what does your plug look like?

 

And? What else was done?

 

didi you break it in properly? and make sure the cams are timed properly not 180 off?

v581

 

I put in the shop and had a mechnic put them in and I broke them in like he told me to.

 

you know what , i had a service department do mine and they F^cked up. After i got it back it was slower than when i brought it there. After going threw many of jettings and no improvements i brought my quad in and had them remove them for me. They took them out it for free what does that tell ya. 8months later i find a new guy to do my work and had him put them in and then they were done right. i felt the power increase on mid to top but felt the loss on low end. Thats with both cams.

 

Thanks for your answers. I think thay just have installed them wrong.
