Posting for a friend this time, 2010 Te 250, He stopped me mid ride yesterday to show me that after the throttle was closed the bike's RPm's were hangin up and then climbing up, almost as if the throttle was stuck a bit? Any Ideas I am going to go into it tonight. Thx for all the help!
One of my Carbed bikes just had an issue with the return throttle cable having too much slack in it and the throttle slide would hang at the bottom and not shut off cleanly... Not sure if an EFI bike can hang like that or not .. -- Just to add a few details on this event, the small odd shaped piece of plastic that covers where the 2 throttle attach to the CARB must be removed ... With the engine running, twist the throttle open and then close it quickly ... You will see a slight hesitation of the throttle block NOT snapping shut at the very bottom of its' stroke ... Engine must be running or the block will snap closed as expected. Bump the throttle open and watch the cables open and close the slide and ADJ as needed...
