weird sound at startup this am.
The exhaust sounded like a jet engine this morning.
I am running 80% biodiesel.
I sounded like a butane torch.
I tapped the brake and it went away.
very odd indeed.

That is normal. There is a valve in the exhaust system that partially closes when it is cold to help warm the engine up. I like that sound myself.

yeah I like it now that I know what it is.
I guess I didn't notice last year with stock exhaust.
Throw in a 5" fat daddy and it roars.
