Roadknee Posted April 9, 2010 JD Jet Kit 160 main 25 pilot Blue needle, 4th clip from top 2.75 turns out on the fuel screw Bought my 2007 about a month ago. Found the above recommendations using the search function. Improvement in power and smoothness is amazing. Share this post Link to post Share on other sites
dbwarfare2000 Posted November 18, 2010 JD Jet Kit 160 main 25 pilot Blue needle, 4th clip from top 2.75 turns out on the fuel screw Bought my 2007 about a month ago. Found the above recommendations using the search function. Improvement in power and smoothness is amazing. I'm about to go with the same setup. fmf powerbomb header and q4. I've searched here and see people recommending a 155 main and some 160. i think eddie sugessts 155 main. anyone else want to chime in on this? how does it run with the 160 Roadknee?

YNOTRIDE Posted November 18, 2010 I asked this same question with the same set up a few days ago and never got a reply. I too noticed some say 155 and some 160. I did JD Jet Kit FMF Powerbomb and Q4 3X3 and Uni Filter 155 main stock 22.5 pilot with kientech screw Blue needle, 4th clip from top 2.75 turns out on the fuel screw Smog stuff fell off I've only been able to put a few miles on it so far but all seems like it is running perfect. I didnt have to adjust anything after I re-installed the carb. 😛 Share this post Link to post Share on other sites

Roadknee Posted November 19, 2010 I put about 1,000 miles on mine this summer and into the fall. Runs flawless in cold and hot weather. I would guess there is not a lot of difference between the 155 and 160 main. The bid improvement comes from the larger pilot jet and JD needle. Share this post Link to post Share on other sites
dbwarfare2000 Posted November 19, 2010 i have done the 3x3 already and have a jd kit in there already with a 155 already. so i'll see how it does when i get the exhaust. if its running flawless with a 160 i think that would be the way to go. Share this post Link to post Share on other sites

I do have some decel pop but thats no big deal I kind of like it. My FJR1300 with the two bros pipes pops alot more than this one. Share this post Link to post Share on other sites
