I ride a 2000 YZF 426. Bike was leaking gas when sitting. Pulled carb cleaned float and re-assembled. Ran great but leaking just a tad. Also, when revving out any gear it sputters and cuts out a little. I've never ridden 4 stoke before now and I'm wondering if the bike will wind like the 2-strokers. When this happens I just shift a little sooner and that works fine. Is this normal???
