Default Re: Livefastmotors clamshell sprocket adapter

I've had one on mine for about 1000 miles now. Make sure when installing, the sprocket is centered and in line to your engine sprocket. You can use your original rubber mounts if you need more space, or you'll have to machine the adapter if you need less. Next you'll also want to purchase bigger washers as the bolt heads are just barely big enough to keep the sprocket in place. You'll have to re tighten the bolts that hold the sprocket as they come loose often. Jim only has two sizes of the clam shell. Larger hubs will need to be machined. Someone asked if it can be placed in the front and yes, it can. You'll need spacers though. I've also ordered a thiner drive sprocket so I can run a reg. bike chain to run to the rear sprocket. I do not suggest this though if you weigh more than 160Lbs. Jim from Live fast Motors is great to work with. Below is the pic of my bike and the Clam Shell Adapter. All the bikes I build have this set up. It's well balanced and easy to install. Plus, Jim offers great customer service.


There is no moment like the now moment.
