Default 212 build

Hello all. I am building a 212 Im not looking for much power over stock so this is what I have planned so far for it. first I'm using a 3D clutch and I'm going to get a 26mm carb most likely I also plan on getting a aftermarket flywheel and new stronger valve springs. Also the exhaust will be a 1' free flow set up I may use a muffler from a scooter have not decided on the muffler yet.

does anyone have any other suggestions to what I should do for reliability?

How did you plug the holes from the low oil sensor and the governor shaft? I saw in the videos those guys where squishing o rings and rtv, I've also seen the holes used for crankcase vents. I think id rather plug them with copper washers. What did you do?

Might want to tap those holes and put a bolt in them with some thread sealer.

I have done 2 79s the same way with no leaks. That said I did consider it and if I develop any leaks or decide to do a rod and piston upgrade.

Oh I will it will probably be February before I am even close to done on this one. my Wife is going to paint Ol'Blue and Ill have to rename the bike because it is going to have a blackhawks paint theme. I figure if it is going to be 100% illegal I might as well have a paint scheme that the CPD will love lol.

I tapped them and put bolts with lock washers in them.
