I don't get it... I have had the VFR for 5 years... I have been doing my own servicing and tuning...(oil, oil filter and air filter every 5000km) when I bought the bike it was using 8.8l per 100km...(the owner B4 me has a staintune on it and had the fuel pump removed) I droped the niddles, cleaned carbes, made my own custom end can... got it down to 7.2l per 100km (and I got more pones too) 40,000 km later I checked the valves (all were within spec) and synchronised the carbes... got it to 7.1l per 100km... Ok I understand the consumption went down doing all that but now?? At 80,000km all I did was adjust the valves (only 3 needed it) and synchronised the carbes... I'm getting 5.7l per 100km!! The bike still has the power it had... it is running better... smoother... for the past 80,000km it was super relaiable 7l/100km... So what has happend?? has the quality of fuel gotten better?? Have my jets cloged up??
