WR450 - 2004 issues E starting

Hey all,

My brother in law has a 2004 WR450 at my place.
its never been a electric starter because its always been a first kicker once warm.They come out with a 130CCA batery as standard. now he wants to see if he can get it starting regularly with the starter motor,

First thing i did was swap my battery into his (150 CCA for my 14 WR450)
It seems to struggle to crank. when i remove the drive gear that connects the starter to the crank, the starter motor unloaded spins no worries, the bike also kick starts no worries once warm.

im not sure if its the starter motor faltering under load, or something post crank drive thats the issue. it is all oiled up, teeth look good
my battery is new ish (6 months old) and my new 220CCA just turned up to go into mine so this battery will stay with the '04.

anyone else encounted anything like this? i dont want to spend +200 smackers on a new starter motor on a hunch

the only thing that can be ruled out is the battery

any input is, as always appreciated!
