Replacing spark plugs

[YamahaFreak]

Just replaced my plugs and put in Cr10Ek plugs, and the first thing i noticed when taking the old ones out is how lose they were!!

the 3 cylinder was so lose im suprised it didnt come out. Just bothered me, and thought i post it up on here and see if anyone else has had same thing

Nope mine were nice and tight. That is really weird though, surprised it didn't start missing if they were that loose.

Well i made sure the ones i put in were tight!
And thats exactly what my dad said lol

Mine were the same way. I could not believe how easy they came out.

Besides the very limited access to them, they all made a good snap at the start of taking them out which indicated to me they where in there pretty tight.

Do you guys notice any difference with the CR10EK's? I thought about putting a set in my XTX this fall but never did.

Got em in the Apex and the Nytro. Heard they add up to 3HP but have no idea if it is true or not?

 

[sorenson1610]

Its hard to tell any gains but I would like to think it pulls a bit harder all the way through. But its not a night and day difference.

I fitted them at the start of the season plus an ultra q exhaust I dont know wether there is an improvement or not. I dont think anyone could truthfully feel a +or- 1 or 2 hp. I do find under hard excelleration a slight misfire at a certain rpm if thats the right word or not. Next winter hopefully the nytro will be gone my needs and wants have changed i want a crossover sled.

I run/ran them in both sleds. I ran them in the MTX my last time out in Cooke and then switched back to 9's mid day to see if I could tell any difference. I felt the 10's were just a little better, and every little bit helps!!

Mine were very loose as well. I overheated bad a couple of times-thought that may have changed the dynamics.
