I leave Friday for Pitkin, CO and I need to re-jet my 03 WR450. I have the JDJetting kit. The Blue needle is installed.

My problem, I can't find the instructions that came with the JDJetting kit. I found the case, the red needle, the stock needle and the jets that came with the kit, but no instructions. I've searched the garage and came up empty.

Are they posted anywhere? How about emailing a copy?

Thanks in advance.

You could just go over to the jetting forum and ask JD himself. I'm sure he'd be happy to help. :thumbsup:

160 main red #4 works well for 9000 feet in Colorado in the summer. :thumbsup:
