Out With The Choke

[EXDUNER127]

I AM NEW HERE AND BUILDING UP MY 400EX, DOES ANYONE KNOW ANYTHING ABOUT REMOVING THE CHOKE AND WHAT IT DOES...DOES IT GIVE YOU ANY POWER TOP END ETC.

[Doibugu2]

Don't expect any power gains. Just better throttle response. Go in the FAQ section, they give all the instructions.

[EXDUNER127]

IS IT NOTICEABLE THROTTLE RESPONSE? CAN YOU DO AN OVERBORE ON THE STOCK CARB?

[UglyMotha™]

ya, i had rocky ridge bore my carb to a 38

[EXDUNER127]

HEY UGLY, DID YOU NOTICE A DIFFERNCE AFTER THE BORE? AND WHAT DO YOU MEAN BY SHORTENED R4 EXHAUST?

[UglyMotha™]

well when i sit on it, it does feel faster but i think it's all in my head:huh .......... at this exact second my quad looks like what is pictured below so i haven't had any seat time with it running yet in the picture my exhaust is the stock length but within a week it should be about 5" shorter all you do basically hack the silencer in half and you can find more about that in the faq

DO YOU GET ANYTHING FROM HACKING IT IN HALF, DO YOU KNOW ANTHING ABOUT TAKING OUT THE SCREEN OR CUTTING IT?

[UglyMotha™]

you get a little more bottom end grut some more noise and it doesn't get ripped off everytime you tumble it backwards

yes i do know about hacking the silencer i did my previous one and i'm doin this one

check the FAQ they have a step by step on how to do it

[EXDUNER127]

DOES IT HAVE ANY NEGATIVE EFFECTS ON YOUREXHAUST OR BIKE

i want to take out my choke too, but i use it alot, and what about the snorkle, do you just "pop" it off?

[Steven]

very simpley it is an air obstruction. remove it and you will get less turbulent and faster air flow, which equals better cylinder charging.

On an OEM bike you likely won't feel much but it all adds up. As the flow demand increases with aftermarket mods, I'm thinking this is a more meaningful modification.

Its easy and cant hurt. Check FAQ for directions. Thats where got mine.

I filled the hole with Hondabond and placed a rubber vacume cap (purchased at Discount Auto) over this hole. Its working great.

i think there's a clamp loosen it and then slide the snorkle out but be sure to cap it off as for the choke go for it while your at it replace your pilot jet with a 42 and you'll never need the choke again just pump the gas 3-4 times and she'll fire up every time, least mine does
