Hello! I would like to push my Kawasaki ER5, because the battery is as good as flat. Hupe is no longer possible, light is only flickering. Some fun bird has turned on the standlight in our communal garage. To push/roll on I use the small descent into the garage. I get about 20 km/h speed on it. At the first attempt in the first gear the wheels blocked completely. In addition, it can be pushed with pulled coupling only hard in the first. Then I read that it is best to push in the second gear. Unfortunately, I can’t get it in. After inserting the first gear I can get back into the idle, but from then on I can’t get higher. So the gears can’t be installed in the stand at all. Must add that my bike was now about 1 year unused in the garage. However, I did a round down there every few months, so nothing rusts up. The last half year it wasn’t moved at all. Thank you for your advice. I am really grateful for every help!
