Better Info and pics:
1969 Bridgestone MII SS
6,700 miles
New tires and battery
Left exhaust is slightly bent, as seen in pic
Petcock has a slow leak when turned to the on position
The rubber pieces connecting the air filters should probably be replaced (as opposed to the current electrical tape patches)
Smokes like a chimney for the first 3 minutes or so after starting, then settles down to the usual 2-stroke exhaust
Again, any opinions on approximate value would be greatly appreciated. The pics posted show the bike after sitting in the shed for about 2 months, without any cleaning, but it does polish up pretty nicely. Its been a super fun bike and after some original tweaking has been pretty reliable. If I had more time I would never even consider selling it, but as I mentioned the offer is from a collector who plans on restoring so it would probably get the attention it deserves.
Thanks everybody, and this website was a huge help to me in the past when I first picked this bike up- thanks Richard!
