Bike wont start

mickj · 20-04-2023, 09:47 AM

My Bike won't start up on the tit. Replaced the battery with a new 280CCA LiFePO and it still wont start. The starter motor cranks up until (i assume or that's what it feels like) a piston reaches full compression and stops. I have stripped out all associated wiring and cleaned them up but it make no difference, any ideas out there of what to try next?

can you find any fault codes on the dash menus?

I had this on my 12R, cleaned the earth points and ring terminals. The one on the left hand engine case was grubby

No fault codes and all terminals are clean. Stripped and cleaned the starter motor and bench tested it, all okay, bugger still wont start.

Although you’ve replaced the battery it might be worth attaching jump leads and giving it another try….leave car engine running….I had “issues” with a brand new Odyssey battery on a Guzzi some years ago…..old neighbour suggested the leads trick….started perfectly on the button…..Odyssey was reluctantly replaced and all was good in the biking firmament 😀

Bypassed everything on the bike by connecting the starter directly to a battery, engine turns over fine. Does anyone here know where I can get new leads made up?
