rebuild soon.....what to do

[Butters]

ok i have an 01 300ex and its about time for me a rebuild. i want to make it as close to a real 300cc as i can, but still allow for future rebuilds....meaning not having to re-sleeve. so my question is what should i look for?? any help is welcomed. also any info on what else to do would be good. thanks.

The 305kit is a good power gain along with some headwork and a cam. But I can't remember if there are any bores left after that without sleeving:ermm:

thats really my biggest concern is being able to use the sleeve after this is done. i would rather it be a 29* something then for me not to be able to bore out the sleeve again.
