This post is to see who else on this forum has made engineering changes to there bikes to get there steed to the latest and greatest GP fashion at the time, or performance mods of dubious nature Me for one having all the engineering equipment at home ie lathe, mill, drill, polishing equip, and gas welding etc have been guilty of the following, Mechanical Anti dive ie links and bars attached to standard forks (Kork Ballingtons KR 350 I think from the early eighties) great in the dry, you could emergency brake with the handle bars rising 1” but auto lock up in the wet. (SR500) Leading link forks as per the trad Guzzi 350 single from the 50’s fitted to a XS650 Yamaha with modded frame single seat, home made reverse cone mega exhausts, wire wheels twin discs etc. Looked the part. Rebuilt my Laverda Jota from the ground up including full engine overhaul, had to strip it to the cases 6 months latter to get at the spring about the size of a cigatette butt that had broken leading to a semi auto gear change when you least expected it Custom triple clamps to mod 600 Yamaha seca for mate to include GSXR1100 forks and brakes and re-machine Suzuki across front wheel to take twin discs and custom axle bolt etc etc Too many dollars on cams valves pistons from every part of the world reduced to scrap metal in the pursuit of speed and or Horsepower Current project is a 750 sfc laverda (SF2 74) replica mods included are GSXR 750 twin spot callipers on custom rotors/carriers, extensive frame mods including lay down twin shocks and full mod to sfc stand etc ground up restoration on basket case bike might include 76 deg crank conversion and just thinking about fuel injection. Currently building my tube bender (mandrel type to make my headers) so making the tools to make the frame etc on the next project, so the story goes on and on and on Whats yours………..???
