Tillotson carburetor 304WX for my GX200???

[Peyote_Pete]

GX200 with stock sized valves, .265 lift .236 I/E duration cam. going to port and mill the head and eventually install bigger seats and valves, will I be happy with this carb???



PS. will I be able to use 1.3 rockers with this cam or will I have a clearance issue???

Nope, that cam will flatten out with ratio rockers, or float the valves. It's best to go with a .300" plus lift cam to start with. Then that 304wx carb would work much better. As is right now it's to much carb for how mild the motor is.

I just bought a .265 lift cam from a site member an hour ago:sad:... What carb would you recommend for my current setup?

 

[Peyote_Pete]

too bad, I like that carb, would have spent the extra $50.00 for a .308 cam had I known.
Honestly, I'm not racing. I just want to go fast (50 MPH+). and I weigh 260 LBS, any expert suggestions besides "buy a real motorcycle"???

334wx would work, or just stay stock and re-jet.
I've got a 334wx that i just pulled off an engine with a .265 cam that ran decent.

Thanks for the reply. Bungle. It was late and i was pretty stoned. I had bought a stock length conrod not a cam. The cam was in my cart but i hadnt payed yet. I guess I should get that. 308 lift cam after all? Im buying a cam today from OldMiniBikes. I just want a little expert go fast advice before I do. Probably wont have the cash to upgrade for a while

The 304 is a very good carb. Learn how to tune it and it will instantly wake up your ride. It'll feel like you just bolted on a second engine. From stock size on up to modified, there's very good performance to be gained. Just dial it in and you're there.

The .308" is a pretty good cam to use. 50mph is a cool speed to run at, and you should be able to run that speed for a good long while.

LOL, the way you say "50mph is a cool speed to run at" makes me feel lame, F:censure:K it, I wanna do 80!!!!

Its always easier on your pocket book to go big right away, than to work your way up and take a loss in funds on performance parts trying to resell them :thumbsup:

 

[minidragbike]

80mph may cost way to much to do
Stick with 50mph, or maybe even 60mph.

Ok. 60 sounds good. We'll see where what iv'e got gets me and go from there.
Thanks for the input.

50 or 60 is plenty enough scare for me......

I am hitting 50 with the stock cam and a pz22 carb. You don't need to go so big for 50, well, in my experience anyway. Nice speed indeed, but I am going to gear it lower, faster than I need to go.
