Iso upgrades

I'm thinking about upgrading my bike to vernier isos. Mick Hemmings makes a kit for the isos that doesn't require replacing all the guts. I'm also really interested in that new Taylor headsteady that Clubman Racing is selling.

Comments/opinions? Am particularly interested in hearing from anyone who's using either of these.

So how does this sound for iso clearances: .010" rear, .035" front?? :shock:
Earlier this year when I replaced the worn-out swingarm spindle it tightened the handling up considerably but the bike still felt like it had a hinge in the middle. I think I know why now.

I'm going to be pulling the front mount and having a good look at all the pieces. I guess if I want to go ahead with those verniers now's the time.

BTW that rear gaiter was really a bear to peel back. I ended up removing the oil tank (had to anyway to trace an oil leak) and then cuttting part way thru the gaiter. I thought I could wrap it with some electrical tape to hold it together. I know it's a hack but what can you do. Was wondering how do you experts deal with that thing?

As for the headsteady, would upgrading to the 850 box-section unit make any noticeable improvement? Or should I just save up for an iso unit?


I have made a rod end headstedy for the chopper that I am building and also one for the frount mount.just think NO MORE SHIMMING! I am thinking about making a few for sale as a bolt on kit. me and dave talked about the rod end setup before but I think it will last ok as there are a lot of harleys and buels out there with rod end setups on them. if you would like pics I can email them to you but they are a little diffrent than for a stock bike.

Debby / Dynodave,

I seem to have the opposite problem with my Iso boots. Instead of the rubber becoming hard and stiff, it perishes and virtually crumbles apart when you attempt to peel it back for inpsection. Any thoughts on this?

I too am concerned about the Taylor head-steady for use on Commandos. My Electraglide has a tie-rod style head-steady and it's performed well for 37,000 miles. However, the the Harley frame and engine mounting system are designed around this tie-rod set up.

The rubber Norton head-steady may absorb more vibration than the tie-rod style? Will the tie-rod head-steady cause fatigue damage to the frame over time?
