Nothing but throttle response

A must buy for any four stroke. I put it on my 2007 CRF450R and it was very easy to put on with the very detailed instructions.

If you have stalling problems with your CRF450R when you gap the throttle quickly, this will solve your problems. instant power to the ground

Great buy

the quickshot accelorator cover really increased the snap on my bike it also gained a few ponies in the bottom end :) if you dont think your bike has the snap or response BUY THIS PRODUCT!

Question asked by Leffer

Question: Boyesen says it fits the yz450f 2009 and you say it doesn't, what gives? It looks like someone else in the Q and A installed it on an 08. If it fits all FCR carbs why wouldn't it fit the 2009 yz450f?

Answer: I've reported this error in fitment. I did however find that Boyesen Quick Shot 2 Accelerator Pump Cover is available for your machine.

Question: Should I get this if I’m not having any idle or bog problems and just want a little bit more power? I’ve heard this is EFI for carbonated bikes. Is that true?

Question: Accelerator pump cover
Question asked Over 10 years ago
does it bolt directly on to the carb? or onto the water pump cover? it seems as if it does to the water pump cover. does it come with everything to install it?

Answer: If you bike is a newer 4stroke dirt bike, than your carb will have an accelerator pump. This is a specially designed pump that replaces the stock one currently on the carb. This part has nothing to do with the cooling system.

Answer: Boyesen offers a different accelerator pump cover for '08. It's referred to the "check valve model".

Answer: Sounds like there is a sealing issue. Try pulling it off and make sure everything is set properly as far as a gasket or o-rings goes and try and reinstall it. If it didn't include a gasket or o-ring with it you must use your stock one. So maybe you just need to replace whatever is on that cover. Just try and trouble shoot it.
