I just Checked my plugs again and the mag side plug just didn't seem to be like it should. It has no color change to it, slightly black/white/brown. But no where's near like the other plugs are (all brown with a little black) So I checked that plug for spark and it wasn't, so I put a good brown one in that plug boot and it sparked like it should. So I threw that bad plug out (which was brand new btw) and put another new one in. That plug that wasn't firing might have been one that I fouled and got put in by a mistake.

Now all 3 cylinders are firing like they should, So I was wondering if this will fix my low RPM problem? The sled gets to 120-130 KM/H and hits a wall and won't go any faster. I would take it out on the "walking" trail behind my house, but a cop just moved in 2 houses down!!! :cussing: :!:

Yes. One bad plug will basically cause about a 40% power loss in your situation.

Well I have some good news!!!!!!!

I was siting home just itchin to get out and see if that was the problem. So I saw that the cop down the road wasn't home (4 runner was gone) and The sled was already warm (had a fire on all day in the garage) so I fired it up and took it down the old rail bed.

Man does it fly!!!!!!!!! revs a little over 8K and pulls like there is no tomorrow! Must have been a bad plug right from the factory, because it was new. Now I can't wait to get out on the lake (or straight aways for that matter) it pulls real hard mid-range, like it should! Now that polaris in the garage won't have a chance!

Ya, now I'll have to learn how to ride again! Like going from a 380 fan to an 800!

I only rode it twice, so it's not like I mastered the hole thing anyways................

Plugs are all running brown, center one is more of a yellowy brown, but by the looks of the pics on the net of what a good spark plug should be running like I'm more than safe.

All this time screwing with the clutches, and it was just a simple damn plug!!!
