I need a muffler for a 72 650 with 1.5 id.It doesn't have to b pretty,just need to mount an O2 sensor for carb tunin
 
I checked with a couple locals that are know to have exhaust parts but neither have any at this time. Both are to call me if they get any.
 
Thanks!Looks like I maybe done ridin this year.Gotta deal with pushrod leaks,killed 2 batts,and clutch issues,but did manage to put 500 or so miles on er so rings should b broke in
 
Maybe not all good, especially with the rides possiblyover for the year but you should know most of the issues and can now have the chance to address them.

I'll still let you know if either come up with exhaust parts you could use.
 
Wow an O2 sensor for tuning a 72, most of us would just set it up as the book states, play it by ear to tune the idle mix and maybe have vacuum gauges to balance the carbs, then give it a blast to see what's happening on the road, then fiddle with the needle or cutaway as needed.

Picked up a pipe off eBay $43 a little more than I figged.A muff would have been easier though
 
I have a 71-72 reverse megaphone muffler in FL. Where are you?
