New idea for vespa case

Really I dont know if this should go in repair or performance because it could be used for both.

I recently opened up the intake window on my vespa case and wasn't paying as close attention as I should have been so I filed it close to the edges of the sealing surface. While trying to come up with a good idea on how ot fix this potential problem it dawned on me that I could possibly mill out the entire sealing surface and have a plug machined to fit.

Then it occured to me that if that was possible you could overbore the intake and fit a larger carb and passably by using shims on the outside of the case adjust the clearance between the sealing surface and the crank.

( I don't know how the crank to case clearances vary engine to engine but if it's like my intake hole being way off center this could help a lot with blow back.)

really for me atm this is just a pipe dream because i have no experience with CAD or machining. But i thought it was a interesting idea that is maybe worth persuing by people with the skills to make it work.

I hope i wasn't too vague or confusing on trying to convey my idea.

If this idea takes off and makes a million dollars I want a cut. LOL

yeah, I'm not sure this is going to work seeing as you need a really good seal. the crank and the intake are matched perfectly. I imagine that trying to recreate that seal will be very hard.

also the crank face is no wider than the old intake, so unless you're adding reeds, you can't go any wider.
