Got the big 3/Uni.

Header was glowing all the way up near the heat shield. Here is a pic of the plug. It was from casual trail riding 2-3 gear mainly. About an hour.

Front side


Back side


Yes that is the same plug. One side was WAY darker than the other.

Is that the OEM plug or that fancy racing plug?

Yeah its running rich. Most dobeck programmers are set to run a little rich to be on the safe side.

Are you noticing it stumbling and loading up? Careful where you remove fuel when you don't know where you are rich or lean.

TBH it felt amazing riding it.

Granted I havent road it since last summer then installed everything.

But the power throughout the entire throttle range felt way better, just loud as hell, and those plugs seem to improve responce a ton.

Im thinkin Ill buy 3 more plugs this week and go do the old 1/4 throttle, 1/2 throttle, and full throttle thing and compare them.

I *think* it just mainly runs a little hotter but greatly increases throttle response.

Don't quote me on it though :)

If it runs hotter does it impose any increase danger to the piston, or other internal engine components?

I’ve been running that plug longer than any of the other guys with no issues.

Thats how mine looked and I am running stock. I guess there is nothing I could do about it though.

What makes you think it's runnung hot ?
Yea I was just told the plug was a higher heat range. Not sure if it is or not, just wondering if so could it cause damage to piston and or anything else inside the motor.
