No, I think everybody has skirted around that issue. Its basically all heresay. We go through this discussion every couple of months or so. Nobody actually goes out and dyno's the bike but THEY know its faster than anything so they must have gained 20-30 HP.
Some recommend the BIG BORE, some recommend the cams first, some recommend the carbs first. Its all worthless until someone dyno's their back after each mod, which nobody does.
