Guys, the 150's tuning is fine. Found the RPM surge and kept it at that setting.
However, bike is harsh above 5k RPM in top gear. Also, there is a very strong metallic noise at 5k RPM. I think it's the tappet gone haywire but it seems to be a bit harsher than that noise normally is. Any ideas why the engine is straining so much at high revs?
Also, could the tyres be a reason? They have about 2000 km of tread left in them and the tubes are half rotten. I don't want to change the tubes now since I am gonna change the tyres in October.
