how much power will a +4 swingarm steal? will it be noticeable. i know anytime you add weight to the parts your engine turns it will rob power. that's why there's crankshaft power and rear wheel horse power. anybody got ideas for lighter sprockets and chains in that length? i prefer not to use sidewinder. a tooth broke off my raptors $50 12 tooth and the guy said that was expected with that much power. whatever. i hope they don't make sprockets for zx-12s and hyabusas. thanks in advance.
