I would. The stocker can perform admirably. But, it's outdated, and can't be modified anymore than the above. The 39mm fcr from a yfz will fit, using a raptor 350 intake manifold. I had one on mine, it fits, it's tight and you have to shim out the back of the fuel tank to clear it, the throttle cable fits the stock housing, too. I could not get the damn thing to run right. Tried everything. Now, that being said, it was a used carb I got from a member here, and it was used when he got it. So neither of us now why it was taken off. Could very well be that it has a problem, and that is why it was taken off. It is on it's way to weston as we speak, to see if he can make it work. The 38mm mikuni TM seems to be a nice unit. The biggest prob will be getting a cable to fit the stock warrior housing. It's a flat slide, has accel pump, and is supposed to develope a lot of velocity. Not badly priced either. Another carb option is the 38mm kehein round slide. Don't know how well it does. What cam do you have? What you looking at? Weston, myself, '00 WO YA!, and a couple others like our stage1 hotcams. You can use stock springs with it if you don't have them already. The web .390 is a nice unit, but, you will need HD springs, and hardweld rockers to run it. Megacycle 252x2 (I beleive, and should be .390/.415 lift) will only require HD springs. A few of use here have it, I believe deadlast is one. Ask him about it's performance.
