So far so good

I bought this for a 2007 Ktm 450 exc, at first I wasn't sure it was working the way it should but once the bike warmed up it seemed to work! I only have one ride with it so far but I can't see any issues in the future.

Seemed to help the throttle response and didn't fix issue 100% but it is better then what was stock. I would recommend.
P.S. the support team at moto sport was over the top, very knowledgeable.

Ive personally ran this on every carbeurated bike ive ever had that they made it for. Cant solve a problem with bog on your bike? Try this part and the right jetting specs and its the closest youll get to fuel injected throttle response and no low end or sudden crack of the throttle bog.

Was decent but was expecting more

Installed this on my SX450F and it helped the bogging issue a bit but really was expecting more from it.

Tons of power!!!

I have a 2006 crf250r that was bogging like crazy so I ordered the boyeseen quick shot 2 to see how it would go. After it was on I was amazed. The bogging was gone and the power increase was incredible. Got about 4 hours on it with great results. Only issue is that my valves didn't like it and I bent one due to the power increase. (Valves were stock and 7 years old). Great product already recommended to my friends.

Best $90 part ever

I just put this on my bike like an hour ago. After you get the fuel mixture dialed in, you're left with an incredibly snappy throttle response and more power than you'll know what to do with. I didn't even think I had a bogging problem until I put this on! Greatest $90 I have put into my bike.

Installed on my 2011 WR450 and my sons 2006 YZ250F. Must do as instructions say and replace O-ring on older bikes. Once you get to the bolts that attach the bowl to the carburetor the installation is easy. Re-jetting not necessary, but proper jetting overall is a must. It helps with hot starting and does smooth out throttle response. Hard to tell how much performance increases. Based on easier starting and better throttle response it is worth the cost.

Question: What all is included with this? Does it come with the seal and spring?

Question answered Over 5 years ago
Answer: The Boyesen Quick Shot 2 replaces the stock accelerator pump cover. The internal spring, d-ring, o-ring and diaphragm are intended to be reused. You'll want to order these OEM parts if signs of wear are showing or happen to be missing.

Question: Is this product hard to install?
Question asked Over 10 years ago
i was wondering if this product was easy to install or if it was more dificult
Question answered by james718

Question answered Over 10 years ago
Answer: This would be on the more difficult side. The directions that come with this part are very specific. Here's a little tip though, I don't think the instructions say this, but remove the whole float bowl from the carb, this will make the installation a lot easier. The hardest part with this job is getting the carb off or turning it sideways to get to the screws holding the bowl on.

Question asked by Fabricator450

Question: Does the quickshot come with the gaskets seals and diaphram?

I specifically need to know if i have to buy the whole OEM diaphram kit with the stock cover or does this kit come with the diaphram and seals. (I need to replace the diaphram either way.)

Answer: You might want to double check it just to be on the safe side. Normally the changes will be pretty minimal as far as jetting goes.
