I hate to sound skeptical but that re-jetting thing sounds a little complicated. I need my first tune up done anyway, so i guess it's an excuse to have it done then. Unless, you guys know of somewhere that will walk me throught the process then I am probably stuck apying for it to get re-jetted. Thanks for the input either way. Dacoontz.

As far as the rejetting goes, 4 screws on the bottom of the carburetor and you can reach the main jet. its a little screw with a hole through it with a slotted head. Unscrew it and put in a different size. Turn it over and pull the top 4 screws and you can replace the needle if you want, or just shim the original needle with a small washer or 2, I forget the number used.
Here's a very good walk through on the carb mods.

Do you guys know if anything like new exhaust or re-jetting will void your warranty.

As has been said its not difficult & alot of the trail & error has been done for you via this forum.You can either use OEM KLX300 carb parts or use a KLX300 DJ kit to get to your goal. There is not a lot of price difference but the Kawi parts are a little cheaper. I ran the Kawi parts until I went big bore then switched to DJ.

RE: big gun install 07 klx250s
okay, so I just read that link to HMF about how to rejet. I appreciate the confidece you all have in me but there is no way in hell I am trying that. I am not to comfortable pulling the gas tank and blah, blah, blah. Oh well, but hey how about the core or insert people are talking about. There's the Vortex insert, the race core or the quiet core that I have heard of. Is there one that is better than the other. And if I am going to have the shop rejet my bike is there anything else I should have them do while they are in there tinkering around, like a cheap part that isn;t cheap to install or something along those lines.

Might as well have 'em put in an iridium plug too. It's 8 bucks and wont hurt the bike any...
