Skunk Posted August 15, 2015 Share Posted August 15, 2015 No reason for posting this. Just thought some of you might be interested. It's a Pre89 F3 class bike I built from bits I had. An 89 ZXR250 frame with a 78ish RD400 engine. All parts are Pre 89 except the electronic ignition and the tyres. Engine has been modified from a 180° firing interval to a 270° interval - because I could. Std (rejetted) carbs, HVC chambers, Ignitech programmable ignition. Not competitive (especially with me on it) but great fun to ride, and a beautiful sound. Slowly developing the bike to be better and faster. Yamaha claimed 45hp (same as Kawasaki for the ZXR250) and this currently has 48hp at the rear wheel without any engine mods. 6 Quote Link to comment Share on other sites More sharing options...
