Im interested in getting a few more ponies out of my 09 KLX 250 and am looking at getting a Dynojet kit from the states and getting a header and muffler from cycleworks in Levin.

What Mods have you done to yours and where did you source the parts?

Also have you drilled out the crankcase breather?
I have read a bit about it but not sure whether the gains are worth the potential risk if you end up upside down for a period of time.

Any info would be greatly appreciated

Cheers

I put a free flow pipe on mine, opened up all the jets; now it sounds like it should be banned, goes like its late and uses fuel like a 650!!! About 25km/L....not flash, be tempted to try the ' not open ' exhaust and see how that goes? 7.7L tank only good for 200k, stock pipe/jets should do 220+.
See my spare tank pix.
Seat is a bit more comfy than other 'dirt bikes', but not a long distance comfort item!
Long suspension is soooo plush-it soaks up anything and still is firm enough to pedal her hardish thru windy seal without wallowing!
I like it. A lot. But, anyone in here will happily tell you; that means nothing!
