I knew that my raptor was running a bit rich so taday I rejetted it with
25 pilots
150 155 mains
and air screws at 2.5 and 3 turns out
and wow does it RIP! I am running the yoshimura titanium full race exhaust and removed snorkel and airbox lid with 6 1" holes with uni vents. I thought it ran good before being rich but that was NOTHING compared to now! had a blast today climbing hills!

 

I hope you used a new plug when you jetted It, and not reading the old rich running plug. Check it again for a few days. Theyll run like he|| right before meltdown so be careful. And If you got it dead on then congratulations!

 

I cleaned up the old plug with a bit of sandpaper to get a good reading

 

how does the oil filter cover look ???and where did you get it . been waiting for someone to make one

 

I jetted my raptor with 150 155 mains and didn't do any thing to the 'screws' and removed the snorkel. It ran awesome ,big time difference-climbing some long steep hills in 3rd --no problem!!! I wanna check the plug again just to make sure how it's running cause it was running like a raving lunatic he he. I ordered larger jets(160,165,170) cause I wanna remove the air box lid. Can't wait....

 

Terry, I cant wait to try it again and see how it compaires to my TC silencer and jetting. What do you think about the two down low, how do they compair?

 

down low is where it made a huge difference, it pulls HARD! I was climbing and making my own hills over black hills (the first place we went) I'll let ya take it for a ride and see what you think. I can't wait for this saturday, hope it's warm!

 

me too(temparature)!!!

 

I am still a little too lean myself. Went riding yesterday it was 40 degrees outside. I have big gun headpipe with wbros slip on and wbros air filter. My air box has 4 one inch vents and the baffle removed. I have 27.5 pilots with 160/165 mains. The bike runs good but after checking the plug it was still like new (no carbon) so looks like I will have to step up to 165/170 on the mains. Anyone have any feed back?

thanks alot,
mike
