Hey guys, I'm a new member from Sydney Australia.

Looking at jetting two KLX250s', an 09 and a 10.

They will be ridden around 500-600m above sea level. Sometimes at sea level.

I want to go with OEM Keihin parts through Kawasaki.

Both bikes will have the snorkel removed, FMF Megabomb header and FMF Q4 pipe.

Should I go with a #138 main or #135?

Thanks in advance.

 

Hey mate. Go with the #138 based on this sheet that WestOzKLX posted (https://www.kawasakiforums.com/forum...&postcount=2):


Go up to a #38 pilot jet too - it's well worth it.

 

Thanks mate, will go for the #138..

 

Actra, what clip are you using with tha setup and how many washers?

Also do you happen to know how many turns on the fuel screw?

 

I actually went the Dynojet kit route rather than using OEM bits. I only used that sheet for the pilot jet part number.

Dynojet 2206 kit with needle on 3rd clip slot, #38 OEM pilot jet, #128 DJ main jet

My screw is the prescribed 2.5 turns out which seems to be perfect for me.

 

Hmmm I did the exact same thing. It's much better than stock, but I still get some what of a decel pop. Maybe it's because the us model comes with a 35 pilot instead of a 38...I think lol don't quote me on it. Well I'll have to figur that out. Thank you for the response good sir!

 

I'm riding at that level, from sea to 2500 and I'm running the 132 and 40
