Grubee 4g output shaft clearance

Transmission / Drivetrain - www.motoredbikes.com
I'm looking into putting 2 sprockets on my output shaft coming from my grubee 4g 1b transfer case. Correct me if my measurements are off, shaft size is 5/8" with a 3/16 keyway. There is roughly 1 3/4" from the center of the shaft to the engine block and 1 1/2" from the center of the shaft to the air filter box.

I'm thinking about a 10 tooth output matched to a 48 tooth rear (24:1 overall reduction) with a 14 tooth matched to a 44 tooth rear 15.71:1) beside it. Would give me 22mph with hill climbing capability and 34mph for flat ground and downhill at 6870 rpm. Tempted to throw on my old flywheel and magneto for 41mph top speed at 8300 rpm.

According to this chart the 14 tooth should fit:

Does anyone see issues?
