Hi,
I am going to rejet my 2007 KLX 250s with Dynojet 2152 kit.
I will keep the stock exhaust and I live and ride between 5000 and 9000 feet.
What main jet and needle settings should I start with if I want to go lidless?
Should I replace the pilot jet?

Thanks in advance!
Tim

 

You cannot remove the lid while the stock exhaust is on the bike.

Install the kit as per the instructions and remove the snorkel.

Done.
