I agree yota, fuel injection would be nice, but it costs a lot more to tune [img]i/expressions/face-icon-small-wink.gif[/img]

 

Thats awesome Chris cant wait to read more!!!!!

 

HERE is a link for pics from the build showing the machine work performed.

 

Tuning is the cheap part, the rest of the componets is were it gets you.

 

no i mean like a PCIII they run like 400.00 instead of 5 dollars a jet or 50.00 for a jet kit

 

<div class="FTQUOTE"><begin quote>If you go with too large of a carb then ya you punch it and it will just bog. The raptor carbs vacuum slide would prevent that and the dirt bike carb has a accelerator pump that prevents a bog</end quote></div>

Back in 2000 Polaris changed the SP500,s 34mm carb to a 40mm to make the 500 H.O. and they do not bog, they also put in a performance High duration cam so maybe that off set the bog in some way?

This 488 kit also came with a hotter cam or is it stock duration?

 

no its a hotter cam, and valve springs.

 

Does that dirtbike carb have an accelerator pump? Years back, I tried a Mikuni slide carb that was a Warrior "race" carb, a roundslide. With the quad in neutral, it had great throttle response, but in gear, it bogged badly until the flow caught up with it, the top end was awesome,idled and ran great, but without the manual clutch to allow more rpm on takeoff, the lack of an accel pump made this a bad choice. I sold it and put the stocker back on. The 350 Raptor carb sounds like a good start, eBay should have some for a decent price, I have also heard of the Z400 carb being used by a guy racing his 2000 350 Wolverine, read it in Dirt Wheels several months ago. I have been thinking of a BB stroker kit for my tired old Wolverine after reading your results. What compression piston are you running, do you need race gas,or just premium?

 

yes it would have an accelerator pump in it.

as far as my piston is 11-1 compression ratio. I run premium pump gas. I was told by one of the guys at the shop that if I wanted to put some octane booster in a tank I might notice a difference in that too.

 

I bought a z400 carb because they are so cheap just to see if it would work and with out tearing both carbs down to swap the throttles it will not work. The fuel tank on the wolverines hangs down to far for the throttle cable to work. The fuel bowl also on the z400 carb would have to be swapped out because it is too deep and it would hit the starter. Ctausa1 the FCR carb that you are looking at using might be to tall and too deep to work. The raptor 350 carb is the same size as the z400 but it has the correct throttle housing and the correct fuel bowl. Im just unsure of the inlet and outlet sizes.
