I think I'm finally getting there on my jetting. I need someone to post a pic of my plug chop. I can email or text. I want to get your opinions before this weekends ride. Thanks.

These are pwk 35 air strykers at 2400 ft ...I'm running 40 pilots, needle in middle clip ( cel), and 138 mains. Mods in my signature. This was a 4th gear run due to limited space. My plugs have a golden brown color after about 45 minutes of riding that i pulled out of it. Looks like I may need to step up a jet size possiblely. Let me know what you think. Thanks.

Help me out.....I don't want to melt it down this weekend.

looks to me like you need more room ... rev it out 1-6.. maybe even do 2 passes ... looks like a weird reading... by the way im running f.a.s.t stock cylinder/stroke aggressive dune port. I have the same carbs and im running a 155 main.. im a tad rich but im on the safe side.. but im around 900.el

I guess I can run it down the 4 lane....Damn this will be interesting. Changing plugs on the side of the road.....traffic .....oh well I have no choice. I thought it looked a size or two small. Overall the plug looks great though with some ride time....nice tan color.

how does it run? i dont really have anywhere to ride my bike around my house.. i have a small blacktop road down the road from the house... I warm up my bike on old plugs , pop in new ones and fire up the bike. i do 2 passes wot 1-6 .. on the last pass i hold it pretty tight in 6th let it really rev out , then kill it and pull in the clutch.. should get a good reading by doing this. just make sure you rev it out tight in 6th. post back results

Bike runs strong. I think I will step up a couple of jet sizes to like a 142 from my 138 in it now. I swear it seams I'm using some small jets compared to what most people end up with. Although I realize air stryker carbs usually end up using smaller jet compared to standard pwk's. But everyone else ends up with 155's or so with the pwk's ....just seems like a drastic difference to me. Scares me that I will destroy my top end. When I start using bigger jets my plug gets really dark when i put some ride time on it....but I did drop down 2 sizes on my pilot if that would affect overall plug color?

Just went out and did a chop with 145's. Wow I learned a lesson....make sure you get a good 6th gear pull! My 138 chop was only through 4th and looked slightly lean. Todays 145 chop looked even leaner ....looks like i will be up around 150-152....just like Kevin @ HJR had said I should start at. He suggested 155's when i put it together. Although my pilot jet is pretty close at a 40....may end up at a 42 though.

yeah im running 155 mains good to see you got it figured out.

[RadarRacing]

Unless you have really rich needles it should be in the 148-155 range. BKM we have places to jet down here if ya need room. About 25 miles from kcmo.

Yeah I'm headed to grain valley this Friday for the sand drags might test my little ported 350 there
