Bruce I kind of recon you might be right........Though the Horner's did build their bike very quickly with little time for any mistakes in it's build. A couple of interesting points that some might not be aware of. The reason they chose to use two coilovers on the rear is that for the shock absorbing they have one set up for bump and the other for rebound. The other very interesting thing I learnt from Barry Horner at Eastern Creak when we were racing there last year, is under the seat area they have a small pump that looks like a modern day fuel injection pump, but it is actually a vacuum pump used to scavenge the engine. Anyone who knows much about serious racing knows that creating a vacuum under the pistons helps to create power, as well as reducing engine oil leaks to near nil. This would all be knowledge they have gained through their work with Touring car racing here in Aussie and other race engines the build and test. They are very clever blokes, and I only wished that I'd had their help when I was building the racer.......Though it is help I could never have afforded.
