hoppedupandcutdown Posted September 5, 2012 Report Share Posted September 5, 2012 Lately my packing only lasts an hour before being baked hard as a brick to the core in the silencer. Toomey T-5s and Motul 800 at 32:1. And I think it's been smoking more,maybe. I think I'm going to blame it on the 91 octane with ethanol, as I know the alcohol raises the exhaust gas temps. I switched from Castor 927 because that stuck the rings in my sons LT80,and the Motul did not.(CP racing did it's motor work and recommended the Mutol)Sold the 80 and got alot of extra oil. The same gas was causing my YFZ450's to lean out at WOT and shut down. Unless anyone has any other ideas? Quote Link to comment Share on other sites More sharing options...

Fastassbanshee96 Posted September 5, 2012 Report Share Posted September 5, 2012 I had the same problem with my r2s. They were brand new and pulled the exhaust about a week into it and there is pretty much no more packing in there. I was running rich as hell before so maybe that is what is doing it. Can anybody explain why being rich would make the packing burn up so much faster. Quote Link to comment Share on other sites More sharing options...
hoppedupandcutdown Posted September 5, 2012 Author Report Share Posted September 5, 2012 I'm still leaning towards the ethanol...Wouldn't that make it rich on oil to fuel and at the same time lean on air/fuel? So, more oil in the pipes and more heat to bake it. Anyone with experience or trouble with not using pure gas? Quote Link to comment Share on other sites More sharing options...
dave5.0 Posted September 5, 2012 Report Share Posted September 5, 2012 Why not try using less oil? Maybe 40:1 or less? Quote Link to comment Share on other sites More sharing options...
