I bought a 2007 klx250 and i don't know much about mechanics. Can someone please tell me what are the basics when you want to modify a bike?

Thank you.

 

2007?

 

Yes, 2007. I went to my local dealer and there is no more 2006 available in quebec.

 

Congrats on he bike. FAQ. and use the search at the bottom of the page.

 

Is there any differences in the 2006 and the 2007? Like is there a kick starter and are the graphics the same?

 

PICS!

 

For specs and pics go on the canadian kawasaki website (i am canadian...). I think there are some differences with the american model.

 

Thank you a16tony! I went and read the faq, but can you tell me if i change the exhaust system do i have to change something else or the bike will run good with only the pipe changed (sorry for my bad english, my questions may be not too clear...)

 

If you get an aftermarket pipe you will have to at the very least get a larger main jet, 125 size minimum. The general consensus is to get a 125 or 128 main jet, 40 pilot jet, N1TC needle, clip, collar and the pipe of your choice. If you don't want to mess with sourcing the individual parts a Dynojet kit for the KLX300 has all the parts required minus the pilot jet (which is debateable at this point as well, some change it some dont). The Dynojet kit also comes with a selection of main jets so you can fine tune the carb. to your liking and altitude.

 

Thank you bryanjt. I got another question. Do we still have to run the bike at low rpm when it's new, if so what rpm and how long? Does it make a difference somewhere if i don't do it?
