  1. The story now come to an end - hopefully! I obtained a Nr.5 pipe (thanks to Leslie Brown, the Bavarian Triumph Emporium!) but before fitting it I pulled the injectors out do double check where the misfire was. This time it was Nr.6 that did not spray, and replacing that injector cured the fault. Have since covered a couple of hundred miles, including Autobahn, and things seem fine. The car drives much more smoothly with a CR MU on a CR engine! As the faulty injector had previously been in in Nr5, I can only imagine that some dirt was in the pipe which found its way into the injector t
  2. Thanks also Bruce - I did a visual and blew through the pipe both ways - will take a closer look tonight When taking the original MU off, the O Rings were intact and the bolts quite tight. Phil
  3. Thanks John I'm with you on the Sherlock Holmes deductions about the MU, and will replace the pipe as soon as I get one - even though the current one looked clean and blew through easily in both directions. The banjos are both new, and have also had their positions swapped. Will examine them more for any contamination on their next outing (am getting very fast at MU removal now!). The MU was a KMI service exchange unit, so came complete and was supplied with new O Rings for the banjoes. Phil
  4. That's right - even when you crack the pipe the flow of fuel is much less than cracking the pipe on another cylinder. Put any injector on Nr5 and there is at best a small dribble at high speed. The same injector on another pipe demonstrates a good conical spray throughout the engine RPM range.
  5. Hi everyone, I'm really looking for help and inspiration to solve a fuel related misfire now that all logical fault finding paths seem to be exhausted! Am running a 1975 CR which has been getting progressively richer during the past few years, so finally, after many attempts at tuning, the exhaust smell prompted me to exchange the metering unit. Then things got a little crazy! I chose the correct MU for the CR engine and had to modify the fuel return as this version of the MU only has the screw fitting, but the car had been built at some time in the past with a push fitting pipe conne
