Hi guys, I`m a new rider and as a first bike I decided to go with the Keeway Superlight 125. When I bought the bike 4 months ago, 2000 miles ago. It was riding good. But as time goes by I started having this issue. When the engine got warm, and from stationary position, in first gear, as you release the clutch and you reach that sweet spot where the transmission is suppose to take over. You feel like the chain is skipping, or the transmission is skipping, it makes a clunk sound. It does this 1-5 times randomly and then it drives okey. Other problem followed with this one. As the engine gets warmer it also gets harder to put it in neutral. Any thoughts what might be the problem? Anyone faced this problem before ? I have been changing oil every 500-600 miles. Thanks
