Reply To: GT650 Comet EFI 2010; Stalling issue at idle after revving Apr 2, 2022 at 6:45 AM #7255 Simon👤 Member Topics: 1Replies: 353 I’ve had a little dig about & the tps voltage should be 1.02-1.22v throttle closed & around 4.26v fully open so at 5000rpm it would be between those readings, it might just need adjustment by the sounds of it.
