Ok, back from a stint in the shed (as you do) I set up the steering stem sitting on my Trace Elliot bass speaker box....(those Bass players amongst you will know what this is).....Just the right height....removed the box supporting the engine, and with my weight over the standard footrest throughbolt.......the rear coilover compressed about 1/2 an inch. This is with no preload on the spring. The coilover has about 80 mm of travel, and as I said earlier, it has a 250 lb. spring. It all looks ok so far.....Something you may not have noticed in the photos, is the rear mount I made to hold the coilover. This is braced so it will not flex.....this is something I have heard some complain about with the new coilover that Laney Thornton supplies, mind you this is with two up riding and extra baggage. It will also happen at the front, where it will bend the throughbolt and the two bosses at the attachment point of the UFM. This too I have braced, as per how Davidd had done on his Grey Flash racer. These mods are necessary, as the original mount points front and rear, were only designed to take the loads of the shock absorber only.....not the shear tension/compression loads of the springs.
