ok guys seeing as how im gonna have my blaster up and running in the next week or two im looking to make sure i have it jetted right. Mods are f7 pipe, and a uni airfilter. temperature is jumping around in the 50's as of now. in the winter temp will be lower than 35 most of the time. type of riding will be tight trails with mud depending on rain.
 
thanks blasterdude27. now i just need to find out what size pilot is in it. the pilot jet is right by the main right?
 
i have the f7 also, with the uni i had in before the cfm box, it pulled very very hard with the 290 in it, but i got scared it was too lean and try'd the 320 that the toomey kit suggests, i did have to drill the 12 holes in the lid to get it to run better, but still not like it did with the 290, now yesterday evening it was really cooling off when i went too ride and it was pulling pretty hard, so my guess is the 320 is still a tad too rich, seeing how its reacting better to the cooler air, i have a 35 pilot sittin at the dealers waitin for me to pick up, i think im gonna throw it and the 290 in and see how she likes that combo, and that pilot is hard to miss, it's way down inside that tube beside the main,
