I have read about a few people removing the choke. What does this accomplish and is it easy to do?

easy and well worth it. you have to re-jet after removing the choke.

ok so how do you do it and what do you rejet to? Does it make it harder to start?
I like your daughter
go to the faq forum, its there , everything you need to know
no it makes it easier to start when combined with a 42 pilot jet

My riding group makes fun of me for removing my choke. "What are you stupid you going to need that choke." But I'm the one laughing when I fly by them. I didn't rejet and I didn't go with a bigger pilot jet. I just stab the throttle four times and it starts every time.

I just took my choke out and installed a 42 pilot, and adjusted my idle. It starts up very easy now and idles great. Do you have to up the main jet? I heard you dont, I just want to make sure, everything else is completely stock, i run it w/ the air box lid on, stock filter, stock exaust-(for now), I dont think I have to up the main, do I? Thanx

You dont have to, but its a good idea to, so when its cold out your motor will start alot easier. On a 300 stock is a 38, so I put in a 42, cuz its going to be getting cold soon here, it seems to idle very well now. And I noticed a little bit of improved throttle response after removing the choke.
