people learn by asking questions
90MM piston, +10MM stroke crank, long Kawi rods will net you 900+cc.
Sleeve is custom for the cylinder, an aftermarket cylinder not stock
Will take your 60 HP motor to upwards of 160 HP if you run it on race gas.
Better be ready for this kind of power.
Honestly, if you are new, unless you are a prodigy, it is better to work up to that level of power or you will just spend alot of time swimming and you won't have much fun.
Better to start off cheap and work your way up.
You can have your stock cylinder ported for sure.
Add bigger pistons to your stock cylinder at this time if you want.
Bump the compression up, if you are up for race gas, bump the compression up a little more.
Get a Factory pipe for it (and learn how to adjust it.)
Aftermarket carbs if you want to spend the money.
"Total loss" ignition if you want to deal with the downsides.
Different impeller(s)
This will get you to 70% of what you are asking, CHEAPLY.
The pipe(and ignition) you can carry over when you step up, your stock cylinder could be sold off to offset some of your cost when you do.
Be careful biting off more than you can chew.
