Re: SYM DD50 porting project
yup that stock intake sucks.
just cleaning up this case for a customer. he ended up not wanting porting on his corsa and opted for the stock crank route so i just cleaned up his case put the corsa on bone stock:(
did chamfer all ports and knife edge transfer but didn't touch the exhaust.
didn't get the degree wheel out for this 1. but i'm working on a ministroke daytona 72cc setup right now and hopefully post of that build also.
still trying to wrap my brain around that calculator, but then again haven't really tried to take a good look yet. too busy (lazy) to do much now days. i usually just get out the good old degree wheel make my marks and then make my cuts.
more pics coming soon

Re: SYM DD50 porting project
I never learned how to use a degree wheel. The calculator is pretty straight forward. Get a hold of me if you have any questions. There is another tab on the spreadsheet that will tell you how wide to make the port as well.

Re: SYM DD50 porting project
next step match case to corsa cylinder.
dd50 needs more work than AF16, but can still make nice flow.

Re: SYM DD50 porting project
Nice. Is that matched to a base gasket?

yup that is the stock corsa aluminum base gasket.DirtyE wrote:Nice. Is that matched to a base gasket?
lines up really nice with stock af16 but DD50 needs to be opened up a bit to line up perfect.
Re: SYM DD50 porting project
I like what you did with the flywheel side transfer area. I hit that side, but not as aggressive.

Re: SYM DD50 porting project
thanks,
sometimes gotta go through the case to make it just right.
quicksteel good stuff for fill in. resistant to chemicals.

I used quicksteel to plug my oil pump hole. Worked like a charm.
