Hi all

I have a 2004 EC300, I bought it and have run it for a while. I now want to replace the piston kit, just so I know where I am with it.

I know nothing about the history of the bike or what parts have been replaced.

1. The cylinder is marked 'A' so should I simply fit an 'A' size piston?

2. Are the pistons also marked with a size/letter?

I'm afraid I don't have easy access to accurate bore gauges to measure the actual size of the cylinder.

I'm not looking for absolute maximum performance, reliability is more important to me.

Thanks, Dave.
