Just wondering if those with experience on the twins have had any issues with the front carby suffering from fuel vaporization after a run and engine up to temperature. Just fine tuning this new twin of Rodney's and it runs quite badly if you start it after the engine has been run and sat for say 15 Minuit's where it heat soaks the front carb quite a lot, and on re-start it struggles to run on the front cylinder until you ride it and the temp comes down again. I have the mixtures set quite rich and the float level is correct.......It is running new 289 carb's. Cheers.............Greg.
