Are you talking about where the exhaust pipe bolts up to the engine?

What kind of scooter do you have?

Yes. There is a gasket on the engine.

There is an oval type, and a round type.

40 on a flat for a 50cc is not bad. Hills are always a killer for 50cc. How well they do on a hill depends on your weight an how steep the hill is. There were some hills that the best I could do on my 50cc was 20 mph while on a flat I could go 48 mph. If my son, 12, was on the back it really slowed me down. 50cc can be quick but lack the power of the bigger engines.

To get more power going up hills, a lighter ser of rollers would help - say a 4.5 or 5gm set.

Even a new set of standard (original weight) rollers you will still slow down considerably going up hills.

Sometimes it says the weight of the rollers on the package, or call the dealer you got them from. You can also take them to a pharmacy or jewelery store and ask them to weigh them for you since they have the scale to weigh pills or jewels.
