While doing on going research to find a larger tank to mount on the LS650 frame that starts out single tube 1 7/8" for 5" then Y out to 6" for 10.5" finding a larger tank is a challenge.

Having ridden the Honda CB750 in the distant past I thought that I would investigate if this tank (it has a wide tunnel) might just fit on the LS650.  My problem is that there are not any CB750 around to see if this might be a fit.  Various years have the petcock on the right and some years have the petcock on the left.

Any one out there have access to a CB750 (early 70's)tank to see if this might work?

Another tank to consider my be the early CB500.  Any suggestions?

Over on Bert's pages way back Peter the Blacksmith detailed how he replaced the tank on his Savage with the 15.5 litre tank from a Kawasaki Vulcan. Said to be an almost straight, no mods necessary fit.
