1992 Nighthawk 750 cafe/brat build
« on: December 03, 2015, 11:49:24 PM »
FYI, this might be a lengthy thread. Im going to take my time on this build, and learn as much as I can. The info for these bikes are not as plenty as others.. I am headed in a cafe/brat direction..

I am about to start on my build. I picked up a non-running 1992 750 with 48k miles, for $800 and got it running the same day. Turns out it was a clogged air filter. It runs fine now, with no filter, but its only been 2 days. Ive been searching and found out that pods are no good. I want to run velocity stacks (with screens) and a 4-1 exhaust. The builds for these bikes are few, but some have attempted and succeeded. I just found out that the Walking Dead bike is also a 97 CB750. My plan is to model from that and a cafe build I saw. I plan to add a kicked up hoop, velocity stacks,, 4-1exhaust, upgraded forks (not sure which ones yet.. depends on budget and availability), and possibly a longer (or aluminum) rear swingarm. Im thinking about the XS650 tank or a CB400, and will go the POR 15 kit if needed on the tank..

Anyways, here is my project. So far, Ive just removed the plastics and turn signals.. havent attempted the tank yet.. but I dont think it will be difficult.

not much progress recently. Havent even chopped the rear frame yet. But soon.. Hoop will be ordered and velocity stacks ( Mikuni KRS-002).

In other news, I picked up this front end. 05/06 GSXR1000. Going to order fork conversion bearings, from allballsracing.com

and this post brings us up to the current date 12/4/2015. Test mounted the GSXR1000 front end. Its a nice upgrade, and gives the bike a much better stance.

Since you've obviously done some research in order to learn that pods are no good/difficult, why do you think that stacks are going to be any better?

Ive realized that stacks are not going to be easier than pods. I will be doing pods.

Yes, the other bike is my 2014 FZ-09

Looking forward to your progress

Could you list steps how you installed Gixer forks? Any mods that must be done to fit? Or was it straight bolt on.
I love that mode a lot.I value handling above everything since generally I ride fast.
Thanks

the original nighthawk steering stem needed to be pressed into the GSXR lower triple. I did not do the pressing, but my buddy told me that he had some tubing that also needed to be pressed in the bottom, to expand the nighthawk stem to fit to the GSXR lower triple. The GSXR stem is about 1.5" shorter than the original NH, which is why it needed to be swapped.

Currently I have it in a "roller" stage, where now I am able to move the bike around easier. I still need to order the bearings from allballsracing.com. This is how she sits now. Will be ordering pods, rear shocks, and an XS650 tank soon.

no reason. I am just finding them reasonably priced. The original tank is way too big.

There hasnt been many updates lately because of the holidays. But that will be changing soon. Thanks for the interest!

Hello, I have been actively searching for a bike to build.  My issue is finding a bike cheap enough to warrant me being able to tear into it and build it.  any suggestions as to where I should be looking, Websites? Locations? Salvage Yards?
Love the build, planning to do something similar.  Keep up the posts!

I found my bike on craigslist. Id check your local craigslist before going to ebay. Another place that might be worth checking out, would be a salvage yard. Unfortunately for me, there arent many close to me.

Good luck on your build! looking forward to seeing some progress

Looking good so far! Have you looked into what pods your getting? I haven't found any for my 99' yet. I just got it so seeing your bike tore down is giving me a good idea of what i need to do. Did you cut the tail of the frame? I'm also looking into doing a usd fork swap.

I'm liking it! I'm planning on doing mines soon also when I do more research and motivate myself to lol. For the rear, are you going with the hoop? I measured mines outer to outer exactly where you cut, and it's 9 1/8". Cannot find a right size for the hoop!

Heyo, excited to see build.
I have pods and I put in the 120 mains. Thing runs amazing. Bike has never been happier. In the process you kinda clean the carbs by default.
I need to install new tires, paint the wheels black, change the headlight to integrated signal type and I'm golden.
of course when the battery dies an under the seat jelly will replace it, but not until she dies.
P.S.
There is nothing wrong with ebay.
you can find a lot of really good stuff on there.
like tires for $60
bars for $20
tail light for $4
4 Mains for $20
pods for $15
ect.

Have you driven it with the pods & 120 jets? Any issues at all? I hear all of the horror stories about flat spots, Stumble, etc.  Would like to hear some real world feedback.

Yes have driven with the 120s. No issues. She pulls hard & screams above 4k.
She does not like anything under 2k. I do have a 16t sprocket up front.
oh yeah I forgot, I put one washer under each needle. #4 Ace Hardware.
It was surprising how well everything worked together.
I removed all the emissions stuff too. AZ is cool about bikes.
how the 0000 do i put pics on here?

You put a washer under the carb needle?? How does that work exactly

It's a poor man's adjustable needle.  It raises the needle a little higher so the needle taper affects the fuel flow at a lower throttle setting.  It'll richen the mixture from 1/8-1/2 throttle or so.  It was a pretty common mod on the 91-03 NH's, especially when someone had done the Hodges exhaust mod. 

In the old forum there was some community knowledge about which Radio Shack washer to use for the best results.  But that info is as gone as Radio Shack itself.
