all CHOKED up

[knighttime]

Notice the nice open airway. Put a 42 pilot in your 400 before or when you remove the choke. With the 42 pilot you will not need the choke. Just pump the throttle a few times before you hit the start button, and kinda feather the throttle at first. If you hear any poppin' and crackin' or snappin sounds, it means you aren't jetted correctly.

I really did notice a power and throttle response increase during the test ride.

Good luck,

Mike

What exactly is a rubber vaccum cap and where would I get one? What part of the hardware store sells them?

Nice little.,,,,,How to remove the choke,,,,,diagram. Guess I might do mine this weekend since I have no other plans. What's the time frame on this project Mike???

And do you have to remove the carb from the bike to do this??

Give yourself a couple hours. Don't be like me and do it when you are tired and in a hurry. Get good and loose.

Take off both the side panels, remove the gas tank straps, and loosen both boots on the carb. Pull the boot attached to the airbox out and around. Refer to one off the first pics posted. Now the carb will kinda "float around". If you can get the soft phillips head screw attaching the yellow lever removed, u r good to go. Just remember about the shavings that will fall out when you take off the choke plate.

Also the hole that must be plugged has a 3/8" outside diameter.

You can purchase a rubber vacuum cap from any auto parts store, even Home Depot sells them in those (lame) "specialty" hardware drawers. Get a 5/16" ID cap so it will fit snug.

Rico, you definetly should take the carb off to keep those metal chips out of the engine. You'll be hard pressed to drink A beer by the time you get the job done!

Either this is a really quick job... or some of us drink a little faster.

Well to be extra careful take it out, but I recommend leaving it in. It's much easier that way. And those 2 shavings will fall straight down. Since the throttle is closed, the entrance to the engine will be almost totally blocked. Those shavings should never make it to the engine. When the choke plate is off, you will see the shavings on the bottom of the entrance of the carb. Just sweep them away.

Dude, it takes longer than 1 beer to get the carb off the quad!

dang,,,removing the choke leaves enough room to get a broom in there to sweep away the,,swedging????

So beer before, during, or after the process???
