Hi All, I've got a 09 KLX 250, bought it from a dealer stock standard everything. Once its broken in, and the 1 year warrantee is about expired, I'm planning on starting the mods. So I can budget for it (good things take time) what would you guys recommend as the first few things to do it? (looking at primarily higher speed)

 

street or dirt? what type of higher speeds are you talking about.

 

street... it has enough power in the lower ranges... but on the motorway it just doesn't quite get there...

 

How does 6th gear feel at highway speeds with your weight? If 6th is a little sluggish, drop the front sprocket down to a 13. Jetting and a decent pipe along with more air into the engine will help. Oh and in case I didn't tell you yet, welcome to the forums.

 

What do you mean jetting and a pip? and yup, got a formal welcome in the introductions thread.

6th gear feels limited by the time I get to the speed limit.. room to move before the red line, but the throttle is almost full.

 

Get the carb jetted with bigger jets and get a full pipe for performance. Moe air in, more air out and more fuel its simple science.

 

hmmm. ok. research this I shall. Of course, was only after I posted this question that I found all those links in the newbie FAQ...

 

lol Yeah I just installed my Dynojet 124 main jet and removed my airbox snorkel. Notice a big differance even with the stock exhaust... But once I do the pipe its off to another bigger jet and hopefully she will scream

 

i have a 09 i just got will post pics soon i took the snorkel out of the air box a 2 brothers pipe and a dynojet jet kit stock gearing it is 2 times as good as stock bar end mirrors and just got avon street tires 120/80/18 rear and a 90/90/21 front thing handles great now
