Hello. I have 4 stroke '05 YBR125 for commuting and i have some problems with it.
It tops out at 90km/h and the fuel consumption is 5l/100km which is too high as far as i know. What could cause this? I have +1 front sprocket. I have cleaned the carb and air filter, also i installed a new spark plug.
I know that this is a wrong forum, but maybe you can help me out.
Yep, they are factory spec. I also experimented with bigger jets, but they increased the fuel consumption even more and didn't provide any real benefit. No leaks. AFAIK only the newer fuel-injected ones have tps sensor.
