Default 1937 columbia replica build and question

This is the Columbia 1937 replica, I stripped a lot of stuff off it and installed a weed whipper gas tank under the seat and disguised it as an oil tank with a custom clear coated decal/ The new fake tanks are welded together so I didn't try to convert it into a real tank, even though I wanted too. I took the easy way out to conceal my little tank that will still get me 40 miles or so, it has a visual gauge I made on the side of the small tank so should be ok. Yes the gas cap on the big tank is FAKE. It was a fun and challenging build and i like the low slung look of a little light weight motorcycle.
HELP... My question is the off set intake was angled way up and my nephew re welded it and straightened the bolt flange for me but it still is angled enough to make me wonder if the float bowel wont fill and run me lean? What do you guys think? See the first and third pict below. I held the camera level to the horizon.
Thanks ahead of time for any help!

a few more picts.
It also does have 3 brakes front and 2 rear, squeeze and Ill never used coaster brake, so it should stop fast if needed. Has a PK80 engine bolted firmley to the frame with wide 8mm studs, CNC 40T sprocket with hub adapter so it should run be smooth. Just needs a 41 chain I need to get at the hardware store. Plumed, wired and ready to go by Thursday.

Thanks Velodrome, I couldn't seem to come up with any other ideas besides just paint it plain black, so I made it hide in plain sight.

Thanks Curtis, Cant go wrong with Black and white. I really want to try a 1952model Columbia tank replica they have out now also, doing the same thing with the oil tank decal on a weed whipper gas tank. It might even look slicker than the black model 1937 replica. Flip the bars remove the rack and chain guard and maybe remove the fenders and add some white slick brick tires.

I just had my son make me vinyl decals for the cheesy looking analog speedo face to give it a vintage look. Here is the result. I will install it tonight yet. Ill paint the glass edge black also so it matches the Columbia paint scheme

Before and after Picts below mine is the white face

I Installed the speedo late tonight ( my peaceful productive time) painted the sides black gloss and added a 3/32" white pinstripe to the side to tie it to the paint scheme. It can be these small details that are both fun and challenging to do as a hobby vs just making it work, and do give a build a quality factor.

I totally done now* except for a greasy chain install, so guess I'm on to my next Build...? not sure yet what it will be but now I'm kind of hooked on these fake tank bike conversions to a lightweight vintage look motorcycle. Its one great hobby for some that costs plenty, but not really that much when you consider that one should at least be able to recoup all cost plus a small amount for labor if the builds are solid and safe and good looking... That is if I ever sold them. Ill probably have to cull a few in the future at any rate.
