Awsome product, installed on my 05 crf250 to get rid of the low end bog. not only does it solve the bog issue it starts much easier, and the throttle response is amazing. I dont think it gave the bike any more power it just made what it already had much smoother and easier to accelerate out of corners. Dont try and tune your carb to get rid of the bog, GO BUY THE QS3. Every bike is different so your qs3 might need to be adjusted a little different than the instructions recomend but they will get you very close to perfect.

This has turned out to be an excellent product! I installed the qs3 on a 2002 yz250f and it fit great. The cable was plenty long enough and came with clear instructions. The bike now has almost instant throttle response and no bog whatsoever. I installed it at the same time as an aftermarket jet kit, so getting the exact jetting and carb tuning took a little time, but this bike has never run so good.
The product gets 4 out of 5 stars because as good as The QuickStart Is, boyensen did not include a new pump diaphram or o-rings in the kit, so you are forced to track them down and order them seperately.
The Quick Start Kit does not work in a 2009 YZ450F. The cable is too short and it pulls the hot start ever so slightly from the bottom of the Quick Shot 3. The throttle response when released idles high and then idles down a few seconds later. When trying to jet for this product I am unable to eliminate the back fire. When replaced with just the Quick Shot 3 the bike runs perfect.
