Decided to get a new muffler and tail pipe this morning, really quieted the rig down a lot. Cost a lot more then I thought it should, but I haven't been to a muffler shop in a long time and there is only really one left in my town. Regardless, looks like quality work and it's a lot quieter.
I will say I made discovery last night fooling around with the BII, I was looking at the exhaust and the transmission. I noticed that one of the band lock nuts had backed off. So I looked up the procedure to set the bands and set both of them and locked the band lock nuts down good.
I had noticed the transmission acting sort of weird in the last couple of weeks. I'm hoping a loose band was the cause and getting them set will help fix it.
