hey guys, i just got this sled used about a month ago. its an 02 Zr 800 EFI cross country. now that ive got snow to take it for a test ride it seems to be cutting out almost all the time at 4k right around when the clutch starts to engage. i already did the throttle safety wire elimination by breaking off the center pin in that connector, and i got the new plastic shims for the throttle lever. so where do i start from here. this is my first time trying to deal with an efi sled and im kinda clueless.
