When I first got my bike (550 Maxim) it was tough to start especially in cold weather. Spark Plugs looked decent and had a little under 5000 miles so I thought they were not the issue. However when I changed them the bike then started up with just a quick hit of the starter button. Recently the hard start issue has returned so today I changed them out again. Only about 2k on these plugs. Again this solved the problem and it fires up with a quick touch of the button. The gap was still in spec on the old plugs and they look pretty good. My thinking is I'm running lean and its burning them up? I took some pictures. Do I need to sign up with a hosting site to post them? Also anyone use those sandblaster spark plug cleaning tools with success? I remember my dad using one for chainsaws and lawn mowers back in the day.
