Hi guys,
Have a 2007 CRF 450R(38 hours)and just installed a Tusk adjustable fuel screw(seated and then backed out 2 full turns)and filled the tank with some new VP Small Engine Ethanol free 94 octane fuel.Bike ran perfect before the new fuel screw(original fuel screw was 2 turns out)and VP gas but now has a hesitation between 4500-5000 rpms.Started on the 4th kick and ran it around the neighborhood for about 10 minutes to run some of that good gas through the carb when I first noticed it(never noticed it before),anyone have any idea as to what could be causing it and a possible remedy?
Thanks,
Jeff
