I have owned my klx300r for about 1 year now and really enjoy the bike. Before the bike had plenty of power for me and really enjoyed riding it, but now that I am becoming more experienced in riding bikes, I'm looking for more of a boost out of my bike. As far as I know the bike is completely stock, I was thinking about getting a jet kit with full exhaust. But I have also considered on getting a 33m pumper carb, and throw out the cv carb that I believe the bike has on it. I ride in the 1000-2000ft range, The bike is hesitant, which is not good for climbing steep hills, I'm also looking for more on the lower end for climbing over obstacles (Small fallen trees, rocks, etc...). I don't consider myself much of a tech guy when it comes to bikes and would appreciate someones advice on this.

 

Narrowed it down to TM33-8012 I just need some help on what I need to buy with this to fit my bike or If I can buy a kit that comes with all I need, If anyone can help it would be very much appreciated! Not worried about price tag if you can find me one would love you forever!

 

You may want to post your question in the KLX250 forum since your 300 is very similar. You'll get more input.

I'd think a Mikuni TM36-68 pumper may be something to look at for carby. Bill Blue also makes a bored out TM34.
