Bike Model = : 2008 GT250R
Hi. I posted about a month ago that I flooded my bike and needed some guidance (It wont let me reply to that topic) I changed oil and spark plugs etc put my bike back together took it for test ride and it would cut out at 7k and 10k rpm. So I took it apart again to check spark plugs to find the top part of the carburetor filled with fuel. I took the carburetor off and the intake port was filled with fuel too. I took my carburetor to local bike shop and got them to fit a kit I bought from Ali express. Link to kit.

I bought option E.
I just put it back together today and started it. It struggled to start and would only start if choke was fully on. When I got it running it would idle fine but when using a little throttle it would cut out/break up at about 2k rpm (And would sometimes die after releasing throttle) If I use more throttle itll go past 2k rpm and sounds fine. Its only when using a little throttle
Here is a video of what is happening:

I have not been on here for a while, but I had that exact issue on my carby GV125. So even though it is probably too late to help Twap it might help others. My airbox to carb funnels were shot, going hard, starting to shrink, and would not seal. All clamped properly but they let a small amount of air into the system. Result ok idle and started ok, but on throttle input you got what you saw in the video. If you could get it to rev past about 3.5k/4k it would rev up and climb but not smooth. I 3d printed a new set using TPU filament and cured it – been on bike for a few years now and still good. Hope this helps diagnostics for others. If you want to find that air leak spray carb cleaner and watch for a rev rise, might be very slight but that is enough to mess up cv carbs.
