The directions that come with the jet kit are easy to understand and the jets are of excellent quality.

Jets are ridiculously expensive at the dealer. I used these to get the jetting spot on and saved a bundle. I will buy them again for sure.

I used the 07 KLX300R Stage 2 kit on my 07 KLX250S after installing a Two Bros slip on and Uni Air filter and removing the air box lid. Bike runs 100% better. Would be sweet if they included pilot jets.

I was glad to see they had some OEM jets also, they delivered quickly and where accurate in their order. I will be glad to order from Rocky Mountain again.
