Gas tank spacer when installing velocity stacks

[giff]

Hi everyone, I just put on velocity stacks and all went well. However, the stacks are going to hit the gas tank. I figured I'd need some kind of spacer under the front of the tank. What should I use as a spacer and how thick should it be? My lady is a 2000 standard. Any suggestions?
                                                                                           Thanks,
                                                                                             giff

I use a rubber shock bushing from my pick-up. It lifts the front of the tank about 5/8" and being rubber, provides a bit of cushion. You'll need a longer bolt.

I did the same thing with some old replacement freeze plugs that had been sitting around for a while. Raised the front and back about 1/2 inch. I also had some longer bolts sitting around.

I had the same problem on my 97 with an IS tank. The 1/2 inch spacer in the front gives the the clearance you want but the tank has then gone from a 4-point mount to a 2-point mount and has the ability to rock left to right. It doesn't take much of a rock for the tank to contact the stacks and leave a small dent. It probably isn't any good for the front and rear mounts to be carrying all of the load either. When I repainted my bike last year and fixed the tiny stack dents I was going to make sure it didn't happen again and following is my solution. If you look at the upper left and right frame rails with the tank off there are rubber mounts that wrap around the frame that the tank contacts. When you raise the front with the 1/2 inch spacer you lose that contact and hence the rocking. I glued 1/4 thick rubber strips 1" wide x 3" long to the bottom of the tank in the location shown in the following pics and there is no rocking now and my paint is safe. If you use a different thickness front spacer you will of course have to compensate with a diffferent thickness of rubber pads.

Raising the tank, has the effect of increasing the available air to the airbox, but only if you don't use a windshield or a fairing.
