How much oil is in your pipe?

Every year over the winter, I pull my muffler apart and repack it. I haven't had the pipe off in 3 years. This winter I took it off to do some cleanup and was surprised to see how much oil came out when I hung the pipe up. Now it probably wasn't that much, but by the time it splashed around, it felt like a hundred milliliters (3.5 ounces for you imperialists).

I ride mostly single track and never really get on the pipe so it makes sense that oil would plate out in the pipe, much like the puddle of oil that normally sits in the crankcase. I also use a high flashpoint synthetic oil at 40:1 so there will be excess lubrication.

I do like the fact that the muffler stays oily; it is a breeze to clean up when repacking. No need to do any torch work to remove carbon. I repack every year due to the late season riding in cold temperatures. The muffler never heats up enough to drive out the exhaut condensation so the packing gets damp and loses it's effectiveness.

I don't mind that the Q Stealth is big heavy unit since it does a good job and has a spark arrestor.
 
I agree,wet oil is easy to clean,carbon isnt.i usually throw a little petrol in pipe and slosh about to dilute oil then it runs out nicely. (Into a wasteoil drum)
Then blow pipe out or leave hanging overnight to clear the gas fumes.i reckon the qstealth could be a little shorter/lighter though.plenty of members have cut up to 100mm off without much performance or db difference.pretty sure you can leave the arrestor in place.maybe a little welding involved
 
I bet you drop a full pound when you get rid of the oil soaked packing (that is 2 1/5 Kg for the Metricans) :-)
 
A full pound is less than 0.5kg,as in 2.2lb(thats2&1/5lb) =1kg
If not my 250lb bike weighs 550kg! more than 0.5tonne!(1/2ton)
Dont believe a metrican though,look it up!

Awe Shoot! You are correct! I converted it backwards. Oh well I still have some time to get it correct before the US goes metric.
