cliverlong Posted September 26, 2015 Share Posted September 26, 2015 (edited) Hi From time to time, the revs on my XV250 seem to take half a second to kick in when I twist the throttle. Now, I'm not expecting superbike responsiveness but it is this unpredictability that interests/concerns me. I have cleaned the air filter (the oil that came out seemed pretty clean to me) but this had no positive effect. Could the carb need cleaning?and .... what's bothering me is I am developing a tendency to really yank the throttle to compensate then the Virago takes off down the road propelled by the power of many horses.

neversaydie Posted September 26, 2015 Share Posted September 26, 2015 Is it a vacuum operated fuel tap? The carb rubber need to have no leaks/splits etc, fuel tap needs to be working properly and clean inside, as does the filter inside the fuel tank, no kinks in the fuel pipes, clean fresh fuel, throttle cables set correctly. Eliminate the easy ones before fettling with the carb Link to comment Share on other sites More sharing options...
cliverlong Posted September 30, 2016 Author Share Posted September 30, 2016 Finally ..... A completely new "Marving" exhaust from WeMoto in Brighton seems to have cured this "hesitancy". Also I am breathing in less fumes when the bike is stationary - the bike is chucking them out the back to the next punter. Clive Link to comment Share on other sites More sharing options...
