Need some advice on my plug chop

[wfobasheeboy]

Hi all

I would like to see what you guys think of my plug chop. I started at 330 main & went to 340. I think I am good at 340 may be a tad rich.

My mods are

FMF Gnarly pipes with powercore 2 silencers

K&N 6"pods

carbon reed on stock cages

+4 timing

stock Carbs

Pilots 27.5

mains now 340

needle 3th spot from the top

 

elevation 200ft above sea L

temp 65 to 75

 

first pix is 330 main one run too 5th gear

 

 

This pix is 330 mains longer 5th gear run.

 

 

this one is 340 mains long run in 5th gear.

What ever which one reads about a 2mm ring.

340 is at 2mm

um...those are different heat range plugs........you need to be running the same 8's for all chops, or it will throw your readings off.

What do you gain from a plug chop? What set up would you recommend it for?

Yes on the 330mains run I had one set of 8s left in a box marked 9s.

 

The shee seems to run better on 9s then 8s.

[AKheathen]

when you are jetted right, and not over-oiling, or running really contaminated fuel, the 8's should run perfect. when you need 9's, like for alky, then plug chops are said not to be readable, because of the fuel, so................go back to the 8's, get the mains verified with the chop, and tune the needles and pilots to run good. if you cannot do that and still believe you need the 9's, or you throw them in and the 9's seem to work better, then get some denso iridiums, and they will run better, and be in the proper heat range. i believe iw24's? they will have the reference to the ngk "8" series on the site. either 27, or 24 is the 8&9 range.

Ok I will runs the 8s & do a 330 & 340 run & plug chop them. I will post up the plugs.

 

As for premix . I am running the AMSOIL dominator synthetic oil @ 50.1 with 92 gas.

[Snopczynski]

Are you running any race gas in this bike?

No just 91 pump gas in it.

Well carry on then. I dont ever do plug chops, I just jet by plug color and feel. Some of these guys do it though and should be able to tell you accurately how they did it.

same here. Just do it by feel.

[AKheathen]

i've done it once, lol... you usually only do it when you can't seem to get it, like when learning how it should run

This is my first banshee. The rest where 4 strokes. I pick this shee up & it needed some TLC. shee runs good now. I just would like to make sure this thing runs strong & safe no melt down. The bike was very lean when I got it "no power & white plug". clean the carbs & jetted up for the mods that are on it. I check the plugs color looked good for what I think a 2 stroke should look like. Starts good & runs good now. I was reading on here about a plug chop. So I did one to double check the mains.
