hi, i have a 00 suzuki 600 ive had it for yrs never had a problem till now.
my bike starts and runs great except for the fact when u down shift or shift into neutral the bike stalls.... anybody know why this would happen??? '
lmk , thanx

 

I would start with the carbs most likely there is too much gas getting dumped in when your not on the throttle 'Rejett kit'

 

raise the throttle speed!! this will fix you problem( 30 second job) loacted bottom left fairing next to clutch cover near the shift lever!
