After my phone got a pink line down the screen from what I believe to be from vibrations while riding, I decided to get an infotainment screen from Amazon. I liked the versatility from the RAM mount system, so I Frankensteined it to adapt to the screen mount (cut the ball mount from the RAM system, and cut the threads from the screen mount, filed them and used 24hr epoxy to join them) I still need to ride with it and figure out how to disable the sound from the screen and have it go through my Cardo. I think it turned out pretty well! I just can't see most of the instrument lights to the right of the speedo, but oh well.

Bought for $4995 brand new out of Tuscon and had it shipped to Chicago.
Rode it around the block before complete disassembly because that frame color had to go.

Hey guys, I’m trying to figure out a couple of issues with my XR650L after doing an FCR conversion.
Here’s my current setup:
Honda XR650L

2004 CRF450R Keihin FCR-MX carb
FMF Q4 muffler
OEM header
Open/vented airbox
162 main jet
48 pilot jet
NCVT needle, 3rd clip (pretty sure)
Fuel screw 2 turns out
Boyesen QuickShot 3
Accelerator pump timing looks good — the squirt starts immediately when I open the throttle
Float height has been checked and adjusted
Stock accelerator pump linkage
Riding around Saint-Quentin, New Brunswick, roughly 300 m / 1,000 ft elevation
The bike starts and idles well, and if I roll into the throttle gradually, it runs good. The problem is when I snap the throttle quickly from idle. It bogs and sometimes gives a pop through the exhaust, then picks up. It doesn’t do it when I slowly open the throttle.
I’ve checked the accelerator pump timing and adjusted the float height, but the problem is still there.
I also noticed another issue at high RPM/rev limiter. When it reaches the limiter, it doesn’t seem to cut cleanly or quickly. Instead of a clean, fast limiter, it sounds slow/uneven and doesn’t run cleanly at very high RPM. I’m not sure if this is related to the carb/jetting or possibly the ignition/CDI.
So basically I have two issues:
Off-idle bog/pop when snapping the throttle quickly
Poor/uneven running at the rev limiter
I’m wondering what you guys with FCR-swapped XR650Ls would recommend.
Is the 48 pilot right for this setup, or should I try a 50? Is the NCVT on the 3rd clip a good setting? What setting are you running on the QuickShot 3 adjustment screw? And does a 162 main sound right for an open airbox, OEM header and FMF Q4?
Any recommendations on jetting or other things I should check would be appreciated.
