CadillacBanshee Posted December 31, 2006 Report Share Posted December 31, 2006 We changed the plugs on my brothers bike this weekend, one came loose and the right side of the engine lost ALOT oompression. The tip of the plug looked melted. Quote Link to comment Share on other sites More sharing options...
bansheeseat$$ Posted December 31, 2006 Report Share Posted December 31, 2006 It sure can.Creates a air leak and Leans out the cylinder causing holes in pistons and loss of compression.Sorry for the bad news. Quote Link to comment Share on other sites More sharing options...
dajogejr Posted December 31, 2006 Report Share Posted December 31, 2006 Yep...exactly. I'd bet that sparkplug looks like it has aluminum specs on it, too... Tear off the top end now, while it'll still run before you do some BIG time damage!!! Quote Link to comment Share on other sites More sharing options...
alcoholbanshee Posted January 1, 2007 Report Share Posted January 1, 2007 I would also concern myself with why it backed out..........detonation. To much timing, air leak (crank seals), Clogged main jet, too small of main jet, . etc, etc, could be quite a few things! Quote Link to comment Share on other sites More sharing options...
Animalman294 Posted January 2, 2007 Report Share Posted January 2, 2007 No offense, but could also be that someone was in a hurry to go ridin' and thought that it was tight, but really wasn't and ran it 'til it tore up the cylinder.............. :shrug: Quote Link to comment Share on other sites More sharing options...
