Definitely a cool factor. The ultima has one that I'm really diggin a lot. Powder coat the cover and it would look silly. I will have to post a link when I can. People bitch about the sound but I like it. More of a hot rod feel.
I would say eBay. The only problem I have with eBay is that some of the ones are not real specific on whether it fits or not. I don't wanna start putting it on then realize it does not work. EBay definitely has some of the cheapest ones.
I just bought BDL`s belt drive for my Rocker and it does fit but I have to find a 9/16" spacer for inbetween the motor and the motor plate. And then I am gonna need a 9/16" space for the crank pulley also. From what I can find knowone makes a spacer of that size. If you know of any one that does let me know. I might just have to buy a 3/4" spacer and mill it down, and make the pully space on the lathe.
BDL is the way to go. Less maintenance. No primary oil to change! I can get you a great discount on most open belt drives including PM. BDL, etc. I dislike Ultima's. Quality is not very good. If I had a few grand to part with, I'd be all over it! Everyone call the shop and tell Shawn I need a BDL belt drive for a Christmas bonus this year! PM or email for pricing with the part number please. I can save you a substantial amount on these.
defenetly give it that hod rod look like it my self but not enough to spend more than a couple hundred. you spend that kind of money I would want some power gain or something not just a look. But then agian thats what everyone wants is there own look. at leased for the area there in;.
I have run bdl and primo with no problems but went on the cheap with the ultima race unit and after 3000 miles the clutch hub/basket is notched where the clutch dogs ride think it is soft alum. so I would go with bdl.
I found a new Ultima for under a grand. I think I am going to get one and do the rims later.
Phatts make sure your getting the Rocker adapter plate as well. I was going to pull the trigger on a belt drive but the best price I could do was around 2600.00 bucks...
