Get a ministroker crank and it will clear the ports

or you can shave the block.

Shaving the block would make the port problem worst.

If it doesnt have any extra base gaskets then yea add them till its right, those 50mm kits are usually made for stroker cranks and that pipe is for like 50-72cc if I am not mistaken also stripped sparkplug threads can never be good for performance :P

yes you risk burning a hole in your piston or seizure from overheating and preignition. Under high compression pump gas can explode from the heat and being compressed before the spark even fires especially with the stock head since it concentrates the squish area and spark closer to the center of the piston crown. You can take the head to a machine shop and get it machined out to 50mm and not worry about ordering a new one

Greetings:

Unless you're burning AvGas, don't even start that engine with that high compression.

:blah: :blah:

Don't setup your scooter up like kryptonite, his is a race only setup.

If you plan to just cruise :coolcruise: aim for about 120psi

@Ben
Get ready to have your * handed to you again before the year is over new old superman is making a comeback! :naughty:
