Handlebar Riser's
In building my basket case I had no risers to refurbish. I bought a set from VTWIN and installed them. If I tighten them up you basically have no rubber movement in the bars? Is this normal? In the bottom of the Vtwin risers it appears the rubber washers are there so there is rubber all the way to the bottom of it.
Is there suppose to be any noticeable movement in the bars when tight?

Re: Handlebar Riser's
I had this issue too when I bought my 48 from a guy. It was converted to a wide glide front end with Timken bearings. I hated the risers. I bought a set of billet 8" aluminum risers that were solid metal on the bottom, no rubber visible. I bought 4 ea. 1.5" rubber washers from ace hardware in town. That dampened them quite a bit.
What type of front end do you have, springer, wide glide ( as some are that way now ), hydra glide? Take pictures. There are ways to address vibration at the bars.

Early rubber risers have a small amount of play/wiggle when installed. Look at a parts book to compare what you have.

Re: Handlebar Riser's
There are two rubber/steel composite cup washers on each riser. The top one is captive within the riser when the bushing is installed, the other goes on the bottom. When bolted down with the correct parts the steel riser body has a gap of approximately 1/16" between it and the top tree. This allows the bushing to control the vibration. As stated there is a slight amount of movement when installed properly (it can vary based on the bushing material, original equipment seems to be stiffer than aftermarket).

Re: Handlebar Riser's
I will just shim it a little at the bottom on the inside to let it bottom out. That should give it a little movement. The outside of the riser was just bottoming against the top stainless cover. Just wasn't sure if it was suppose to have any. Thanks

I don't know what the V-Twin riser looks like, but here's an OEM rubber-mount riser with correct bolt and castellated nut:

Re: Handlebar Riser's
Are these made for the bolt threads to bottom out or just tighten to your satisfaction since it has a lock nut?

Re: Handlebar Riser's
The nut is tightened normally, as tight as you can get it; it's a lock nut because you want it to stay tight! When fully tightened, the riser body is about 1/16" above the top clamp cover, as previously said. There is a very minimal amount of shake in the handlebar, just enough to dampen that road buzz.Tudelum48 wrote:Are these made for the bolt threads to bottom out or just tighten to your satisfaction since it has a lock nut?
I made a tool for the head of the bolt because I don't own any screwdrivers that huge. I put a short 90-degree bend in a piece of 1/8" x 3/4" flat stock about a foot long. Works like a charm.

Re: Handlebar Riser's
Yea they have some play, that's why they are rubber.
But all that has been well answered already.
