Clutching Question

[nhrxrider]

O.K., I have to say it at the start, I know zip about clutching. I have the general physics of it, I have a basic understanding of how it works, but I wouldn't even begin attempting experimenting with changing weights, etc. With that said, I see many people on here comparing clutching. Its my understanding that there are a LOT of factors which affect clutching...overall weight (sled + rider), temperature (and how it affects the engine, indirectly affecting the clutching), altitude, gearing, snow conditions, etc., etc., etc. So how can people compare clutching? I would think unless the same person was going to ride another identical sled on the same trails, then the ideal clutching would be different.

O.K., with that said, is there any clutch kit on the market that would help me for general performance trail riding, but is something that I can set up myself? Kind of a generic bolt-in and go, that would be better than the factory setup? Sorry to ask such an ignorant, newbie question, but there it is. I know where my knowledge is, and it ain't clutching!

Actually it is a very common question here, and a good one. The turbo will give you more than anyother sled will handle, and you will rule your area that you ride. Of course unless you meet another RX with a turbo as well.

But as far as a bolt on up grade that will give you a very noticeable difference, that's easy a "ECP FILTER KIT" or "RX POWER UP KIT". This is a kit consisting of filters, pre filters, crankcase filter[vent], carb springs, jets, multi angle secondary helix, springs for both P & S and clutch weights. There are lots of riders here that have used this kit and rave on it's power and acceleration, which is perfect for trail riding & ditch banging.

Very easy to install with easy to follow instructions, and the two gentlemen that sell the kits are on here regularly. Both are very helpful with any questions you might have with the set up or installation of that kit.

You have come to the right web site if your an RX owner!

In terms of clutching kits, adjustability is the key. Take the clutch kit I have. I bought it from Matt. Change of helix, secondary spring, primary rollers, and a set of heavy-hitter weights. I set the thing up to perform beautifully with a 121x1.25 and 144 nails. Blew that track up, switched to 144x1.25 and 0 nails - when I did and without touching the clutching, the engine speed decided to jump up to 11k (from 10400) - just play with the weights (and with a lot of PM's to Matt), got that pulled back down and it again works really well.

nhrx rider, From Aaen you can get the clutching handbook, which is probably the best thing out there to understand clutching.

On the RX1 and the new vectors, you have a wide torque curve which makes clutching pretty forgiving.

Some people screw with the clutching when they dont need to. If you are out on a lake and hammer your throttle and it goes to the power peak and stays there, that is really all you need, that and a good backshift.

And you are right in that your weight, the temperature and what not all play a part.

Sorry Had to go and never finished what I was saying. I hear you when you say something to just bolt on and go, but clutching alone is only phase one of a few things you can do. I truely believe you would be disappointed if you only did the clutching, as performance gains really are a true blend of motor, carbs, clutching, exhaust and traction. Now maybe you're not prepared to go that far or spend that much, I still think the biggest bang for your buck will be the ECP Filter Kit. Although a good roller secondary does shift smoother than stock and is a direct bolt on now by Bender.

Sounds like you do most of your riding on groomed trails, so quick up shifts and backshifts on your clutching is what will serve you best for that riding style.
