[QUOTE="tjcassar, post: 23015, member: 1916"] I am sure not to be the first to fit a set of 928 consentrics on a Rapide. Well I have just fitted a pair and am not getting the performance expected. What is worse is that at high speed, 80MPH plus on forth gear, the engine stops pulling and starts misfiring. Once I remove the plugs for inspection, I find the front one sooty whilst the rear one is perfect. Settings are as follows: Main jet 260, pilot 30, needle jet 106, Valve 3. for both Carbs. Would one be correct in trying a smaller main jet for the front cylinder only?? Or would it be wrong to have different settings. By the way the needle is right down so can not set it leaner for both carbs. Any help suggestions appreciated. Tony [/QUOTE]
