i have a 1999 warrior with only an alba action pipe kit on. WHat mods should i put and do to my warrior in order to race in motocross. i dont want no costly mods. I am thinking of puting a wiseco high compression piston and works double rates. Will this really help. WHat does the high compression piston do. I really need more acceleration. What about the sprockets.

 

well, ummm, racing and cheap really dont go together(that i know of). The high compression piston raises how much the piston compresses the fuel air mixture in the cylinder. Im not good at explaining stuff like that in detail, so i'm not going to try. If you get a new piston, look at a new cam ($100 from White Bros., after you send yours in exchange), and a bigger carburetor ($200 or $379 from White Bros, the 379 one has an accelerator pump, the other one doesn't). Stiffer valve springs wouldn't hurt either. I don't know about the sprockets, I just put a 12 tooth front on, and I don't know how much I really like it yet since I haven't got to ride it but once. I can definitely tell that I've lost speed, but it does accelerate quicker. Works shocks are good, although I would get the rezzy with any I got, and since the triple rates with the rezzy are only $50 bucks more, I'd just go ahead and get them.

its going to be pretty hard to be competitive with a warrior because they are pretty ill handling and very heavy, you might want to consider selling it and purchasing a 250R. You can be competitive with the R with a set of front shocks and some mild porting. Eventually after dumping all kinds of money into the Yamaha and you getting faster, you'll need an R to advance anyway. good luck!

Before you start doing any mods on your bike, check your local regs out. In my area you are not allowed to do anything except handling mods, without running in the modded class. As an amatuer racer on a budget, you probably cannot afford to run with the modded bikes. Dont bother getting a new bike right now, most races have a 2 and 4 stroke class, which the warrior would do alright in. Once again, check your local regs though, they might just dump all 350cc quads in one class and there is absolutly no way a warrior would keep up with a banshee. Do some research as to what you are allowed to do, then come back and tell us, and maybe then we can give you some ideas. Until then there is not much more that I can tell you.

 

The best advice I can give you about racing the warrior...Is to leave it alone. You already have a pipe. Shocks would help..But beyond what you want to spend.
If you have never raced before...just do it...go to a local race and see how you do. Chances are that you are going to like it and eventually want a quad more suited for racing.
I'm not trying cut on the warrior...I had one and loved it. but it would cost you alot of money to make it a full race quad (at least for MX).
I see many guys racing warriors here in NY...they do OK...But because of interest in this area. All the quads are lumped into one race. So I'm not sure about the regulations on mods.

leave it alone...give it a try. You will know after the first race what you need to do.

If your idea is still to mod it up..then....
Pipe(you already have)
cam
valve work
piston
shocks
A-arms
sprockets
axel
pro design filter

I'm sure you already know...theres at least 3000 worth of mods right there alone.

 

were i am going to race it has 3 clases, a,b and c. The c class are the novice, any kind of atv can go in and on every class you can do as much mods as you want. In the c clas there are raptors, banshees and blasters. A guy in a blaster is the one that is winning. I will get in in 2 months. The a and b class are a-350cc and up and the b-350 and under. Since i will put the piston, how long is the brake in period.

 

You can safely break in a new piston in a day if done properly.
The piston will come with a set of guidelines for break in. Usually it is something like run the bike for 15-20 minutes at no more than half throttle...let it heat up good and then let it totally cool off.
Next run...pretty much the same thing with short blips past halfway on the throttle. let it cool again.
Eventually start staying on the throttle longer and harder and thats about it. I would change/check oil during the process too.

Of course many people have different theories on break in...Some claim not to require any at all.... Just don't be hard on it from the get go.
To be honest with you...all the pistons I have replaced where on my 2 strokes...with the exception of a cam change/valve adjust in a warrior...I guess you should check with a four stroke guru to see if I'm on track.

 

Where you race sound similar to where I race. Our C class is called Quads I. It is any 4stroke, and Blasters, meaning 2strokes under 250.

Quad II is 250 2stroke and anybody who wants in.

The other is Quad Pro. Meaning you gotta have a very good quad and some skill!

I raced quad 1 last summer. I was beat badly by a blaster. He came in first. He was so far ahead of everybody else it wasn't funny. (actually it was...) I made second place. A DS650 came in 7th. An old modified polaris came in 5th in that particular race. Polaris passed me in the whoops once early in the race, but I could out jump him on the biggies. I think in novice class it is more dependent on how well you ride, than what quad you have. Although, better suspension helped in my case. I could double on the bigger jumps, where others could not. The only reason I did as well as I did was because of that. I can't corner worth crap, and I can't do whoops, I almost went over the bars many, many times. I actually did go over once, during a heat race, and I smacked the back of my head on the ground. I had to race the trophy race after that without puking. I made it through and took second trophy again. My wife had to drive home, I thought I was going to hurl bad, but never did.

I am so stoked for this summer, I can't wait! Racing is really fun, it is worth a try.

 

I know most racetracks require you to have a kill switch and nerf bars..

 

A piston by itself does not make a very noticable difference. It helps out quiet a bit, but for the cost of buying and installing a high comp. oversized piston, you can do some other things that will make as big, if not bigger difference. Not sure if you have a air filter on, if you dont, K&N powerkit is a good choice, Comes with a jet&needle kit from dynojet. Cut your airbox lid, or install vents. I have seen custom jobs that look better than the bought vents... A clutch kit is a good idea, but not neccessary, racing is hard on your clutch though. TIRES are a must, get a set of ITP Holeshots, or my fav. Maxis Razrs. The tires alone will improve your handling a very noticable amount. Shocks are another good idea, but are costly and not neccessary until you are good at racing. Nerfbars and Bumper are another must, They will save your bike, and maybe even you (ever see what happens if someone catches your foot or the front of your back tire with their tire? It can get kinda nasty sometimes. Handlebars are another good thing, not very expensive, but they can change how responsive your bike is, they also help with fatigue. Tether switch is a must, even if regs dont require it. And of course, appropriate safety approved riding gear. Most of these are not ENGINE performance related, but are a good start into the world of racing. Speed and acceleration dont matter that much if you are at a constant 50 mph...
