Well... I finally got the time to run the bike back out to the exhaust shop where they finished up my diamond jim muffler setup.
They ended up bending a whole new pipe for me with the bike there. Fits great. The shop welded a nut to the pipe and then mounted it to the stock hanger instead of using any sort of mount or steel tube (similar to diamond jim's way). The baffle is right after the bend. Again, the shop welded the nut inside the baffle and then threaded the bolt in to hold it all in place.
Next up is painting it and then the chrome heat shield. The sound is nice... It's a lot quieter with the baffle installed. I was expecting it to be much louder, but it's pretty tolerable, and at cruising speeds, seems very similar to the stock exhaust (not highway cruising speeds... but at 45-50).
The best part is that I'm pretty sure the carb setup I went with is pretty good. I'll have to pull the plug to double check, but it seems great. I was a little unsure on the way out to the shop... It stalled. I was thinking that the carb was flooding, but turns out that it just needed filled up. Not riding for a few months got me out of the reserve tank habit! :-P
Next on the list... Get the license plate mount on with the plate... Get wires run down to that and light it up (have a spare led lamp from my Jeep that I'm going to run)... Then wire up the led brake light and new rear turns and it'll be good to go for spring!
I'm excited. The weather is supposed to be nice tomorrow... So I'm planning to ride into work. Still need to tackle a few little projects, securing some wires and all, but it'll make it the 6 miles into work.
