All I've managed to find was a universal one that I think came off of my SOHC but I can't even find the top brackets for it. I must have already let the other set go.
That's the same exhaust that's on mine but mines got a little damage on it. Let me know if you're willing to ship it when you remove it as well as a price. I may be interested.
Still considering a 4-1 unit in the future as well.
My bike seems to be excessively bumpy these days. I rebuilt the front forks several years ago and the rear shocks have very little use though they are probably 2-3 years old now. Have the springs gone to crap?
Pull the carbs are rebuild them, sounds like the idle jets are clogged and the carbs may not be in sync. If you get it wrong the first time, just try again. I'm sure there's plenty of tutorials on web.
Just picked up an '82 Magna with 30k miles, runs but won't idle. I think it was a good price at $300 so I'm saving it for a future project bike. I'm thinking maybe a brat or bobber this time.
The grips came from either Bike Bandit or Dime City Cycles. The mirrors are from Dime City. I had to tighten them very well as they wanted to vibrate loose. Here's the link to them...
I got it from Dime City Cycles, dimecitycycles.com. It's called the Lucas Style taillight. You can get it with or without tag brackets and also in LED.
