Backfire when throttle closed

My idle varies w/ weather conditions, but I keep it at about 1200 rpm on my tach. My GeeZee idles lumpy at 1000, and seems to be happiest at 1200 rpm. Also, as a side note, my mc guru says that a low idle in hot weather may result in bearing failure (or excessive wear) with less than recommended oil pressure at a lower than spec idle. No prob if moving, but get stuck, and you could overheat. Mr. Suzuki says 1200 ~ 1300, and Father knows best. (PS; I use the $50 tach recommended on site)

Oh yeah, those pop-pop-pops after a drop is usually a minor leak from disturbing the header to cylinder head seal. It may or may not heal it self after a few miles with normal running carbon build up. If not, replace whatever gasket/donut is used at the joint, and don't drop the MF anymore.
