well I ride the **** out of my bike and with 120hp at the rear wheel Im sure it will snap soon. Wheelies and all. I called zippers already and they said they do not make a kit yet for the new Dynas, cant seem to find anything for this bike. So I was hoping someone on here new of a place that had the conversion for sale, no matter what the chain will always be stronger

 

what all have you done to your motor?

 

My friend did the work, it is basically a 95" kit, 11.2 commpresion, ported heads, throttle body and some other little stuff. Cant tell you what the parts n ames are sorry.

 

I would recommend doing some research on belts, unless your want to constantly be lubing and adjusting a chain. They break, too.

Good luck

fit a chain drive if you can, looks, drive, fabulous, although get good advice on the rear sprocket especially now with the 6 speed box, the pic is of my 91 fxsts with chain convertion, i also have an 07 street bob which i'm doing a rear end build on, although no chain convertion at present, 180 tyre, fender cut up to the top of the tyre, custom made side number plate, nightster turn signals with all the led's inside, will link some pic's when finished.

 

Chains breaking?Yeah, maybe cheap chains...

Spend some time at the All Harley Drags.
O-ring chains solve the problem of the final drive being the weakest link.
No lubing is needed and they last forever on the road if you keep your sprockets clean and in good condition.

As stated sprocket brakes are the whip, especially on a custom build.

For all builds over 100HP chains will help to transfer the power more efficiently.
I'm not dissing belts, they do serve an awesome role, just not with maximum power delivery.
And as mentioned chainsallow you to avoid the offset rear.

If you guys can make the trip check out some of these monsters with O-ring chains:

Having come from mostly euro and jap bikes with o-ring chains, I can tell you that this just ain't true. You can religiously clean and lube an O- ring chain and the sprockets will be toast in 25,000 miles. Never lube or clean and you'll get 15,000 out of them. If you're laying 100-plus ft/lbs or torque into it, or riding very agressively, expect 10,000 miles out of the chain/sprocket combo. Chains don't really wear out that quickly, but they do stretch. Put new sprockets on a stretched chain and you'll lunch either or both in short order.Chains rarely break, butthey few that I've seen break have taken out serious hardware when they whip or jam around the sprockets.High quality chains are $125+, sprockets another $100+ (for both). If you're running a quarter mile at a time or only do a few thousand miles a year, I guess this might not be a factor.

I'm also sceptical about supposed superior efficiency of chain over belt.

Chains are great, but they're not perfect. I wouldn't swap from belt to chain unless you're making crazy power, or racingwhere absolute strength/gear ratio selection is more important thanlongevity/ease of maintenance. Just my 2-cents.

 

I've known more than one who has had their cases busted by the backlash of chains breaking.
