Hi guys/girls,

I run my bike at two different circuts; one fast with a lot of acceleration, and one tight with a long straight.

Advice from Matt from Tyga is to run low comp, retarded timing and a loose piston for long, fast tracks.

My question is: What are the different sizes for each barrel? I.e. is an A barrel the biggest, followed by B, then C?

If that is the case, then it would follow that I could run a B sized piston in an A barrel, to satisfy the 'loose piston' requirement. Similarly, I have a spare C cylinder piston, can I safely run this in a B barrel?

Or are they not in order? Can someone in the know clarify this for me (beyond the basics of what piston matches what barrel etc)?

Cheers!
