[UPDATES ON LAST PAGE -- 09/05/10]

I just want to start off saying that like most people, I was very influenced by the current bikes coming out of Japan. Only fitting, too, that these bikes were made there. MANY people dig "Bratstyle" -- and I'm one of 'em. Not only them, but many of the NFK (No Future Krew) vintage Harleys, etc. I just love the Japanese take on motorcycles in general.

In my garage I had two bikes to work with and neither were the typical bike for this style. I wasn't feeling the B.S. DOHC 750 on the website because it was that weird mix of Cafe and Bobber. I think it works on some bikes and blows chunks on others. Just didn't look like much was done to the thing to be honest. Can I achieve the look of those B.S. Yamahas and Harleys with an SOHC 750? The engine is so big! That was the first thing running through my head.

I'm working with a local guy who's been doing bad-ass XS650 customs (Joel at Solo Cycles here in SoCal: joeler86@yahoo.com) and he's knocked the frame modifications out of the park. An X650 that Leadfist Cycles built was our schematic for achieving the "correct" looking seat portion with the curved rails and seat.

Got it for $400.00. The guy riding it was about 70 and had a hook where his left hand used to be. He had to ride it down this winding steep ass hill.. standing up!

Don't need one with the Auto! Has a deeper oil pan and a nice little portion of it hides in the extra space of the Torque Converter.

Good work! Man... this is so similar to where I am right now with my z750 - the frame works I mean... Wanker of a frame and none to subtle engine. More of a challenge = more satisfaction! Keep it up WarGhost. Looking forward to seeing this one.

I love the high-shouldered front rim. I'm having it powdercoated and re-spoked right now. It'll receive a 19 classic Firestone. The rear wheel, which is 17, is becoming a new 16. Still lots to do! The tank is going to need bodywork and a nice paint job. I'm also chucking that rear fender for a ribbed Triumph one. I got some more rad shit planned for this bike. Hoping to get it done in time to ride it to the Hippy Killer Hoedown. Stay tuned!

Looking good so far. I've got three matics laying in the shop waiting for a build day.
Soon....I promise.......soon. Just gotta finish a few of these other projects first. Two of them are cb750s and the other is a CBX inline Honda six cylinder.

Keep us posted. I've seen plenty of "Brat" style inline fours and they look great.

Yeah there is a thread on the Lowlife Build (cb750 not a matic though)

And I think there is a thread on the CBX as well somewhere here

I haven't started the new matic builds yet but have one in an Amen frame build already as well.

JP, what do you suggest in terms of Carburetors? Should I ditch the 'Matic carbs? I hear nothing but bad things about them. If I do, which year/model CB750 carbs do you recommend?

jpswino
02-10-2010, 11:16 AM
The matic you see there in the pic uses early cb750 carbs ('76 and older). The stock matic carbs have a vacume operated portion which allows the motor to have a lower idle while at a stand still. Just like an automatic car. These carbs are a bit less effective for performance so most guys ditch them in favor of the well liked early carbs which are easy to find and relatively cheap. The '77-'78 carbs with the proper boots will work just as well too. But these carbs are a tad more complex to jet/adjust/sync than the early ones. Make sure if you choose to run the later carbs that you have the matching boots as they have a different throat size. The '79 and later carbs off the dohc WILL NOT WORK as they have different spacing. And if you are lucky enough to have a set of very early 1 into 4 pull sandy carbs ('69-'70), I am sure they would work with the proper boots as well but those carbs are rare and expensive.

The flip side to this carb swap which is a bolt on modification with the correct rubber boots is that your idle will be slightly higher while at a running stop and in gear. SO most guys just run a front brake to hold the bike back so it does not creep. And thats all it will do. Its not like you'll be holding back a burn out or something of that order. You'll see the matic in my pic which was set up by a buddy of mine when he owned it is running a rear brake only. But the rear brake works off a hand lever so that the bike could be held back at stop lights.

So I suggest early carbs and boots with a front brake as the perfect scenario.
That is unless you feel up to the task of installing a sport bike fuel injection system and microsquirt processor. Now that is the real ticket! And yes its been done.

Good Luck!

Got a bad oil leak coming from the left case that I need to check out, the stupid petcock was leaking, too. Argh.. Need to install the choke cable, and put the new exhaust pipes on. Going to run some black Mac Drags that I bought from Cycle X for a while. From there, I'll need Joel to help make me a custom headlight mount and probably run some different bars in the future. It's coming along though! Can't wait to fucking ride it all ready.

How does that CBX do? I'm craving one, but I haven't seen any great deals out there. Can't even stand near one for less than 4 grand. Beautiful bike though

You gotta really really really get lucky or really really really want one.

But I'm here to tell you, 103 hp stock is what the book says.
That damn thing pulls like 200hp! and there is absolutely no limit on running it out.
It just keeps pulling.

Still under the knife and having to work out some details. I love this tank, so I handed it off to Joel (Solo Cycles) to see if he could patch it up and make it work. The color is like a burnt orange. I really dig it. Here were a few pics I took before the bike left the garage:

That is an awesome tank. It will look great. But you might need a 2nd tank to hold the gas in. What is that about 2 gallons? I have a cool one too and the tunnel is so deep it cuts the capacity in 1/2 at least. You should frisco that tank, it would set it off really well and you'll get some extra miles out of it.... sorry that was the practical me...

Love the build so far!! Im thinkin about runnin the same rear tire. Looks real good on there. Nice stance on the bike

WarGhost
03-18-2010, 7:10 PM
Thanks guys.

Yeah, the tank is definitely getting the Frisco treatment, especially because of the low fuel capacity. Hopefully it'll work. The inside was rusted out real bad, and the rust even chewed through the tank and left a few tiny holes.

Viz, I love that rear tire. Some of my favorite Brat bikes ran it with black rims and that's pretty much what sold me.

Yeah, the black rim with the double whites is so bad ass. Im most likely runnin that combo on mine too. Its just classy lookin. Keep up the good work.

New exhaust (Black Mac Drags), bars I had done by Rock's Chops (narrow rabbit ears with about a 10 inch rise that kind of flair out) and a new tank coming soon. Just bought a set of completely refurbished CB750 carbs (ditching the 'Matic ones) so getting it running right is the main objective, then it'll get some more love in the cosmetic department.

05-19-2010, 1:29 AM
Thanks guys, it's finally coming together. After having installed the new bars, I really want to get a little "V" crossbar welded kind of low connecting in the middle. I think they'd look a lot better this way.

Carbs were bought on eBay. I just got them in the mail and am completely amazed. They glow! Best looking set of 750 carbs I've laid eyes on.

The headlight retained the original "arm" it was attached to. I think that's my favorite part of it. Usually you just see the bucket attached to a bracket. The bucket itself is aged perfect in my opinion. No matter what I end up doing in terms of how clean this bike gets, I'll leave that alone.

get those carbs from a guy in winder, ga? he does amazing rebuilds and puts them up on ebay. ultrasonic cleaned and all. but depending on how much you paid for m, you could sell them and for a little more could get the cycle x kit which will scream....

WarGhost
09-04-2010, 11:55 PM
Thanks man! You know, for the life of me, I can't remember where the guy I bought these carbs from is located. His auction was very detailed and he offered the carbs in black or just polished and cleared (the ones I chose.) I was literally able to put them on the bike and go. I haven't had to re-jet or mess around with them at all.

Oh, and as far as the Cycle X carbs, I really thought about running those but a lot of guys over at the HondaChopper forums said they work best with an electronic ignition (something I haven't converted my bike to) and told me a lot of guys run these early K series carbs on their Matics for better performance, etc. I'm super happy with these.

As far as the foot clutch and what not -- no need! This is the Automatic version of the 750, so it's as simple as turning it on, putting it in the "high" gear, and giving it throttle. It's such a fun bike to ride and isn't some "slow" piece of crap. I ride the shit out of it, freeways and all.

I put a new tank on it today (Narrow Alien) that has some modifications I asked Joel of Solo Cycles to do, so new pics coming soon.

The bike you did for your bud was a huge inspiration to me. I think his bike captures the "Bratstyle" look probably better than most American versions of those bikes that I've seen, so my fabricator and I chose your direction in terms of the rails and seat. So like I said in my OP, props to Leadfist.

Hoping to get in contact with Blue Moon Kustoms for some graphics and paint, maybe Hardluck for some leather. Going to finish cleaning up and painting the frame a nice Satin Black, powdercoat the valve cover and exhaust flanges.. Might make some new pegs as well and slap on a DOHC swing arm for a bit of stretch and better looks.
