I'm thinking of putting a clutch kit into my 450 kodiak/Grizzly and the dealers here swear by the Highlifter units. They claim it will provide realistic gains of 4% torque and up to 25% horsepower. They claim only a slight loss to the top end.

They are however in my opinion pricey and are they as good as they say.[img]i/expressions/face-icon-small-confused.gif[/img]

 

Wow- I'd gladly give up a little top end for gains like that in those departments. BTW- nice garage there, head...................

That's what the service manager says to expect and she (yes girls I said "she") has been at this for a long time. The highlifter website is far more generous with their numbers.

P.S. If your refering to my avatar, that's not my garage, (although I wish), but rather one part of my local dealer's showroom. Right now that part of the showroom is full of sexy Yami 4 stroke sleds, but I will have to make do with my MXZ600 for this winter. Besides, it was worked over by a buddy of mine, (carbs, hi-perf reeds, etc.) and is probably pushing 120HP. [img]i/expressions/face-icon-small-happy.gif[/img]

 

I love the EPI clutch kit, I dont have any experience with the highlifter kit though.
On my wolvy I gained probably 5-10% torque, and 15% hp(but remember you are not actually adding any power, you are just changing where and when the engine makes the power. I lost about 4-5 mph on top end, but got it back with the addition of a pipe, jet kit and filter.

 

I fully expect to lose top end but for a utility quad my 450 is plenty fast (56 MPH with all the add-ons I have). So if it will only do 50 MPH after the clutch kit that's OK. I will then look at a pipe, jetting and air.

I'm after torque and snappy acceleration at the start and low-midrange. If these kits will do this then I'm ready for one.

 

Yes the clutch kit will give you a snappier acceleration up till top end, and more torque down low. Check into the EPI clutch kit as well as the Highlifter.

 

Do you think it'll turn it into a wheelie popper? 'Cause I think thats what I'm lookin' for.

 

you will be able to pop wheelies with it, by pulling back on the bars, but no it wont turn it into a slam the gas wheelier The 450 just doesnt make enough power for that.

 

If I do the clutch kit and don't really care about top speed 'cause I don't ride all that fast anyway, I wouldn't need to any type of intake or exhaust mods, eh? I mean just the clutch kit is okay to do by itself right?

 

yes the clutch kit is ok by itself you do not have to do any other mods with it.

They would just help add a little more power if you feel like you need it.
