Keihin fcr 33 ...any body use one?
Permalink  
 


Hi there. Just recently got myself a ttr and it rums a fcr33. I have just took it off to clean it out as it overflows if the engine is switched off and fuel is on. Does anyone else have experience of these carbs?  If so what jets do you use and have you any advice?

I wasnt at first as it kept on leaking and it wouldnt pull in the top two gears. 14_43 sprockets with a 120 rear tyre. Down geared it to 13-52 . Still with a 120/90 tyre and it revs out easily now..had it showing 140kmh on speedo (87mph). Being an OE with speedo running off sprocket I have no idea what speed I was really doing probably about 65. I was going to swap the carb but since using nearly every weekend it started to run and start better. It now pulls from zero revs really clean. I think it was set up correctly but because it hadnt been used it was just gummed up a bit...runs great now

On mine 14 and 44 max speed 118 km/h on the clock. However the GPS showed max speed only 96 km/h
