I've got a 240bbk with vforce and lrd adjustable exhaust stock carb. Got the needle that came with the vitos kit in the carb. Castor 927 32:1 300main 30p in the carb. Not running right no power.
bikeI compared the stock needle , the fmf needle that came in the power up kit and the blue vitos one that came with the big bore kit and I couldn't really see a difference between the stock and fmf and the fmf never gave me problems but that blue needle from vitos is really skinny like a tooth pick so that's why everyone complains of a bog when using it
Ya alot of people do. I run one with mine and love I've got a stock 250r carb I was thinking about trying. Would it help on the lower end better than the stock carb? Or more for the high end.
