POLINI CONTESSA 72CC WITH A STOCK SYM BLOCK.
MY OLD SET UP WAS A 72CC POLINI CONTESSA WITH A STOCK SYM BLOCK. IT SEEMS LIKE IT WAS RUNNING ALOT BETTER WITH RUNNING THE POLINI BLOCK WITH THE POLINI BORE... DOES ANYONE KNOW ANYBODY THAT EVER USE THIS SET UP... I WOULD LIKE TO KNOW MORE ABOUT IT, AND THINKING ABOUT PORT MY STOCK SYM BLOCK JUS A LITTLE.
THANX!
THANX!

I think you should learn to have some patience first, and then maybe someone would help you. You just posted this same thread 6 minutes ago! Get a hold of yourself man.

2) Knock it off with the all caps. See that button with "Caps Lock" on it? Push it.

I just don't see too many Spree Forumistas reporting direct SYM experience. I do realize that SYM engines were clones of Honda's design, so the same rules should apply, but maybe not.
You'd think the normally well-engineered Polini kit would work best with a Polini-matched cylinder head, but possibly not for some reason on your application. I suggest you perform compression checks using the SYM, then the Polini head and report your findings. I know my Corsa has good performance despite a relatively modest CR.

Re: POLINI CONTESSA 72CC WITH STOCK SYM BLOCK
sym blocks have tiny intake and boost ports. Those should be done by someone who knows what their doing. Polini kits need the polini heads I you want the compression to be right.

To get help with this question, you would need to give us just a bit more 411 on your setup. What pipe, carb, jet size, air filter, etc.? Did you measure compression?

I'm tempted to say it's the throttle grip. It's being turned by a feller who's not very good at outlining an issue or finishing a thought. But I won't say that.one more thing, i came up with another problem i put on my new polini kit and it started jus fine. i rode it 15 to 20 mph, but when i tried to gas it more it starts to bog and the exhaust sounds different, but it doesn't die out. when i release the throttle it rides jus fine. what's wrong with it?

Re: POLINI CONTESSA 72CC WITH STOCK SYM BLOCK
Sum-azn-kid the sym boost port is much smaller than the elite port and so is the intake port. It will run with a stock block but your not gonna reach the true potential and tuning is harder. The boostt port needs to be matched
