Duel disk front, rear disc, it sounds like you have an F model. Can you post some pictures? Have you checked the vin number?
It sounds like the master cylinder needs rebuilt.

My title shows CB750K, and my VIN number matches the bike. But yes, it does seem like it is an F model. I think someone layed it down pretty hard at one point, so maybe they rebuilt it with super sport parts.

That sure looks like an F to me. Someone might have rebuilt it on a K frame though. However I would take a very close look at the numbers to make sure that the frame has not been altered.

Is the rebuild kit for the F different than the one for the K model?

The K, and F carbs are the same. I get most of my carb kits from vintagecb750.com

Thanks TOOLS, but I was asking about the master cylinder. Good to know though for future reference.

I think I saw someone post this somewhere here on the forum, would this be a direct replacement?

It would work, but it's ugly, and you would need to find a way to mount the reservoir. I would use this one http://slingshot-cycles.com/products-page/master-cylinders/sloped-front-master-cylinder-for-78-bars/ or the one that vintagecb75o.com sells. They have a rebuild kit available if it is ever needed.

Re: 1979 cb750k

Nice score on the bike Bud... and what a pleasent surprise to find it's a F !!!
You done good.

Not that I would EVER doubt TOOLS1, but I found it odd that the single disc K and the dual disc F models would use the same master cylinder, so out of curiosity I went to the factory microfisch.
 They do use two different part numbers for the OEM rebuilt kits...

MASTER CYLINDER SETS
’79 F model
45530-463-305 (replaces 45530-422-305)
’79 K model
45530-442-315 (replaces 45530-442-305)

But when I went to the Service manual specs pages for each, they both have the same M/Cyl Bore ID and Piston OD so I could see how they would both use the same AFTERMARKET rebuild kit.
Huh, learn somethin new every day!

73 Honda CB350F Cafe' (Gone but not forgotten)

When comparing Honda part numbers, the first set is all that matters. The two part numbers you listed are the same item.

I called a local honda dealer and they looked up the VIN for me. At some point the DMV messed up, it is most definitely an F model, lol. Also TOOLS, I found that same master cylinder on ebay from a seller with 99% positive feedback for $40.00. It looks pretty similar to the one that is on there.  Thanks for all of your help everyone.

it does not have an F exhaust on it... but thats definitely an F model. The F tank and seat would not fit on a K frame. They're different lengths. diggin the black paint on the engine. AND the drilled discs! anyone else notice that??? lucky dog.

Ya Johnnie's right.
It looks like it's missing a horn and sidecovers, that is an aftermarket exhaust,
oem seat and cover, oem paint.  Nice bike.

I am going to meet the guy I bought it from today to pick up a box of parts he has for it. One of the side covers is there, and I am hoping the other horn. I really enjoy this bike. this winter I will get the tank fixed and re painted. I am also looking for an affordable single seat for it.
