      Hello all.

      I’m Matt from country NSW in Australia and have just purchased a 2008 gt250r as a project to keep myself occupied, When i got the bike it did not start or run ( i paid $300) . After having the bike for a week it now has been fixed to start and run but now i have struck the issue of it stalling at 5000rpm. (this is only in neutral and not tested on the road.) I have changed fuel lines, plugs, oil and filters.

      If you have come across this please let me know what your fix was,

      If we can get this main object out of the way, everything else will be easier.

      Have you taken apart the carb bottom and top covers , take all parts out and dip in ultrasonic bath , or air compressor  (OEM suggested)  and also liquid carb cleaner to clean outside the skeleton body and inside if there wasnt an ultrasonic bath involved? It’s really crucial it gets a clean then retest it.   Then we can further diagnose the next steps in the carb fueling.

        No i have not performed this task, I am mechanically minded but lack the confidence to pull the carbs apart and put them back together again and have hem perform their task like they should,

      Is there anyone local that can take your carbs off and do cleaning to em in the methods i described above?

      There is also a tutorial on this forum called  Main Jet Tutorial , use that as a guide on how to remove the carbs off the bike and  how to put them back on after a pro has done a cleaning session on them?

      Youtube is filled with many tutorials on how to clean carbs in general bikes but i would caution to take everything very slowly due to the fact Hyosung parts can be tricky to get instantly in some regions god forbid anything gets missing
