I came by $1000 free money recently and decided to spend it on upgrading the bike. I have a stock 2009 KLX250. I can spend it all, but I'm looking for the most bang for the buck. How would you blow...............I mean spend the money? Thanks for your input.

 

First things first... where you findin free money, I need some too.

 

Without a doubt, big bore kit + aftermarket pipe/jetting/airbox mod. That will come close to burning up a grand.

Any left over, new fork springs/revalve.

 

Best bang for buck is the 351 kit by a long shot.

I would do:
351
exhaust
jet kit
vortex throttle

Probably have $100 left over, take the wife out to dinner.

 

351 without question, hey man I'm in Bloomington also, southside, right now at work.

 

Any Bill Blue big bore for sure. FMF header/Q4 and dynojet. Kdx snorkel or no snorkel if like vibration and noise on the boys. That will make a grand disapear, have fun!

 

Big Bore all the way. Whats left you can look at exhaust, cams, carb, suspension ... whatever.

 

Everyone's got their own opinions. So you can take away from it what you want.

I wanted more modest mods that I could do myself without breaking the bank. I also needed to buy a bluetooth for my helmet, gloves, dirt helmet, rack, RAM mount, etc. so I couldn't just spent a lot on performance mods. Here's what I've spent and done in the first few months. I know it's no rocket, but I'm pleased with the power and it suits my needs.

FMF Q4 $300
Dynojet 1&2 $60
KDX snorkel $30
K&N air filter $35

 

Everyone's got their own opinions....yes...and they are all of the opinion that a big bore is the best bang for the buck. Your modest mods almost add up to a BB331 kit.

 

Front valve replacement. Without a doubt. It's Freaking Awful in stock form on a KLXs. THEN, do a big bore, jetting, etc. I don't care how much power a bike has compared to how well it handles.
