ride.race.live Posted March 22, 2018 Report Share Posted March 22, 2018 well for starters could be lean with pipes.... you more then likely need at the least 27.5 pilots when did this issue start ? did it just start doing it after installing pipes or did it start randomly out of no where and no changes where made Quote Link to comment Share on other sites More sharing options...
Ayesully810 Posted March 22, 2018 Report Share Posted March 22, 2018 (edited) id be more concerned with the 200 main jet. Most stock piped bikes will take a 25 pilot as long as your not riding in the winter or late fall Edited March 22, 2018 by Ayesully810 Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted March 23, 2018 Report Share Posted March 23, 2018 Check size of both jets and report back. Include type of air filter, with or without air box, and/or lid. Quote Link to comment Share on other sites More sharing options...
Toybreaker Posted March 23, 2018 Report Share Posted March 23, 2018 mix ratio can have an effect on jetting too...... 1 Quote Link to comment Share on other sites More sharing options...
Ride2fast Posted April 11, 2018 Author Report Share Posted April 11, 2018 All right to answer some of your guys questions the wheeler is all tore apart now had frame painted but when I got it it had the pipes on it but was not running right so I put it back down to the stock Jets And started running better but did that hesitation thing right before power band so all the Jets are stock with FMF pipes all the way back and I mix 32 to 1 Quote Link to comment Share on other sites More sharing options...

Ride2fast Posted April 11, 2018 Author Report Share Posted April 11, 2018 Yes they’re stacked carbs and I hope I didn’t hurt it it ran good when I parked it besides that I’m going to order a jet kit And try that once I get it back together I figured it was just the Jets I didn’t drive it a whole lot like that maybe eight hours Quote Link to comment Share on other sites More sharing options...
Ride2fast Posted April 12, 2018 Author Report Share Posted April 12, 2018 and I have the airbox lid on with holes in it air filter is some generic kind I can’t remember the name stock jets stock carbs everything on the motor is stock besides the exhaust so I’m going to get a jet kit and play around So what would be the best sizes to start with with FMF pipes all the way back Quote Link to comment Share on other sites More sharing options...

bansheesandrider Posted April 12, 2018 Report Share Posted April 12, 2018 15 minutes with that jetting could have hurt the engine. When I had 2 bikes with FMFs, the jetting was 280 or 290 main, 27.5 pilot, clip in the middle of the stock needle. when jetting, you should always start rich and work towards lean- start with a big number and go smaller 1 size at a time. 1 Quote Link to comment Share on other sites More sharing options...
Toybreaker Posted April 12, 2018 Report Share Posted April 12, 2018 My shee has been all over the stock cylinder, stock stroke spectrum. with basic bolt ons from sea level to about 1000 feet mixing 32:1 280 mains ran the best with the FMF pipes. it ran ok up to 310 main, but ALWAYS ran best with a 27.5 pilot. toomey needle liked 1 notch closer to the tip and the stock needle liked the center notch. Start with the 300 main and do a plug chop. start fat it doesn't hurt.... 1 Quote Link to comment Share on other sites More sharing options...
