backfiring means you have an air leak or a lean mixture. Look for leaks at the header pipes or perhaps a crack in the exhaust.
Cold air getting into the exhaust is usually what causes the backfire noise.
You may have a lean engine running situation but the bike would have other issues besides the backfire.
Let me know if you are having any other issues or if it just the backfire.

My 2007 C90t which is the same motor as yours requires 4 1/2 quarts of 10/40wt.
Stick with Suzuki brand oil btw. When I changed to Amsoil, I developed a problem.
