I just put 26" Kenda Executioner tires on my 04' Sportsman 700 EFI. I already have a K&N filter, and a White Bros Exhaust on it. What can I do to the drive train (clutch) to get better low end and regain some of the top end I have lost?
Let me know....

 

A Heel clicker clutch will do the trick.

 

Where can I get a Heelclicker clutch at?

 

You can go to www.heelclicker.com or you can get the cob discount here.

 

How hard is to install this? I am mechanical inclined, just never dug into the clutches before?

 

The instructions are on the Heelclicker website. Take a look at the tech support section and look at the clutch mod and the spider shim install too. The job is a lot easier with clutch removal tools. HPD has the tools on their website. Victor Specialty is another good source for Polaris tools. You'll probably need to get the dealer to install the shim in the primary which is required for the 700. I went ahead and bought the spider tool and holding fixture and did it myself.

 

This sounds great...however does the Heelclicker have any possible negative effects? Premature wear of any sort?

Just curious...

 

Not really. It will come with new primary springs that have higher engagement than the stock clutch. However, it's not necessary that you stick with the heelclicker primary springs. There's no shortage of manufacturers of these springs and you can keep the stock Polaris spring if that suits you. Polaris has a big selection of primary springs as well. You may like the higher engagement with your taller tires. Higher engagement is more rpm is need to get going, almost like a higher stall speed in a converter for an automatic transmission.

 

Ahh, thanks for the translation...was having trouble with the higher engagement thing...(talk cars and I can follow pretty good![img]i/expressions/face-icon-small-smile.gif[/img] ).

So having a higher engagement just basically sounds like you're revving the engine higher and in a sense, dumping the clutch? If that is the case, then this sounds like it IS putting more strain on your drivetrain. I know I'm probably saying this in a more extreme way than it is, but any time you raise your engagement level (thinking of a manual tranny) to a higher RPM there's more power there to stress your drivetrain components. Hence, one who "rides the clutch" tends to wear a clutch out faster versus someone that is better at RPM matching.

Am I getting this?

 

The PVT shifts by over coming a spring with centrifical force. Different weights and springs are used to accomplish this. Therefore force regardless is applied semi slowly. It does not put any more strain on the drive train. It is not like dropping the clutch. It does put more theoretical wear on the motor, but that can be argued. By having your motor turn more rpms it will turn more revolutions in it's lifetime than a stock bike, but having it perform it's tasks in the part of the torque curve that provides adequate power for the work to be performed can be better for the overall life of the machine. Now truethfully most clutch kits for the ute type bike are not going to change the shift rate so mutch as to harm the bike over it's normal life.
