I just put on the GYTR pipe on my girlfreinds 450. We just rode up and down the block, and we both like the better bottom to mid range power. I also got 23" paddles on and will try them out at Glamis over New Years. I also git her the EPI clutch kit...it'll get installed next week. Will do a ride report later.

 

Very interesting. I found lots of interesting info in that article. I have always broken my vehicles in a little hard and had good results.

 

Very interested in your results from the clutch kit.

 

thanks nice reply's, i'm still waiting for my yamaha exhaust to come in and jet kit, got my k&n air filter installed, as far as break in, i've owned 10 atv and never once have i ridden them any different, fire them up and hammer it, never had a problem, same with my snowmobiles and motorcycles, has anyone put in the iridium plug, i did and it seemed to start quicker and a little snappier, the epi clutch should give it some real good low end snap, but i think the only way to get more top end is going to be the cdi card and gearing changes, i would love to see 60 in the flat's, but i'm more than happy with the performance in the trails

 

What is a CDI card upgrade? Ignition?

 

The cdi should be released this spring, Im picking up my clutch kit today and going to install it this week hopefully.

 

I was also going to recomend everyone to read this link. It does have a lot of good info.

 

cdi card should be great when available, also has anyone installed the epi clutch kit yet? if so any results? is it hard to put in? any trick's for the install?

 

Help a guy out here fellas.. What does the CDI upgrade include or do?

 

CDI card is suppose to increase the rev limiter and adjust the timing so it let's more h.p. out of the engine, the stock cdi card under your seat limits these adjustments
