Would make a VERY fun city bike, just needs some real fenders...

Also for sale on Los Angeles CL for an absurdly high price: https://losangeles.craigslist.org/la...158782240.html
Looks like you'd need a very large muffler to stick on the end of that pipe (If you want to stay on speaking terms with the neighbors and cops).
Now if some outfit wants to produce a 600 with a big muffler for around $5000... that might be a fun street machine
