Yes I was wondering EXACTLY what these cam's and springs are? What do they do? How do they improve power? Someone suggested doing this to my Warrior. I was just wondering what in the world I will be doing to my bike by having these put in. Oh so far here is my list of things "to do" I am going to put a SuperTrapp pipe, Jetting, Cams+Valve springs?, ProFlow air filter, later on change over to Wiseco pistons. If anyone has ANY feedback on this list of things please let me know cause im curious as to what kind of results im looking at? Im looking for more power across the whole band. And by making these mods I dont want to lose any MPH's off the top? Thanks for your time and help everyone! =-)

Well these parts are kind of hard to explain without being able to show a cut-away picture of the engine. Here's the best I can do.

The cam is the part of the engine that turns as the piston goes up and down. It's somewhat like the handle on a cheap screw jack for a car. It's strait, then bows out, then back down to strait. You hold the strait part and crank on the bow. Get the general idea? You get more power from a bigger, better cam.

I assume the springs are valve springs. These springs are on the valves and control their movement basically. A spring upgrade is a good thing to do while modifing an engine.

Some will disagree with me, but I would do all internal work on the engine at one time or not do it at all and I'd let someone good do it so they can get everything going together. Otherwise you may end up with a "box of chocolates" engine...just never know what your going to get...out of it.

But honestly, I'd get a supertrap (what's on mine), jet it to match up (carb), and an Alba Superflow Airbox (expensive but worth 2 proven HP). Then I'd try changing gearing to 12/40 (1 less tooth on front sprocket). I have heard different results from different Warriors on the gearing change, but most find more bottom-end power and more top speed because it takes that overdrive "glide-out" away in 6th gear.

You don't always have to go "hog wild" with mods/money to get some results. Depending on what your goals are and where you ride, this may be plenty and more practical to ride.

Don't get me wrong, I like all my performance, but it comes at a premium if you know what I mean. It's nice to have the extra power but I find that I have a lot of overkill sometimes.

Good luck on finding your happy medium...I'm over mine!!!

Oh, one more thing, check out some old Warrior mod posts in here, you may find some money saving tips. (Example= I saw where someone swore by boring 10 holes in the airbox and cramming a K&N filter in it, an Airbox like mine is $200, BIG SAVINGS)

So if I was going to make all my engine mods at once should I go for Wiseco pistons too? Im having a VERY well experienced mechanic do all this stuff so it wont get screwed up. Thanks for the explaination beleive it or not I understood it so I know what the stuff is now. =-) But you say that some people when moving one tooth down on the sprocket actually get bottom end power and a little more top end!? Should I maybe consider doing this also? Thanks for the help! (all im waiting for now is the money to make my mods!)

Yes you should go for the piston too. I don't have that kind but they are very good. If you are going to go IN the motor, you may as well do it up right. This way you know it all works well together and you get the best performance out of what you put in it.

I'm not saying to go hog wild in there unless you are a speed freak and ride wide open spaces. I think the bad thing is you may find you need better handling to harness the new found power. No use in having power if you can't keep the rubber side down~!!! LOL!!!

Again, you don't have to go hog wild here either. Good shocks with reservoirs that don't fade easy with a decient spring rate are sufficient. The stock fronts are too weak for me in the corners. The tires I have are also a good choice. They hook up well in all conditions. Basically just beef up the shocks, get tires that hook up on light rims and preferrably something to give you a wider stance. A-arms and axles my not be a necesity if you are not going wild in the engine department.

Just use common sense. Don't under or over shoot your goals. These mistakes can result in having to buy twice or spending more than is necessary to begin with. Make darn sure your engine doesn't over shoot the handling and the total package doesn't end up being overkill. I have a friend who rides a '91. This poor guy does things one piece at a time. Every time he adds performance, he does the old crash and burn routine. Then it's back to the shop for repairs on his wrecked quad.

Oh, I almost forgot about the gearing. It is 13/40 stock. I run 12/40 and so does another '91 rider. The '91 is stock except this and a tire/wheel package (realter rear/bandit front) and has never had a engine rebuild. This quad has been thrashed so bad you can barely tell it's a Warrior. He out runs 3 other stock '00's with the 12/40 gearing. He stumbled on this finding just trying to get more low end. He gets out of the hole 1st, maintains the lead and gradually pulls away. He pulls more speed in 6th instead of just cruising out like before.

As I said, I run this gear but I can't really compair due to the mods. This gearing was already on when I bought it. So, I can't compair to stock gearing either. I'm not promising the same results for you though. It could vary by rider, surface, elevation and all sorts of things. I believe it's pretty cheap to try and would recommend taking the chance when looking at price v/s chance to gain. It may not work for you and sorry if it don't. If not it's still worth the try and not much money would be wasted.

Thanks for all your tips and comments! I was thinking of doing all of these mods at once.......And then after a while longer maybe going for some Works shocks? Are they very good? Im really low on $$$ right now so im gonna have to do one part of the bike at a time. Although I should start the other way around I am going prolly in this order 1. Engine+Exhaust 2. Shocks 3. Tires (going for Holeshot XCT's)
So far thanks to alot of helpful advice I AM going to try that sprocket.....I think you said 12/40? If I dont feel it works I'll just change back to the old one. Anyways Thanks alot for all the help and suggestions! I cant wait till I get enough money saved up for this "project" =-) I did some mods to my Wolverine and was pretty pleased with them.....Im hoping to get some good results out of this Warrior. Out of the list of mods that I mentioned in my first post: engine,exhaust, sprocket, air box system what kind of results in your opinion do you think im looking at? Im not quoting anyone but was curious as to what some of you more experienced people think? Thanks ALOT for all your help! I love my Warrior and cant imagine it getting even better! =-)

Unless you have a mechanic who mods up a lot of Warriors, I'd find someone to call like Alba or any 4-stroke builder to see what spings they recommend with each piston.

Wiseco has a 10.25:1 (compression) piston for the Warrior. Supertrapp pipes are real good although some of the Stockers I ride with are treatening to get the DMC. All I know is I like mine.

You never mentioned your riding style, terrain ect...I don't know how far to recommend you to go on the engine or therefore what to expect. But, you can expect to not be able to fully harness and enjoy the power (if it's a lot) before getting yourself some better handling. As for the Works Shocks, I think they are great. I just hope I never have to replace one. They are expensive or I am tight when it comes to money!!

Just to let you know, works shocks are as cheap as they get! You should check out the Axis or TCS shocks, they are about twice as much as works. Of course, they are zero pre-load and geared more toward pro racers, but damn, 750 for the bottom line TCS's.

If you decide to buy the cam, a valve kit is usually recommended, and they will tell you which springs to get. There are two different spring kits, one is for the all around cam, and one for the race cam. The spring kit is determined by the cam you choose. I got my kit from Highlifter
