Right gona upset the cart here! i know the Tyga kit is a nice set up and works well, in fact its on my wish list, but i sat down and had a cup of tea in someones work shop today (im not saying just yet as i wana see what you guys think) got onto the topic of big bores, i told him about the 300cc kit and he said yup should be good but why not go for a 380cc!!!!!!!! WHAT!!! he pulled out a set of barrles (not NSR) that he's made up (well made to fit) for a friend with a 21 they slap straight on apperantly and he has the pistons as well! there not complete yet but he hopes to have them done soon! what do you guys think has it been done before is it possiable we could go 380cc? lets forget about the crank for a second and thnk about the 380cc, Can it be done?...........................imagine a 380cc v twin!!!!
