Looking for the best bang for the buck hop-ups.
I had a 96' that i changed the gearing on and got
about 67mph on the highway. I am looking for mainly top end. I ride the back roads mainly. Need to
keep reliability!

 

Unfortunately, reliability and high rpm normally don't go together on a Warrior. They have problems with rod failure if they're revved too much.

That said, you can get a decent boost from a small bore kit (365cc), and a mid to top end camshaft and heavy duty valve springs. The whole deal will set you back about $450, and gain you about 20% hp, which should translate to 3-4 mph at top speed (more if you re-gear it).

 

I never heard of rod failure but I'd listen to Pam, she knows more of this stuff than 99.9% of anybody else here. Btw Pam, does that apply to the strokers too or do they use a different rod?

 

Basically, it applies equally to a stroker crank as a stock crank. The thing about the stroker engine is that you don't need to rev it as much to get it to go! With the stroker, you can gear the thing up, so you don't have to over-rev the engine.

Basically, the rod (whether it's stock or aftermarket) doesn't get enough oil to the small end after about 10,000 rpm. So they just don't last very long when they're revved.

Of course, I'm talking just screaming the enigne for extended periods -- jamming the throttle wide open on a dune or hillclimb isn't going to hurt 'em.

 

Well Guys (and howdy Pam) I'm a happy 400cc Wicked Warrior owner. Stroker crank and big bore, cammed, ported, supertrapp, and the only thing stock on my motor is the Carb...

I'd have to disagree with Pam though (GASP!) about gearing up the motor too much. Of course this also depends on tire size, terrain, rider ability and desired ride charectoristics.

I did gear the 400cc warrior up to a 14/40, but also went up to 22" rear XCT tires. Yes I could still pull hills, and for top end it was great (70 mph) but the front end seemed real heavy when trying to pop the front end over an obstacle.

I went back to stock 13/40 gearing and its a whole different story. I can lift the front end and wheelie at will now.

Depending on what (and how) you like to ride, gearing, tires and stroker cranks can make all the difference in the world.

 

wow heapster 400cc warrior!!! thats something i would like to get!!!. Um , would anyone be able to tell me what i should do to my stock warrior first? Im low on cash and its my firs bike. I want to eventually race mx. But in the mean ime ill be off roading and racing my friend on out personal track that were going to build. I also am going to jump A LOT!!! what should i do?
