looking for a 4 inch. pulley to go on the crank of 1200 1984

That's the part I haven't yet settled on for the day I do mine.

I have the alternator (but I have a good stator too) and it has a small 1/2" V -pulley. The 3 groove pulleys were I guess the year after miy alternator is for? I do have a 4" 1/2" wide V -pulley that's steel and welded to a hub with a 5/8" bore from TSC that would need to be bushed to fit the new longer crank bolt if I use it.

Anyway .... once I settle on a pulley .... I may take a fit and just do it? No rush .... but watching closely!

For my conversion I used a pulley from a power steering pump out of a 93 Toyota Camry. Had to buy the whole pump from the salvage yard just to get the pulley. The pulley measures about 4 and 1/4 inches in diameter, and it would allow you to use a serpentine belt with the alternator.

On my conversion I used the power steering pump pulley from a 89 Honda Prelude. If you know a good machinist then you can have them cut you one using this drawing

hope this helps

Has anybody tried Grainger?

A 3.5 inch pulley is what you need, everything will fit better.

i just finished mine, and hope to have pics up soon. i now have 5000 miles on new conversion. i built my pully by taking a idler pulley, removing bearing welding in a center and mounting it... unfortunately wasn't perfect so i now have a bit of vibration @ 3300 rpm.. just a little. love the conversion! getting ready to forge and machine an aluminum one, may consider making more.. don't think it will cost me too much.

Over on NW site fellow mounted his alternator. in the center of the bike in front of the airbox. He used a pulley from TS or HF no machineing fits tighter to engine than the ones used in
poorboy. seemed really simple. Just bolted the pulley to front of crank and used a keyay cut in bot to stop it from backing out.
