Hi dear Kawasaki brothers.I have a serious problem.Well pretty soon , a few months ago I bought Kawasaki Ninja 600cc (GPX) - produced 1997 december.I like the bike very much, it's very fast, goes well and everything is just fine, except one thing.I cant lift it on it's rear tyre, I mean I can't ride it just on one tyre.I even gave it to some pros.He said it's a little bit hard, when he switches from third gear to secon it almost reaches it's criticam and maximum rpm and he just lifts it for a while but after that it falls back.Please give me advice, may it be from the tyre it's width is 140, the maximum is 160, chain, clutch or anything else.Please advice or I shall stay disappointed.
