Norman thanks for the help, I also want to do a check on the axle path, as it is very easy to remove the spring from the shocker unit. I have just picked up the remaining parts from the paint shop, including the front blades, so now I can assemble the front end for more checks. To add extra support to the original upper shock mount lugs, I am making up some simple saddles that clamp to the handlebars in between the two original vertical mounts, these will then extend down and either side of the upper shock mount, whereby a longer 3/8 bolt will complete the upper fixture......hopefully with a little more strength and piece of mind. I spent some time today modifying the fuel tank ( an Indian Repo not an original) this to clear the front cylinder TT carburetor main body and the bellmouth. It came out quite well, with only a couple of leaks to weld up....I found the oxy welding worked really well, haven't done it for years, the MIG welder spoils us a bit these days. For those in the know....Would it still be necessary to use the tabs at the rear for the lower tie through bolt...? I suppose the vibrations would still be an issue for a racer, even though it's use is minor verses a road bike. The only other mod to the tank may be to remove a section to clear the steering damper, as I want to keep it up and out of the way......And not so noticeable...some may think this is a bit over the top, but that is the kind of detail that has gone into this bike from the offset.
