Hard to start

[Craig54]

The beast is becoming harder to start.
I keep it on a float charger when not in use.
While she turns over easily and the battery is 13.5v after charging I notice the battery drops to 9v while turning over.
Is it because its not supplying a full 12v to the coils the problem?

That could be part of the problem, but I have to ask, ...

How clean are the carbs?

When were the valve adjusted last?

Mis-adjusted valves are one of the primary culprits if an otherwise-well-running bike is hard to start.

Carbs .....recently balanced ride it daily so havent pulled them apart in years but I guess they are clean
Valves < 1000ks

If the valves are in spec and the carbs are clean, ignition is the next likely suspect.

You say the battery is dropping to 9 volts while cranking. That does not leave much for the ignition to work with. Try connecting your bike to your car's battery (with the car's engine NOT running), see if it starts better. If it does, you need a new battery.
