I jetted my raptor, have k an n filter an aftermarket pipe, its runs good , but it seems hard to start somtimes after it sits for a week or more, but once warmed up itll start no problem, i went with the bigger jet in the kit thought id get the most out of it , and it says using that jet take lid off which i did and have a pipe, am i running too rich , i alaways have to use the choke even when its warm out, and even then it took me a half hour a couple times and its an 05 not beat, i looked at the spark plug and it is a little dark which i believe im running rich , can just turning in the gas adjusment screw a half turn make it start easier, i did turn it out according to directions with where i live an altitude??
