getting ready to do the 30/70 conversion
Hey, so i'm just getting the pieces together to do the 30t/70t conversion on my breakout, i've found a WICKED deal on an arlen ness contrast cut 70t pulley 1-1/8" 70t. so it'll be coming in the next week.
what else do I need for sure? my check list is as follows:
rear pulley spacer, 3/8"
rear pulley bolts
derby cover gasket
primary cover gasket
front pulley.
oil
anything else I am missing?
I'm also putting in a shift light at the same time, so that will have wiring run to pin 3? of the ECM
also, while i'm on the topic, derby and timing covers, they are all more or less interchangeable right? the only issue is bolt numbers?
basically all 5 bolt covers will fit all bikes which had a 5 hole?
this is the one i'm looking at:
https://www.ebay.com/itm/Timer-Timing-Cover-Derby-Cover-CNC-Motorcycle-Fit-For-Harley-1999-2014-Twin-Cam/192510502462?_trkparms=aid%3D111001%26algo%3DREC.S EED%26ao%3D1%26asc%3D20160908105057%26meid%3Dce5a0 e86d45a456391b74ed7d8dcd428%26pid%3D100675%26rk%3D 1%26rkt%3D15%26sd%3D192510502462%26itm%3D192510502 462&_trksid=p2481888.c100675.m4236&_trkparms=pagec i%3A966b04c6-9523-11e8-ad99-74dbd1809d05%7Cparentrq%3Af2ee76061640aa14483b9bb8 ffebb86e%7Ciid%3A1
also, for the front pulley, are they all the same, with the exception of the tooth count? can I use one from a sportster or street? there's some great deals on pulleys off of sportsters and streets, they look right, but I have no idea.

I've been looking, found a few 30t pulleys for $50 but I can't find any parts compatibility info on them. All I have found is that the trike does work, nothing about others working or not. I can't find any trike pulleys on eBay right now.

Special socket? I seem to remember from the videos I watched the front is just a t70 torq. Should be relatively cheap at my local princess auto (similar to harbour freight) if I don't already have one, I don't think I do though.
Does anyone know if this will fit? The price is right!

Here is a good thread on changing the front pulley. Different bike but process is the same. Also, your speedo and mileage will be off unless you can recalibrate.

yes I know those will be off, but I've got a FP3, which has speedo correction in it, so I'll just run that right after the swap. Thanks for the help!

Should fit, that's the part number I can find everywhere, but I have e no idea how to confirm if it will, or any of the other ones for that matter.
