HELP with carb upgrade

[oldtoys72]

ok guys, I got an 83 airfooler and it rips but im a big dude and looking to get as much power out of it as possible on a tight budget, If i had the money it would be a 480 swap or a big bore kit or who knows what! Anyways, I have heard that I can do i few slight upgrades to gain more power such as new reeds and reed cage, running a "naked" air filter, and upgrading the carb. The question here is what carbs am i able to put on this thing? thank you in advance!

on my 82 i used a 38mm carb boot from a 600 yamaha sled with a boost bottle port, and a 36-38mm keihin pwk off a 90's kx 250 with a open uni filter and it runs great, i didnt even have to rejet it. what kind of exhaust do you have on yours? the new dg's are supposed to make a noticable difference. i will get one when i can afford it

I'm not sure what the pipe is, aftermarket for sure! Haven't had the trike long enough to research the pipe since it has no markings on it. I did however find a small stamping on the head pipe under the gas tank that says "sanken" I think it was, no clue about whether that was stock header or what!
