Hi folks.
So my curvy was left sitting outside over the winter (i know I know). When I finally got round to it, it wouldn't turn over. Checked the battery and was completely flat. A few days charging wouldn't bring it around so got a new one. Still won't turn over but the starter relay now clicks again.
What I've ruled out...
Starter switch, clutch (bypassed) and side stand switch as the relay clicks when pressed.
Starter relay as it had battery voltage at input and output when starter pressed
The heavy wire from the relay to the starter motor positive terminal shows battery voltage at the end.
I can turn the engine over if I rock the bike hard enough in gear so it's not locked up.
What I think/observations...
The starter positive terminal is in horrendous shape with rust. If I scrape through it I can still get battery voltage but its practically falling apart...and it can spin pretty freely in its gromet which is also pretty torn up.
The voltage doesn't dip when I thumb the starter so I'm pretty sure the starter isn't binding up...it just doesn't see the battery?
The starter motor case is connected to ground.
Before it was parked up the starter sometimes sounded like it was grinding or rasping as it was winding down after the engine started.
I haven't removed the starter yet as I've nowhere to store the bike with bits of it missing lol but I could spend an afternoon, take it off, run any tests you guys think I need to do, and throw it back on again.
My assumption is water has got into the motor and corroded the brushes or contact points or something. Sound reasonable?
If that's the case I'd rather buy a new starter than try a refurb kit as I've no space to work on it. I'd be happy enough to bolt in a complete assembly.
Is this replacement suitable? I'm confused about how the pointy flywheel is somehow different than the curvy but this listing says it's compatible with both.

Cheers for any insight folks and apologies for the large post. Trying to get as much info down as possible.
