Doing a case split and swap - do i need to remove gear and drive sproket.

[gusto]

Do I need to remove gear on crankshaft? Do I need to remove drive sproket? Can these stay on during a case split to swap to new case? I know IV seen people leave on the rotor. Heres a pic of my tc bros stand and table my dad made. We had to drill out some mounting holes on the 40 dollar tc bros stand. They were too small or painted in. You might be able to see the hole in bottom back right case and that's why swapping cases.

Crankshaft gear. I flat out tore up my finger after cracking the timing nut I pinched my finger on the neutral sensor. It hurt and used a rubber mallet to crack the rest of nuts. The head nuts were super tight with these half metal half rubber washers. Kinda strange the washers. I gotta say this is a lot more harder than an xs400 to work on. It'd crazy too the stroke is the same on both pistons instead of 180 twin. Didn't know they made twins like this. I was wondering where the rf and rt marks were but there's just one set of timing marks. I'm missing points and retarded and all my wirings not there and components chopped so I think sanity gonna call for Hughes hand built pma.

You can leave the drive gear on the crank.

The sprocket needs to come off because there's a seal behind it.

I have a tool like this. It will hold the sprocket to get it off. It will also hold the clutch basket. The brand on mine is Tusk. There are several other brands that look the same.
