Cobra Cafe Build
« on: Jul 22, 2015, 18:17:25 »
Folks,

Just finished a 18 month build with my son. Would love some feedback...I chose to use a little used engine on the "A" as I wanted something different and got a great deal on ebay for $50! with a different cam and bigger carbs and jest it is surprisingly quick.

Here are the build specs...

1978 cb750a motor (from a wrecked bike - some rebuild necessary)
1975 CB750K cam shaft (better compression ratio)
1981 GS1100 32mm Mikuni Carbs (total rebuild)
40 pilot and 140 main jets
Oval Pods from Alpha Motor
Custom carb boots - made from 1.5" marine exhaust hose
Tank - 1981 CB750C2 (stripped, filled dents and painted)
Rear Seat Section (fabricated from fiberglass)
Custom Seat - (built myself - has 3/8 gel pad - assembled leather work on my Grandmothers old Singer Machine)
Jockey Shifter - Flame cut steel from company in Wisconsin
Wheels from 1978 KZ650C2 (7 spoke mag wheels - 17" rear 18" front)
Triple Tree and swingarm 1978 KZ 650C2
Neck Bearing kit - All Balls Racing
Wheel bearings - All Balls Racing
Steel Brake Lines front and rear
Front Brakes - 2003 Suzuki GSXR 600 - built custom mounting brackets
Rear Brake - 2005 Suzuki GSXR 750 - built custom mounting brackets
Handlebar - Royal Enfield
Front Fender 1977 KZ400
Rear Fender 1979 KZ650 (front fender cut to size)
Wiring harness - all new...I built my own
Head Light Housing - 1977 KZ650
Head Light - 7" Harley Headlight
Bulb - 3000lm LED Bulb
Brake Light/License Tag - 1928 Model A repro - white LED lights for tag
recessed 12" LED strip light for additional brake light
13.5" gas shocks
5/16 rear sprocket spacer bracket
15 tooth front and 46 tooth rear sprocket
530 chain (from my old Hayabusa!)
Dyna Tec Ignition system
Iridium plugs
Exhaust is a Voodoo pipe I chopped and welded a hotrod exhaust connector on
Paint - Electric Blue Pearl and Nordic White - Enamel Clear coat.

I ended up having to fabricate a lot of small things as Suzuki, Honda and Kawasaki were never really meant to go together!  My son and I did the entire build without outside help. I wanted to use it as a learning experience for him and a fun Father/Son Project. He is 12 and we are planning to start building His Bike next.

Hey!.  That's a good looking machine!   Nicely done different with the automatic too.  Your jockey shift is .. creative.    How does that work with a left hand clutch ?

Thanks! Since the motor is an "A" model it is clutchless...so what is traditionally the clutch is actually the rear brake. The torque converter is on the oppoaite aide of the motor. Makes it kinda fun as it means no foot controls are needed. However when you shift into low it kicks slightly when you engage so a firm grip on the front brake lever is necessary...or you get an unexpected jump!

What is your opinion on the rear shocks ? I have heard many people think they are junk, I've been looking at a pair for my KZ650-C2. I love the look of the piggyback shocks an at the cost of those, I think I'll take a gamble on them. You did a very nice build on the cafe..... I like it... Wayne

I really like the shocks. They run about $100.00 and for the money it is a good deal. They are also very flexible and provide both a mechanical and gas option to adjust travel and tention. I took some time to find shocks that fit my need...I am 210lbs and these work well for me. There are definitely better options out there, but they will run you more money. So the choice every guy faces is performance vs. value! Good luck.
