Hi,

Bike won't start off ignition button and when bumped idles at 3K, but can hunt when accelerating. Have checked the following and all tested ok
Coil packs
Injectors
air sensor on throttle body
battery
sensor on air box
spark plugs
HT leads
valve clearance (all within spec)

compression on front cylinder is 120, rear is 110. Service limit is 146 so i know it is low. Cam chain tensioner is slack on the spring (ordered, waiting to fit). after pushing it home tonight for 3 miles I need to sort it. could this be an earth fault?

Any help/tips (yes it has fuel) very much appreciated as it very nearly got rolled into a ditch tonight.......
