What is the best cylinder for a race scooter?

[Moo Moo]

what will be the best cylinder for the racetrack?
the scooter is Aprilia SR, the setup is:

Yasuni C30
Delorto 25mm
malossi ignition
MHR reedvalve with hebo racing reeds
MHR overrange 2005
MHR delta clutch+wingbell

MHR team speed + MHR team crank
MHR bigbore 77cc + MHR team crank
Hebo manston 2 + MHR RHQ crank
MHR bigbore 86cc + MHR BigBore crank

now i have the RHQ crank and MHR cylinder.
I also have a MHR team crank and team cylinder that i recently bought.

so the question is should i use the team setup or put some money on
a bigbore kit? (77cc kit can be use with my mhr team crank right?)

thanks

Are you going to tune the cylinder?
If not i would go for a 2fast4race or a Speed..

The MHR bigbore 86cc didn't put out a lot op hp untuned, i don't know if it's the same case for the 77cc bigbore. ( haven't seen any test with a 77cc )

If you're going to tune it i would go for the bigbore86cc, there's a lot of potential in this cylinder.

Hey moo moo whats your top speed on your sr so far? have you taken it on the drag strip? but like scarrie said if you were going to tune the cylinder get a 86cc big bore kit i would agree with him.
