Hi. I own a 2001 Honda Rancher 350 4x4 S model . My bike has been smoking on acceleration from the tailpipe blue smoke for about two months now. Just last night, all of a sudden, the smoke got dramatically worse instantly. at that time I shut the bike off and got towed home. The bike still runs great, don't notice any different sounds in the engine, but it fills my garage with smoke as soon as I start it. The bike only has 1200 miles on it and has always had its regular oil changes I'm at a loss. Can anyone offer any suggestions as to what it might be????
