1979 CB650 Brat. -New photos

Here's my latest build -'79 CB650 (tank is off an '81) Bought two years ago not running, ended up just being a matter of cleaning the carbs out properly and fired right up. After that I Stripped the bike and altered the frame a bit to accept the new tank and eBay seat, made sure I could tuck most of the electronics out of the way, built a battery box, painted pretty much everything that could be painted, rebuilt/rejetted the carbs and added the stacks, as well as rebuilt the forks, lowered them 1.5" and added knock off emulators. This winter I plan on adding 14" ikon rear shocks, GM HEI ignition conversion and a clutch that hopefully won't slip as well as tires that will stick to the road a little better. Thanks for looking. (Sorry the pics aren't in any sort of order. I'm horrible at build threads)

Wow....That thing is a beauty! Really impressive work.  Couple of questions, is that a generic chinese ebay seat?  How did you get your carbs so clean?

Thanks man! It is a generic eBay seat. This winter I will probably stuff a gel pad in there and add a small amount of padding as well as get it re-upholstered with higher quality materials but for now it's better than a plank of wood. I had the carbs ultrasonic cleaned, but I also painted them before reassembling.

Where are you getting parts from?  I am on a 650 build but missing one new piston.

So far I haven't had to dig into the engine, luckily as it sat for 14 years. But between dime city, siriusconinc and my local Honda dealership (Valve seals and misc engine seals have been surprisingly cheap there) is where I've gotten everything. If I end up tearing the engine apart it will be getting a dynoman "big" bore kit.

That is beautiful, great work! Love the tank paint and the seat color, did you paint the tank?

Thank you, I did all the paint and metal work myself, except bending the rear hoop as I don't have a tubing bender (or place to put one) yet

What exhaust are you running? I'd like to get a 4 to1 similar to yours

It's a MAC 4-1 that came on the bike when I bought it, and I altered it slightly.

Here's version 2.0. This winter after testing compression and getting 60psi on 2 cylinders I decided to rebuild the engine and make some other improvements, it got:

Dynoman 10.5:1 cr 674 big bore kit, mike rieck stage 2 ported head with 550 valvetrain/kibblewhite springs (so I can throw a monster cb550 cam/hardweld rockers in this winter) gm hei ignition modules powering dyna .5 ohm coils, motogadget m-unit, turn signals, hagon 2810 shocks, tires that stick to the road, cone engineering muffler and a better quality seat upholstered locally (made the pan myself from fiberglass) amongst other things
