Hi, new to the forum and after a bit of help, don't know if anyone can throw any inspiration my way?? Have an early RSV 2000 ish, that I've been building since about 2006! Got it almost there around 2010, up and running no problems, never actually ridden, bit of excess oil smoke on start up initially but think that was due to over filling and going through the air box, then it has sat from 2010. Have started regularly from then but then it started running on the rear cylinder only? so it sat since. Have recently been back to it not just remembering how I left it and found the coil wiring on both coils to the front were wired the wrong way so thought I'd cracked it. Made up some new coil +- leads, new plug leads reconnected the tank and fired her up. Spot on again, running like a dream. Couple of days later fired up again and thought initially heard a little bit of a split second stutter but then was straight onto two. Came to it today and it's back on the rear only??? Not tried swapping the plugs as they were new yes ago. But was going to try those maybe? Any help or inspiration would be much appreciated. Thanks.
