Well I got my KLX250S last week, bought all the part for the mods,
Got it done last night, Man I'm happy, just love it now.
I wanted to thank everyone for all the great mod info,
I did a lot of surfing and studying on here,
So with only 10 miles on my bike I have drilled the slide 7/64ths
drilled the air box to 3/8ths ( boy that was fun )
Took the smog off, removed the snorkel, put in a 128 main
a 40 pilot ,needle on 2nd notch, air fuel screw out 2.5
and added a Two Brothers slip on.
I'm a happy camper now.

Thanks again
Mojo

 

welcome to the site. glad to hear how much you like the bike. it definately is better now that you "fixed" it. now all you have to do is break it in right. you know about the mototune method right?

 

welcome my brother..................ride naked..........and party hard.......

 

welcome...good mods..are you dropping a tooth on the CS sprocket as well?..it's worth it.

 

careful with the 40 pilot, it made my bike run rich down low.... so i went back to the stock pilot.

 

Thanks for the comments,
Yes I'm breaking it in according to Motoman.
I'm riding mainly at sea level, maybe the 40 will work, not sure, but I don't want to take it apart again,
at least not for a while.
I just changed the oil and filter at 20 miles so I'm off and running.
