new here, got lots to ask, but will start with some basics. just bought a warrior from my cousin (i had one a long time ago) for 300 and looking to do some upgrades. read through the cam specs tutorial, but most of it was jumbled together so i had a hard time keeping up with it. saw a couple of posts on pistons, but not really what i was after. i was wondering, what is so bad about the hot cams products? i saw some user reviews on the stage 1 and 2 cams, people say it wakes up the bike pretty good. also, whats the biggest bore i can go without having to put a sleeve in? can i run the je pistons 12.1:1 with the stock head, or do i need a shim of some sort, head work, or similar, and can it run on 93 octane or will i need to run higher? also, whats a good website with the best deals and carries most performance parts needed? lots to ask, i know, but might as well put them in the same post.
