I had one of them do that for years every 10,000 miles or so I'd throw a new head gasket on it as the cylinder walls were all scored and rings were shot it was so bad I ran gear lube in it
it would burn 2 quarts every tank of gas
but what do you expect for 300,000 and a few too many 8000 rpm jolts funny thing it still ran when I pulled it 2 years ago I have it set for a backup great for chasing mosquitoes not too good to follow on a trail ride though
