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.

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.
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.
Easy to install throttle response was alot crisper I have a 2004 Honda crf450 and always wanted fuel injection and this is the closest way.
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
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!
My bike started easier and throttle response was more responsive and crisper.
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
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.
On my Ktm 250sxf the adjust screw on bottom did not have clearance on engine case. It snapped of and made it useless.
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 !
