Question about Yamaha Xv 250 Virago S Motorcycles
Seems like a bad earth, check battery connectors, and any earth straps between engine and frame and also the connectors from each of the indicator wiring into the harness.

Sure mirrors, nuts, bolts and screws. Maybe a fender and a bit of other stuff. But for the most part not much will match up and now you have this ugly monster in your garage and your next job is to figure out exactly how you are going to get rid of the da-- thing. Look a bit harder and get a match for your bike. Now you have something worthwhile.
A “very helpful” rating for this answer? Thanks!

Hi and welcome to FixYa,
Almost always, your described problem indicates clogged idling jets. Stale fuel causes varnish like coating which must be removed. This then calls for a carb pulldown, disassembly and soaking non-rubber parts in carb cleaner. In the exploded carb diagram below, the idle (pilot) jet would be # 20.
Good luck and thank you for asking FixYa.

The rubber seals and fittings between the carbs and cylinder head get hard and brittle. They can develop small cracks and also loose the seal they had when new and pliable. This means that extra air gets into the air/fuel mix as it heads for the intake valves. The air that has not gone through the carbs leans the fuel mix and causes the high revs. The seals and fittings will need to be replaced. Dealers have parts in stock for 10 years. Your bike is 22 years old. Google yamaha virago 750 parts also Google vintage motorcycle parts. Babbitt's would be a good source if the '87 and '88 parts match up. They list an '88 and have all the parts in stock except one hose line.

In the event no price is shown on a particular part and/or the notation "Not Available" is in the description, the part is not in stock. www.babbittsonline.com/pages/parts/viewbybrandand/parts.aspx

try removing the spark plugs . if there dirty clean the with a wire brush.. check the gaps on them are the same . might not be a bad idea to get new one.. if that doesent work its probably that your carbs are dirty or blocked.. if you leave your bike laid up too long the unburnt feul in the carbs evaporates and th additives in it remain and turn to goo.... a couple of hours work at your local garage.. wont cost much.. dont mess with them if your not sure

sounds like you blew a set of piston rings. instead of building compression in the cylinder its pressurizing your crank case forceing the oil out the breather into your air box
