I have a 2006 Vulcan 750 that has 16,000 miles. Never really had a problem until last month. I set it up for the winter in my garage. Added gas and a stabalizer (sea foam), change the oil and put the battery on a trickle charger. Yes it got cold this year in Arkansas. I clean the plugs, changed the oil, drain the carburators and gas tank and put in new gas. When I tried to start, the engine sputtered for a few seconds then would not start. I took it to my local Kawasaki dealer. He checked it out and said the compression was bad. Sprayed oil in and compression was higg but then started going down. He said I needed to rings. Anyone have a simplier solution to freeing the piston rings (if that is the problem) without spending $800-$1000 to fix?
