big bore cylinder

[hrc450er]

im looking at putting a big bore in my 04 trx and all the kits i find have like 11 to 1 comp. im looking for one that has higher compression. but i dont want to spend the 1000+ on like the sparks or ice cube kits. does anyone know if you can buy just the cylinder and get a seperate piston from somewhere else. or what is my best option. im looking at like the 480 kits

Eddie sanders has a 480 kit for 674 and it uses a 12.5:1 comp piston

Or you buy the CW kit and buy your piston of choice. Then sell the CW kit piston. That might be a little cheaper than the ESR kit.

I was running the duncan racing one and liked it..
