kraptorkiller Posted August 16, 2005 Report Share Posted August 16, 2005 ALRIGHT GUYS, I AM NEW TO THE BANSHEE WORLD AND I LOVE IT! ONLY ONE SMALL PROBLEM. I HAVE HAD MY 88 FOR ABOUT THREE WEEKS NOW, AND I HAVE SMALL SPARKS COMING FROM MY SILENCERS. THEY SEEM TO ONLY APPEAR AT 3/4 TO FULL THROTTLE AND PRIMARILY COME FROM THE LEFT SILENCER, BUT NOT ALWAYS. I KNOW A LOT ABOUT ENGINES AND SUCH, BUT YOU PEOPLE ARE THE EXPERTS. SO WHAT GIVES? THANKS Quote Link to comment Share on other sites More sharing options...
BansheeBrian Posted August 16, 2005 Report Share Posted August 16, 2005 Have you done a compression test lately? Might be pieces of carbon burning off.Hope it isn't steel or aluminum creating the sparks.I'm a bit uncertain on this one. Quote Link to comment Share on other sites More sharing options...

2twin350s Posted August 20, 2005 Report Share Posted August 20, 2005 buddies 250r was doing that and the rings were comin apart, better tear it down and check before you bust a piston skirt, could also be the left side crank bearing giving up, CHECK THE CRANK EXTENSIVELY, cus if you do a topend job and miss a loose crank bearing, boom ther goes your new top end. either way 40 bucks for a gasket kit to check it out is worth it to avoid 1000 bucks in broken parts, but it aint silencer packing sparking, make sure you pull the stator cover and check for movement in the crank bearings.

RATBIKE0130 Posted August 21, 2005 Report Share Posted August 21, 2005 Were the silencer recently packed with fresh packing? Kind of stupid to pull the whole topend apart if it's only the packing burning off. Quote Link to comment Share on other sites More sharing options...

Cotton eyed Joe Posted August 21, 2005 Report Share Posted August 21, 2005 what? marshmellow gold? they should be a nice chocolate brown Quote Link to comment Share on other sites More sharing options...
2twin350s Posted August 22, 2005 Report Share Posted August 22, 2005 i agree packing does not shoot sparks, and it has nothing to do with spark plugs, i think somethin expensive is getting chewed up. even more so since it is an 89 banshee. when was the engine last rebuilt 1991?
