cheeta Posted October 14, 2009 Report Share Posted October 14, 2009 ok so i just rebuilt my banshee with new pistons and rings and got it together and it worked fine for a couple days then just the other day my buddy was driving it and all of a sudden it just let out a big backfire or something(its at about 1:30 on the video) and ever since it got worse and worse the next day i tried to take it for a drive and it would do nothing but backfire untill i got it super hot so i could see the heat coming off the pipes like ashpault on a hot day and then it worked mint and then when i shut it off and let it cool down it did it again but worse my bike sounded like microwave popcorn going down the road. when i got home that day i checked the side that was backfireing (onley the left side was doing it) for spark and it was getting good spark and its getting gas because the spark plug was dripping its just like it wont burn on that side. i put a new adjustable timing plate on at +4 but there was already a timing plate a +4 i just didn't know so i bought a new one. my thought are maybe the timing plate come loose or possibly an air leak. What do you guys think? any thoughts will help heres a link to the video- Quote Link to comment Share on other sites More sharing options...

FREAKSHOW Posted October 14, 2009 Report Share Posted October 14, 2009 I second checking the reeds. My shee did pretty much the same thing. It turned out the through bolts on the v force 2 reed cage came loose and elongated the bolt holes in the center reeds. look at them real close. Just my 2 cents.
