Durability 5/5 Ease of Installation 4/5 Performance 4/5 Power 4/5 Style 4/5

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.

Boyesen qs2

i bought my 2005 Honda crf250r not knowing it had this already on it but after taking apart the carb and cleaning it i noticed it has this. my bike was always faster than the other stock 250's and now i know why.this is a great investment and its discrete so you can run in the stock class and nobody will know that you have this. it helps a little with the bogging issue but when paired with the R&D Power bowl the bogging issue goes away completely

Good tuning product

I ride a 2005 Honda CRF 450X. I have a full FMF exhaust system, with jetting tuning and other mods. This Boyeson Quickshot 2 definitely helped improve throttle response, snap, and added some power. Or it just made it feel more powerful because of better and smoother response. It did not eliminate bogging, but decreased it, and with the bike jetted to pour fuel to the low end, it is running strong. It is a little pricy for what it does.

Solid product

I installed one on my 06 TRX450r. It helped some with response. Still had a slight bog but not as bad. If you wanna get rid of any bog get this and have your quad dyno tuned!

Not that good

bought quick shot for more performance. it didnt improve response as claimed, but worse than that it leaks gas non stop. removed it and put stock back on. waste of $90.00. more mad that it wouldnt seal.

Chicago area

I wouldn't buy this for KTM bikes, it will not solve your bogging problem. This gives too much gas upon acceleration! You need a leak jet or BOYESEN QUICK SHOT 3 ACCELERATOR PUMP COVER to lessen the amount of fuel on acceleration.

Buy it!

Totally fixed the bottom end bog.

Qshot 2

I noticed a small difference. Didn't totally cure that slight hesitation off dead idle. I would say it was probably worth $45-50 range for the improvement. Looks cool though and very easy to install. About 10 minutes

Expensive but worth it

we'll for the money i'd like to get more than a tiny cover and a sticker but.. you do get what you pay for 2 kicks starts cold everytime, one kick hot and pulls the front end from almost stalling in 2nd gear i'd say the bog is gone easy install for the weekend racer or the do it yourself crowd. cant really see it on the bike but the cover does look pretty cool Installed on 2010 kx250f

Great Product

I have a 2004 YZ 250F. I wanted to add some more spunk to my bike. I read great reviews for this product from this site and magazines. This product gives me more power. Its consistant and smooth. It brings the front tire off the ground with ease and reduces the low end bog. I wish i bought this product years ago.

A well built product by a reputable company but did not notice a differance in power delivery on its own. Teamed with a K&N intake and Pro Curcuit exhaust im sure its doing its thing now.

The BEST 4 stroke product period!

This really helps with the starting and bogging, after I added this to my bike I was just amazed at the difference.

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

A: 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.

A: Nope, should be a direct bolt on right out of the package.
Q: Is this product hard to install?
Over 7 years ago
i was wondering if this product was easy to install or if it was more dificult
Expert MotoSport Staff
Over 7 years ago
A: 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.

Q: Does the quickshot come with the gaskets seals and diaphram?
Over 7 years ago
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.)

A: No the diaphragm will not be included or the o-ring seal

Q: Why can't I purchase a QS2 for my 2008 CRF250?

MotoSport Staff Expert
Over 7 years ago
A: The Honda CRF250R '08 uses a different Boyesen Accelerator Pump Cover, called the Check Valve Model. We are in the process of figuring out why this will not come up on the website. If you are in need of the ASAP, you can give us a call and we can place the order for you on the phone. We apologize for the inconvenience, and will have this issue resolved soon.
Q: When installed do you have to change jet settings?

MotoSport Staff
Over 7 years ago Location: Por+land
A: 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.
Q: Why does the one i got in the mail today look different than the one on the web page.. the bottom doesnt come to a nipple shape its just flat on botto?
