Had you just refueled the bike when you got the hesitation stalling, just wondering. Several inmates have reported those symptoms when getting a tank of bad stuff. Has it happened again?
Will look at the brake line on wife's 650 this week, spiral hose protector may be the answere for a slight rubbing, used on aircraft hoses when their is a slight chaffing issue
To all going to install Skene P3 lights on the 650 will let you all know the outcome!
