Is yours a California model?
CA model, all 4 Suzuki's I have had have a hick up, every now and then in the beginning of a ride. Can happen in cold weather more. I am told it has to do with the fuel back flow and smog canister. Never got a good answer but the best so far is that condensed fuel in the vent hose causes a small pause in the flow (kind of like holding your finger over the end of a straw) creating a hick up in the flow. Never have it happen after the bike goes about a mile though.
