    A must have when adding pipe/filter!

    I ride from 0 feet (Oregon Dunes) to 4k feet (Oregon Woods) and jetting performs perfectly! No Guesswork I have added a full yoshi pipe and a k&n filter to my bike. I run with the airbox top on but the intake neck off. While getting the carb off a Z400 Quadsport is a bit of a pain, jetting it using the included instructions was really easy to do and I have not had to mess with it since.

    Good products

    Used these kits for years, have always been great. Wish they would include pilot jet though, but really not a big deal. They are always spot on with the tuning!

    Good Unit!

    Great kit, some of the items are a little different looking but overall do what they are intended to. Fitment was perfect and the carb works like new!

    Works well until bike is warm

    The kit really makes the bike easy to start but once it is hot from riding, it becomes hard to start on the trail. It looks like the main jet makes the bike too rich once it is hot. So, I suspect the idle jet is just right and the main could be a step or two smaller.

    Carb was bone stock on the Dr 650, Ran just good enough to be rideable. Was not dirty fuel was fine. Not much throttle response. What a night and day difference. Totally different bike, instant response. Pulls hard all though the RPM range. Runs actually cooler. Worth the price. ANYONE CONSIDERING THIS FOR THE DR 650, YOU WILL NOT BE DISAPPOINTED!
