Newbie '78 CB750 K8 (US) Cafe Build
« on: April 29, 2018, 02:25:34 PM »
Hi all,

New here and thought it would be a great place to share my progress (as well as ask for a whole heap of help).

Recently acquired a 78' CB750 K8 from a chap that imported it from the states a good few years back now with the intention of turning into a cafe racer.

I've included some pics and will share my progress as I go on.

Most of the parts will not be going back on the bike and are in good condition, so please feel free to drop me a message if you need anything.

Cheers,

Marc

Welcome to the forum, looks like you've got a reasonable start point as the bike seems quite good condition wise.

Nice workshop,  even got a sofa  ;)

Hi all - thank you so much for all the welcoming messages!

Just a quick update really... I've started to strip the bike down and still have quite a way to go, but as you can see we're without the seat, headlight, battery, pegs and tank badges.

Have various bits and pieces on order and am considering switching out the tank for a GS650. Would prefer a mid-70's CB750f Supersport tank. But after wasting several hours scouring the net earlier today, it appears they are incredibly hard to find!

Any thoughts, comments, advice very much welcomed.

Definitely going to be doing the 4-into-1 pipe!

I've been looking at the Yoshimura style one from Carpy's Cafe Racers http://carpyscaferacers.com/shop/shop-our-store/motorcycle-parts-accessories/honda-cb500-cb550-cb750-parts-upgrades/cb750-4-into-1-exhaust-sohc/ - does anyone have any thoughts on this or know if anywhere in the UK I can get something similar for the same price (around £600 delivered)?

I have looked at the 400f tank, but it has a slightly sharper angle than the CB750f. The CX500 one does look pretty cool, though. I'll have a play around on Photoshop later and see what I think!
