Just want opinions from people who have done the carb mods by Dave and Briain (shim needle, drill slide, and re jet) on their 650L's. How MUCH better is it now? How MUCH was your gas mileage affected? Is the LONGEVITY and RELIABILITY of the bike affected? Was running temperature affected? Is there much difference in power? Overall, was it worth it? Just interesed to see what people think. Also does anyone know where to find Honda OEM parts online.
