    Default lRear drive belt 84 FLH Shovelhead 4spd

    Whats up...new here on posting. hope im in correct section....Anyways i have 84 flh shovelhead w 4spd ...STOCK WAS 126T, 70T REAR 32T FRONT......i Have a rear pulley 65T and my front pulley is a 32t or 34t not really sure yet. But id like to order belt for it online because its less expensive for same belt to buy anywhere i live.....My question is when i do the formula for 32t it comes to 125.8 T and 34T comes out to be 126.8T. Cant i just get a 126T or do i have to take everything off first and count the teeth on front pulley.






    21inches which is the centers of front pulley to rear...converts to 533.4mm
    FORMULA SAYS
    533.4X2=1066.8
    1066.8/13.8=77.3
    THEN ADD 32T+65T=97T
    97/2=48.5
    48.5+77.3=125.8T


    533.4X2=1066.8
    1066.8/13.8=77.3
    34T+65T=99T
    99T/2=49.5
    49.5T+77.3T=126.8T

    2nd?

    what is the largest front pulley i can use for my bike. my 4spd rpms just way to high sound wise for my liking...really like to put a 6into4 but little pricey....Anyone have a 5spd used? believe 84 fxe or fxd or whatever came standard 5spd but flh was a 4spd standard...sucks...

    5 speed doesn't have overdrive in 5th, so it won't drop your rpm. You maybe able to drop RPM with pulley change.

    For a four speed, I think you are stuck with the stock transmission pulley. I don't think anyone is making anything else. (Five speed pulley won't fit.)
