Save yourself a ton of money and effort and just buy a trike with a bigger engine. You don't know how many times I've seen a post like this and people just don't realize what it takes to build a "monster" engine. "Monster" engine parts are very hard to find and very expensive. Let alone the money it takes to modify your engine cases and all the extra time and effort. If you don't already have the parts, and if you don't have a ton of experience rebuilding these engines, and you don't have access to a machine shop that can do this work, a "monster" 90 engine is not the way to go.

heres as cheap as it get for modified 90 engine a regular guy can do under $500
ebay has a few +3mm or +5mm big bore
10.5-1 piston kits $75-$99
cobra header $130 its about all you can buy new or a used header pipe $75
bigger cam $40-$100 ebay or members on here
110 carb new $50 only get the one that says oem std in the listing others are junk!
bore job/ valve job $125?
thats all i can suggest for a realistic 90 build that will still be kinda relieable
