New to the forum, starting a 76 CB750K restoration
« on: May 16, 2013, 07:47:37 am »
So I have always wanted to build a cafe racer, similar to those that Classified Moto builds, but have never had the spare cash to go out and buy one.  I was able to buy a 76 CB750 for dirt cheap with only 1800 miles on it and I was going to build my cafe out of that, but when I saw it, it was in just too good of condition to hack it apart. I plan on buying another 750 in the near future to build my dream bike out of that.  I have never worked on a motorcycle before (or car for that matter) so all of this is a learning experience for me.   Well enough of the talk, how about some pictures.  I will also add a picture at the end of my other baby.

welcome to the forum! 
OH MY!!!  you found an awesome survivor there, and good on you for keeping it as is!  ;D

download the shop manual from the forum here, and get a clymer book for it, and read up on the maintenance/service procedures.
these, along with the forum, will help you get it running it tip top shape.

I did buy a Clymer and have already ripped the carbs out and ordered the rebuild kits.  I'm getting a little overwhelmed with the carbs but once i start tearing them apart I should be fine.

hamster, go find my build thread (Yolanda the Honda cb750K1). I am a rookie wrencher and 6 months ago never touched a bike, car, or wrench in my life. I just completed a restoration, mine was in worse condition! lots of info here on this site. search search search. I was fairly detailed with my build so check it out and maybe some of it can help you out. I am still having some issues but hoping to get them worked out soon. looking forward to watching. what is that other bike? it looks awesome

That is the cleanest looking original bike I've seen for quite a while.  Good choice on keeping it original!  I would just service it up, install some new tires, and ride the hell out of it.  I even like the bags.

However, if you aren't a fan of the original bike, you would have no problem selling it to fund your "café" project.

I will def check it out.  My other bike is a 2010 Ducati Streetfighter.  It is pretty much a naked 1098.  They reverse the forks to make it more of an upright riding position.  The thing is an absolute monster.

The bike look really good! I have a 76 K6 too. But started the work away from stock look 1980... it was fun then.
Now going back to stock look except for modified engine, 4-1, mikuni carbs with pods. Tank + side covers with fresh paint and all decals, badges cost a lot... :-[

Remove the bags, and front "window".  Bags are Shoei, right? I had a black set used around Europe during the 80's.

Keep it close to stock when your bike look really good. Find another cheaper F1-F2 if you want to make a cafe racer, surgery modifications with no return.

4-1  will not harm the bike when you can switch back to OEM pipes when you want. The seat can also be replaced with the old modification, Giuliari seat.

I regret that I did not buy that seat +30 years ago when it was found almost everywhere for not that much money.

I use Kawasaki Z1-900 mirrors that look cooler and work better. Cheap copies possible to find today, original long or short stems.

Next is another bar, clubman look like old cafe style. I will use that next time. I used drag bar for the last years that was very comfortable. I have a new one just for sure if I do not like the clubman.

That's it, the bike will look good like that. 
You need to change the main jets with 4-1, if you want KN style carb pods, main jets one step further.
My carbs had stock 105, 115 with 4-1, 120-125 with pods.

The CB750 look sooo good with these mods possible to change back to pure OEM. It's horrible to see the TV shows where they rape bikes with power tools and saw making all look the same... as a bad Norton Manx copy.

CB750 K0-K6 have its own charm and soul that look very nice and a must to keep. This is the bike that initiated the Triumph's, Norton's way to the graveyard when people made their choice.

I just started to read your post and looking at the picture and reading that you want to build a cafe bike. I found myself shocked! :o As I was thinking no please not this bike! I'm glad I kept reading the post. Your making the rite move. Finding these preserved machines is harder to came by everyday and you can find another bike to cafe all over the place but to find a unmolested bike with low miles that has been loved and cared for isn't that easy to come by. Thank you for you help with keeping these old original bikes on the road for all of us to appreciate 8)

Thank you thank you thank you for choosing not to molest this beautiful survivor bike.

There are lots of neglected 750's out there that can serve as a base for a cafe, but there are fewer and fewer clean originals.
