want to go on 4 speed..
