hi everyone have a sprint st 955i 2000 model keeps stalling at normal running temp. surges on trailing throttle , runs fine as soon as you put the power on. i can stop stalling if i catch it on the throttle had stepper motor resset twice in the last 6 weeks by main triumph dealer where i bought bike from but still stalling . they said they couldnt find a problem but i have asked them to check valve settings and reset stepper . bike now back at dealer to have another look but if anyone has had similer prob and found a solution please let me know. thanks john.
