I know my local polaris dealer mechanic, who has been at this for 20 years or so, installs many snowmobile clutches and most are epi. When I talked to him about clutching my sportsmans, he highly recommended dalton....he said in his opinion they are the best, but also more expensive. Unfortunately, I have nothing to compare to as I have only used dalton. Maybe some others can chime in who have had experience with the different ones?

 

thanks guys i have decided to go with the dalton kit i will let you know what i think next week when i get it

i dont think you'll be a bit sorry and cant go wrong. imo.

 

After reading this I'm not sure if I should spend the money on a clutch kit?

"Our initial testing showed the EFI 700 to work quite well in stock form. It did, however, have some room for improvement in a couple of areas for this application (0 - 2000ft' elevation, stock tires) as the factory has calibrated it to work well for a wide variety of uses. We designed a new primary spring and a custom ground set of billet flyweights for this application. By carefully controlling the RPM throughout the shift pattern with proper distribution of mass on the flyweights and the new primary spring, we achieved better belt grip in high range, less hitting of the rev limiter in loose conditions and more consistent RPM control with no loss of top speed. This kit engages right off idle just like the stock clutching and although drag racing results only show a slight advantage with this kit installed (approx. 1 bike length in 400ft), we found high range to be more effective at lower speeds"

 

Well, you took the quote out of context and I'm not sure what they are testing other than a 700....what tire size? awsume800efi has 28" tires, he surely needs a clutch kit, but you are running 26's....I wouldn't mess with it. What you read is right if they are referring to no larger than 26" tires...

 

okay, read it again, stock tires and low elevation......I think the stock tires were 25's, so again, 26's are not much larger and are likely lighter than the stock tires, so I wouldn't change the clutches. I still would if I had 27's are larger.....

 

A 2005 700 EFI came with 26" stock. I would go with 27's when I need new ones but I had just put the 26" mud lites on my 500 so I just switched them when I bought the 700. They are 2" wider in the front and 1" wider in the back...but I don't think that would require a clutch kit. I was hoping that it was going to really make a big difference in performance, but if it isn't I'm not going to spend the money.

 

no you wouldn't be, they don't do much for a 400 with 27" tires. will help rhe 500's and really work well on the twins.........stroker<div class="FTQUOTE"><begin quote>Originally posted by: onesavage

I don't think I would clutch it either if I were you. You'll know when you put on 27's.....if there is noticeable power loss, then you might consider it. I clutched both of mine. The 700 made a world of difference, but there was a very noticeable power loss when I put on the 27's and the stock tires were 25's. The 800 I only notice it engages at a slightly higher rpm, so there is a bit of a lag off idle. However, I did not change the tire size and stayed with the 26's. I put on the orange/blue spring from dalton, didn't need a kit, was only $30. Dalton told me it wouldn't make much difference, but some people say they notice it.

no they dont work really welll on the twins. imo.
if your running the 28" tires the kit will help w/ take off from the power loss from the heavier weight and more roating mass. w/ 27" tires you really only need the primary spring to help bring the r's up a little for taking off. now this is for the 800 sportsman.
