so i see there are no write-ups on this mod so i thought i would make one myself. all you need is a pen spring, a valve cap, and some tools. sorry bout the blurry pics. lol

pen spring mod:

Step one: remove your carb from your warrior.

step two: remove carb bowl and look for the hole where the spring goes, and remove it.

step three: put a pen spring into the original spring hole.

step four: put the bowl back onto the carb.

DONE!

valve cap mod:

just remove the plastic side cover and find the accelerator pump rod on the bottom right of the carb.

then put a valve cap onto it:

Pics are kinda crappy but good write up! I think its time someone did one in this mod!
 
yea my camera started shitting out on me its bout time to get a new one! i got an old fujifilm 4.1 megapixel finepix cam and it SUCKS!
 
Hold your cameras shutter button half way down and let it focus before snapping off a pic. Might help. If you're too close to focus, move the camera back a bit and zoom in if you can.

Great write up tho, simple and to the point.
 
yeah i tried that and like i said my camera is takin a **** in the cold so yeah... but my quad is already back together so those are what ya get for now!
 
So the valve mod can be done while carb is on warrior correct??
 
i think it is more benefical to do both at the same time because that spring in there is SOO weak.
 
It eliminates the gap on the accel pump. It makes the throttle response better.
