Running On Two Cylinders
« on: August 02, 2018, 06:50:56 PM »
I recently rebuilt the carbs on the K1 including setting the float hights, but couldn't run the bike untill the exhaust fiasco with David Silver was sorted out. Now after fitting a new set from CMS which fitted great, i took it for a ride, ten minutes into the ride it started to misfire running on two cylinders, managed to get it back home which was not easy in hilly Wales. Touching the silencers revealed that it was only running on 1 & 2, while rebuilding the carbs i replaced the fuel pipes from carbs to petrol tap as the old pipes were crumbling at the tap ends and leaking. The new pipes i got off ebay which were 5mm bore thin walled. What i discovered was one pipe feeding cylinders 3 & 4 had kinked on the bend close to the tap stopping the flow. 
  So i can't rely on this fuel pipe from ebay. where do you guys and gals  get your fuel line from, and would you use 5mm or 6mm.
