Fouling plugs need help

[Rick Chalut]

Hello
I have just purchased an 08 nytro rtx . It has a pcv, exhaust, and k&n intake. Took it down the rode and it fouled a plug. Changed the plug and it ran great again but after 2 minutes it fouled another one. I use to have a dragon that would foul plugs if I touched the throttle be for it was hot. So I did let it warm up. Any ideas?
Thanks guys

With the nytro you shouldn't touch the throttle till the red light goes off on the dash. What plugs are you running? I didn't have much luck with cr10ek and fouled them easy. Put my original plugs back in and didn't have an issue since.

I am running the stock plugs. The the ngk cr9e. Should I get a set of the eya? They were better in the 2 strokes for plug fouling.

Put it on a track stand and run it good, get here good and hot if it fouls a plug you will need to look at the pcv. Thinking it was not up to temp.

I am pretty sure it was up to temp. I will try another set of plugs tomorrow. I have the trail tank on it so it is a pain to change them. I am leaning towards the pcv also. Not sure what I can do with that though.

Does anyone have a new map for the pcv?

Who's map did you get.
I got mine from Ulmer and it has been flawless.

I just got the sled. The receipt for the pcv was from Ulmer.

I told Allen what I had done and he sent out the PCV programmed and it's worked, as I said flawlessly.
If you suspect the program or programer just unplug it and return to stock, (just don't run it to hard you may be a little to lean)
If it is the PCV contact Ulmer racing he seems to better than most about standing behind his products.
