Oil Lines Under The Muffler

Took the muffler off for my 300mi chaincase adjustment. Chain tensioner took 2.5 turn with fingers to tighten and 1/4 turn back. Nothing abnormal there. I then took a look around since I never had muffler off. Came up with two rub points. This one is almost through. Is only a vent line I believe but still.

If you rotate the hose by loosening both clamps it will create clearance. I also added a hose to prevent rubbing.

This Oeticker clamp had the crimp rubbing on the rubber oil line next to it. This would be bad if it wore through. I was able to rotate the whole hose to get the crimp in a safe place as shown.

One more tip. Put some electrical tape or a blob of Silicone on spring as so. Then when you reinstall muffler the spring will stay in a accessible position without falling into neverland.

When I took off muffler gasket split. I am going to try reusing since looks pretty good to me. Mine also had 3 bolts. I bet the fourth is for alignment at factory.

man , i never looked at anything when i took off my muffler to adjust chain , looks like i will have to pull it back off to have a look at that stuff

thanks for the heads up !

Anybody remember who was making the copper muffler gasket ?? I'm thinking if the chain needs to be adjusted every 500 miles that's going to be alot of gaskets which I believe currently are not available. Odds are you're going to destroy a few gaskets with this procedure.

Good to know Steve!

I saw you and your little ones heading toward the river on Tuesday.

A guy on HCS had his new turbo burn to the ground from an oil line snafu. I found my injection line behind the muffler almost worn through. Yikes!

My gasket split also. They looked fine. I re-used them.

It looked like I had two gaskets on the joint. One on the muffler, one on the pipe. Then the thin part that split.
I used a bungee cord to hold the pipe out of the way so not to damage the gaskets when re-installing the muffler.

Good tip on the spring. Mine took a flight to never never land. Long magnets sure come in handy.

What about a little high temp silicone???

cannondale27 · Dec 26, 2013

I dont think its needed on gasket. No leaks. Just reused one on there. Maybe it is designed like that.

I put an extra bolt in my muffler flange. Just didn't think it looked right with that extra hole.

For the spring I made a tool with a small hook on the end from apiece of wire, takes only seconds to unhook and hook up the spring. Accually had the tool from the 2 stroke days from use on the exhaust springs.
Good tip on the use of the bungee cord. Don't know what I cut my thumb on, but had blood every where.
