Zip you can't grow smaller  bars but you can cut down longer ones,get 30"s and if you think there to wide bob 'em.

It sounds good. Be aware of the hazard it poses.

KennyG,
Did you have any tank clearance issues or control cable problems when you put the 2" risers on?

I'm thinking along those lines.

Thanks.

Be aware that the throttle cable comes out the bottom or the front depending on year.
So you may need more room if yours comes out the bottom.

Tocsik,

As Verslagen pointed out some model years will require taller risers. My S40 is a 2013 and 2" is just tall enough.

I cut my risers off with a hacksaw, which is very hard way to get precision workmanship. I made a clamp out of a piece of 2x4 and bored a hole in it to match the diameter of the riser and then cut a saw kerf across the edge of the 2x4 so I could clamp it. I then bored and tapped the riser to match the existing metric fastener.

If this is your first metal project, and you don't have a n Atlas Lathe or a Bridgeport you might want to consider buying risers.

I did make risers from socket wrenches and didn't care for them.

If you have a drill press and decide to cut your risers down I can walk you through the process.
