Ironhead belt primary drive??
Hey all,
When I was building my chop in '07, I tried to get set up with a belt primary, and was told by Karata- "six months"... Of course, I ran out of money and am still using the original setup. So, is anybody using belt drives, and how much better or worse are they, who is making them, yapp, yapp yapp. Back 15 years or so, I saw primo was making them. Thanks for any info.

Belt drive
PipeDreamz carries a 3' belt drive for Sportsters as well as other sporty products. It's pricey, but cool as hell looking.

Good luck finding a complete belt set-up for iron heads! They are problematic for this app. I would spend the $ on a clutch up-grade and rebuilding the chain pieces. I'm pretty sure the best you can get is replacement belts for existing units anyway.

My '64 had a belt drive in it until the belt blew and mangled the primary case flange. I'd spend your cash on something else.

Believe me I did! I was afraid that that's what would happen. Those primary chains are virtually indestructible. Iwas just wondering if things like this really happened.

A reasonable solution to a non-existant problem
Spend your dollars on barrels and stroker kits.

A fellow Bastard on the QCB board did a cool little belt-drive...
...setup in an open primary on his '73 a few years back.
He sealed up the trap door, fabbed up a filler tube for the tranny, and ran a dry clutch in it.
Since he was already into it, the next logical step was to do it up as a jockey shifter.
He put in a lot of garage time doing some fantastic fab work on it, and the results bore it all out.
It's still being run (HARD!) today with no problems, so you never know.

Open primary?
Hey all,
did he leave pics on the QCB board? I'd like to see how it all turned out, etc.
Got a link, or point me in the right direction???
Thanks

I had a Karata 1'5" primary belt on my '74, great conversion no problems with it. The new owner is stoked with it as well. With the 'hot cams' porting and polishing, big valves, belt-drive and a Super 'E' it was awsome. The delivery of power was so smooth. Even though I swaped it for a '68 I know that I'm gona miss that side of it. Oh well!! back to wrenching!!
