Hello
SV has been laid up for few years, dug it out and MOT'd a few weeks ago but it was running like crap, erratic idle, was slow returning to idle when revved and would briefly drop a cylinder occasionally when idling cold. I've stripped the carbs and done the following;
Replaced choke plunger o-rings
Needle's clear
Float chambers fine
Diaphragms fine
carbs balanced
No split pipes
Sliders nice and free
It looks to be fuelling nicely
Now the bike is running like a sewing machine, starts on the button, revs nicely, idles nice and steadily (when hot, its too hot today to get it cold again) but it's popping like mad which makes me think there is an air leak? but I can't find one. The popping isn't effecting the running of the engine so it's over fuelling into the exhaust. Valves possibly? its driving me nuts! I've included a link to a video of it running.
