Gen 1 Cranks but does not turn over

[tlr1000]

Just bought a 07 busa and it will not crank over. The battery wasn’t enough cca so i went out and got a powerful enough battery but still won’t turn over. Fuel pump primes. I can clutch start the bike but even after 30-40 minutes of riding it wont crank over on a hot start.

Hi, welcome along.
When you hit the starter button does it do anything at all?
Do you hear a click from the starter relay?
Does the starter motor turn at all? Ever??
Are you pulling the clutch lever in when starting the bike?
Is the gear position in neutral?
the more info you can give the better . . pretty hard to diagnose it over the internet.

Yes the bike is trying to turn over
Clutch pulled in and in neutral

Maybe semantics is an issue in the description. Cranking over and turning over may be the same thing, the starter is working and spinning the motor but it won’t start, right? It did bump start (you said clutch start) but even after riding it, it still wouldn’t start using the starter right? Some would say it cranks but won’t turn over, meaning it won’t start but I think most would say that cranking and turning over are the same. Firing up using the starter is where there’s a problem right?

I always go back to check the cranking voltage at the coils

Yes this is a a more clear description of the issue, thank you.

Solved it, returned the battery for one with 300cca and she started right up. Lol this is why I post in the new owner section.

I’m not convinced you solved the issue. A 175 cca battery starts my Hayabusa just fine.

If you have not done so measure the voltage at idle and 5000 RPM and see if the charging system is working.

Will do
