westy banshee boy

Hey all, love this site. Its helped my truck loads so far. I'm looking to do some mods to my shee. So far I have: FMF Fatty + Power Core 2. K&N Filter in box w/no lid Stock Carbs with 340 main, 30 pilot Boyseen dual stage reed valves Standard bore size. I've done a bit of research and just want to confirm my thinking. I ride 70% dunes 30% trails. I was thinking of doing: Dune port 28mm keihin PWK carbs. (jets unknown yet) V Force 3 reeds Modquad Cool Head Modquad Pro design noss 21cc domes boost bottle and 3/8 reed spacers. My orignal plan was for a big bore kit like the cub or athena but read they were more drag setups. Please let me know if this will be a good setup or if im just wasting my $$ Cheers. Luke.
