Boysen Quick Shot 3

Installed the Boysen Quick Shot 3 on my 2011 KTM 530 XC-W. I was having issues with hard starting, inconsistent idle, deceleration popping and throttle bogging. Paired the BQS3 with the correct JD jetting, adjustable fuel needle and the bike is now crisp on throttle response and starts easy and has enhanced power that is clean. I would definitely recommend this to friends and family.

Don't touch AP timing screw

The QS 3 mentions adjusting timing screw if it was touched. do not adjust the screw if your bike isn't running bad. I touched mine and it has been a nightmare ever since.

OFF idle bog

Easy to install on 13 crf250x carb, had to remove, was experiencing an off idle bog. will try again later once exhaust is installed and further research. If anyone has any suggestions or has installed QS3, I would really appreciate it. Mods: opened top of air box, 165 main jet, fuel mixture screw, removed baffle in stock exhaust, and back fire screen from air filter. After failed tuning, dropped to a 155 main jet, reinstalled stock APC, back fire screen, and exhaust baffle. This got rid of off idle bog.

WOW

The QS3 did just what they say no more bog witch in turn freed up alot more of my crf 450's bottom end power, pulls alot better out of the tight corners. Great product. Easy to install expect for the fact you have to tear half the bike apart to get the carb out but it was in the carb in less then 5 minutes after pulling the it, fit perfect, looks good easy to adjust, what can i say another awesome product from Boyesen

A MUST HAVE!

I bought this for my 2008 honda crf250r, my bike had the worst bog ever and could hardly gap the throttle without it hesitating even while riding, so i took a chance and bought this product and WOW! Its a night and day difference no more bog whatsoever no matter how hard i gap the throttle, I knew it would help but never thought it would be this jurastic!
If your looking for the fuel injection response look no further this is bolt on fuel injection!

Helped with my bog

Installed on my trx450er and followed all instructions...did a little tinkering and its working great so far. No more removing the jet to change it out....just turn the nob.. any help with tuning is a thumbs up for me

2011 WR250F

I added an FMF pipe and had a horrible flat spot on the Lowe end. I added the Boyesen QS3 and all was well with the world. The bike pulls cleanly from idle to flat out. It also starts well. I could not be happier. I can not give a high rating on durability as I just got it. But knowing Boyesens rep I can give it a guess as top quality as with all their products I have used on my 2 smoker RMB in the 70's.

Carful about clearance

On my Ktm 250sxf the adjust screw on bottom did not have clearance on engine case. It snapped of and made it useless.

Excellent part !

BOYESEN QUICKSHOT 3 ACCELERATOR PUMP COVER works wonders, this part with JD jetting I was able to dial up the performance big time on 06 YZ450F !

I'm debating on buying this product but I'm not sure how easy it is to install. Will it be an easy quick bolt on to my carb or does it involve taking the carb apart?

A: Yes, this will fit your 2003 YZ450F. However there may be other issues such as jetting that can be changed for your elevation and area. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. I would recommend taking your bike to a local motorcycle dealership’s service department to have your bike properly jetted.

A: Without being there to know how exactly the bike is running, It would be very difficult for me to accurately help you jet your bike. There is not a specific setting I could give you for jetting your bike. Jetting can be very tricky, there isn't one setting that will work everywhere with every bike. I would recommend taking your bike to a motorcycle with a service department to have it properly jetted.

A: The Boyesen Quickshot 3 would be great for your 2012 Yamaha YZ250F. Boyesen also makes the Boyesen Quick Start Kit that features an Integrated Hot Start Assist eliminates problem 4-stroke hot start procedure. I would recommend either the Quickshot 3 or Quickstart kit for your bike.

A: This is a carburetor part to replace the stock accelerator pump cover. This has no relation to the oil filter and would not fix the problem you are having. More than likely your oil filter cover o-ring's are leaking. It is very hard to say without seeing the bike but typically this would be the issue. The oil filter o-rings can be found in the OEM parts for your 2008 YZ250f here: http://www.motosport.com/dirtbike/oem-parts/YAMAHA/2008/YZ250F/OIL-CLEANER
