well the jackass i bought the bike from said he put new plugs in. but what i just found out was he didn't tighten them nearly enough. my bike was running like crap lately so i took it in the the dealer. they started it up and took it around the parking lot and then i heard a loud sound. one of the spark plugs shot out of it's hole and stripped the threads on the engine.

Turns out all the plugs were slowly backing out as well. going to cost me 750 bucks plus 99 in plugs to get it working again. mostly labor to just get the damn engine apart.
