badshee Posted August 25, 2006 Report Share Posted August 25, 2006 (edited) Hey fellas, I noticed this problem after a good ride last saturday..It seems that some sort of oil waste is leaking out the silencer..Its not like a steady leak but i notice a build up of residue..I really can't explain it.. I don't think it could be my premix because i'm running a full synthetic(amsoil dominator @ 40:1)..Well with that said has anybody encountered this or is it pretty common??..

jbooker82 Posted August 25, 2006 Report Share Posted August 25, 2006 It is the left over premix oil. Where do you think all of that oil goes that you keep dumping in to your gas? It doesnt stay in the engine. If it doesnt get burned off it goes out he tail pipe. Quote Link to comment Share on other sites More sharing options...
J-Madd Posted August 29, 2006 Report Share Posted August 29, 2006 My CPIs do it too. I leaned out the main jet and they still build up oil. I don't know what else to try. I run Klotz 32:1. Quote Link to comment Share on other sites More sharing options...
