1978 CB750 K tank is too large for cafe bars
« on: September 25, 2009, 12:16:56 PM »
Looking for a more narrow tank so I can run clubmans...is there a earlier model that fits that is not as wide? Or, a different model that fits? Times are tough so I am trying to stay away from a $500 fiberglass option.

Thanks,

David

Short fix is to tap screws or JB Weld some nuts onto your steering stops to keep the bars from swinging all the way into your tank. Not sure what kind of clearance you have with that wide K8 tank, so this might not be a viable option for you :-\

My bike is a 77 with a 76 (i think) tank on. If you're building a cafe build and changing the seat, then there'll be no issues.

I stuck a 72 tank on my 78K.
No problem. Just run a little extra fuel line to the right side petcock.

Me, too.

Just about any 750 tank will fit (even the F's - I've tried them). Your issue will be getting the seat to fit behind it as a stock option will no longer exist (at last not to look right). But like Johnny% said, if you're doing a cafe seat anyway, it shouldn't be a problem.

I like the tapped screws idea, Scondon! I'll use that on this cafe I'm starting next week. Thanks!  :D

I was going to tap screws but an even easier solution is to get 2 small hose clamps and tighten them over the stop posts with the thick screw part providing the extra height.  Works great.
