I have the Kehin race carb on my 250X and love it other than from time to time the trottle becomes very hard to push from a resting postion, once you get it going its fine just hard at the start. if the bike is not running or if the choke is on then it is fine and very easiy to push like the stock trottle. the cable is very unrestricked so I dont think thats the problem??? any ideas??

 

maybe the cable is kinked somewhere? also I have a 300ex and i think i might get a 38mm carb. Does it improve everything or just top end.

 

no the cable is not kinked at all, and yes I love the carb it seemed to help more with low end than the top however the trottle responce was wonderful all the way across the rpm range

 

do you have a cam in thier now? All i have is a K&N air filter and supertrapp exhaust.

 

yes I have a cam but when i first purchased the carb I did not have a performance cam and the carb still helped
