Okay guys I'm new & this is my first post, I joined cause it seems like a great site with alot of help,info,and it's always fun to check out other people's quads! That being said here's my question... I've been doing alot of research on bigbore kits and I can't make up my mind. I own an 01 blaster that is pretty much stock except the wheels and a powercore2 silencer, she seems a little slow for me now so I'm looking to upgrade it. What's better between the following 2 kits...(vito's 240cc big bore cylinder kit) or the (factory 7 airsal fire-breather 240cc big bore cylinder kit)? I realize with the fire breather kit I will have to use racing fuel & all, but just how much of a power difference will it make over the Vito kit? Is it worth putting the extra $500 up and then spending all that money on race fuel everytime I wanna ride or is it not that big of a difference? Any info,help,advice, and comments will be appreciated! And if anyone has either one of these installed let me know how it runs and all the pro's & cons. Thanks guys!
