I bought this jet kit after installing the cobra boulevard exhaust. All i was looking for was to stop the exhaust backfire when I let off the gas. Being in utah the stock jetting is lean and putting on the pipes makes it worse. I had Steadmans in Tooele install the kit because i wasnt too excited to drill out the mixture plug. It cost me 2 hours labor but worth every cent. No more backfire, no more using the choke on summer mornings, im getting 42 mpg, and up against my buddys roadstar 1700 he can no longer kick my butt in a drag. The 1100 out performs his 1700 not by much but enough that he cant pass or keep up. This is a pretty cheap mod that will certainly boost your performance!Read All Reviews

Put this on my 2007 crf250x used 160 main, used the 42 it was same as stock but put new one anyway The red needle on 5th from top would only fit once the main jet was changed (stock was 130). did modified air box mod, removed screen on air filter, twin air filter, removed baffle from exhaust pipe. Also boysen quick shot 3. also put quick adjust fuel screw. turned fuel screw 2 1/2 out. took better part of a hot august day to complete. It was well worth the time and money. Took bike out around yard front tire comes up easier, more bottom end power and less bog look forward to a long ride. make sure to read all of instructions as my carb was an alternate instructionRead All Reviews
