The Great Brat Overhaul of 2K15 (update)
« on: January 24, 2016, 03:16:58 PM »
I generally find the term "cager" to be a little too antagonistic for my sensibilities, but... last fall I got straight knocked off my bike by a cager! Zoomed right off, leaving me with a torn up bike, badly dislocated shoulder, some exposed bone here and there.  viol

No hard feelings, really, but in the absence of any viable insurance claim I went to work.

Before:


After:







Tank is from a 1978 CB750K. Seat from Ginger McCabe at New Church Moto in Portland. Renthal bars. Gauge and bar end turn signals from Motogadget. Everything else done by yours truly.


A few intermediates:


-- Had to machine a bushing so the existing vacuum-operated petcock would fit the new (old) tank. Works beautifully. NH threads are M20x1...yikes.


Fitting this tank was a nightmare... but worth it.


Still gotta get the electronics pan powder-coated, but that's about it. Droopy fuel line on this iteration because I was taking the tank on and off constantly for fitment. Nothing like flexibility.

YES, I got pods to work just fine.

Hoping to sell some of the intact stock parts. Original seat is pristine. All the exterior plastic is fine, (somehow) as is the airbox, rear fender, both mirrors, etc. Tank and exhaust are both up for grabs, but took some road rash. Let me know if there's any interest.

The brat looks great.  CB 750 tank is a great choice.  What exhaust do you have?  The NH lends itself to many different styles.  I prefer mine stock, but I appreciate a fine custom conversion.  Have you recovered from your injuries caused by cager?  We had many riders sharing their riding experiences on the old NHF,  but very few do so now.  Would be a good learning experience for others.  Enjoy riding the brat.

Thanks, Hog. Exhaust is a MAC unit. Needed a lot of coaxing to fit the engine, but once I got it on it's been lovely. I'm all healed up! thankfully still young and bulletproof.

Looks great.
Just a suggestion.The dual light you got looks "cool" but impractical as far as night riding and safety.
I suggest get nicer bigger around one similar to Motto Guzzi

Very nice!
I agree that the headlight should be changed. It looks too cartoon/Nintendo for my liking.

How would the headlight be worse if it puts out correct or more illumination?

thanks for the feedback, guys.
Rubo, I haven't noticed a difference in regular illumination between the duals and the stock headlight, and the high beam is definitely superior. serious bulbs in there.
Fastrednighthawk, it's the original fender with about four inches cut off of the front.
Raven, i've been a nintendo fan for a long time. ;) i understand it's not for everyone, though.

hate to be the guy who bumps his own thread, but oh well. after months of seeing other people/shops do wild fork conversions, i thought to myself - pffffffft. i can do that.

so, here's a 2008 kawasaki zx-10r front end all bolted up to my 1991 nh750. full disclosure: i am terrible at remembering to document progress with photos.





from what i hear, i probably could've used aluminum, but i made the stem out of 4140 chromoly. i'm gonna stick with aluminum next time.



did my own upper triple, too. included a flush-mount for my motoscope tiny. (honestly, don't buy stuff from motogadget. it's an expensive addiction. i started with one gauge, now i'm at turn signals and keyless ignition, AND i'm sketching up replacing my entire wiring harness. germans, my dude. always with the quality kit.)



finished! it's a charm. gotta put my dang headlight back on somehow.

Awesome. How did you handle getting the pods to work?

Did you modify the right side of the frame for the seat?

do you still have the stock mirrors and front fender, side covers and the wrap around plastic?

hahaha - very nearly. rejet, 0.030 needle shims, cut the fuel screw limiters and fiddle. probably wouldn't win a drag race (even i'm not stubborn enough to argue with the fluid dynamics of CV carbs) but low-end power is better and my general in-town performance is honestly not perceptibly different from stock.

Did you modify the right side of the frame for the seat?

the whole seat frame is new from the spine back.

do you still have the stock mirrors and front fender, side covers and the wrap around plastic?

front fender is gone, but yes to everything else. i'll snap some pictures if you're interested. also have the airbox, stock seat in pristine condition, license bracket, rear fender.

So what did you do to the carbs to get the pods to work correctly?

Dude, I am in the process of putting the same tank on my Nighthawk. I am having problems getting it to fit exactly where I want though. I am thinking I'm gonna have to hammer a tunnel into the underside so that it doesn't just sit on top of the framerail. I also have to reweld the front tank pegs a bit lower, but may be able to use existing locations with them just cut halfway down. I have those Emgo pods and the Mac exhaust too, but the pods won't fit behind the frame and the exhaust fitment needs a little finnagling. Your bike looks awesome too! Nice front end conversion. That is awesome how you machined the triple and tube yourself. Much respect! Any advice you can kick my way would be appreciated.
