bobcat Posted August 10, 2010 Share #1 Posted August 10, 2010 My 86 VR will start up normal. I'll let it warm up for a while then take off. The bike will run rough until its fully warmed up. Its running rough longer than I think it should under the guise of being "cold blooded".. Could this symptom possibly be a coil going bad? Link to comment Share on other sites More sharing options...
Venturous Randy Posted August 10, 2010 Share #2 Posted August 10, 2010 The first thing I would do is check the basic tune up items. I would also take a look at the spark plug caps. They can get corroded inside in the resistor and will fire intermittenly. RandyA Link to comment Share on other sites More sharing options...

PapaAl86 Posted August 14, 2010 Share #4 Posted August 14, 2010 My 1986 vr started running rough,felt like running out of gas, with some backfiring. Checked ohms (pickup coils & ignition coils) there OK. Running on front 2 cyls. Any ideas? Link to comment Share on other sites More sharing options...
jasonm. Posted August 16, 2010 Share #5 Posted August 16, 2010 Always remove the spark plugs immendiately when this happens. Then look at them and hit the starter...do you have spark? Or quicker, just carry spare plugs and disconnect from old and connect to spare, hold it against the head...is there spark? No spark it's wires caps or other electrical. Spark Yes...it's carbs too rich. Link to comment Share on other sites More sharing options...
