Title: Darkness 78 CB750
Post by: Hutch08 on Mar 08, 2016, 19:56:47
Hello everyone, first timer here. Been a follower of DTT for the past year and have to admit I got the fever now. Cafe fever. Never was into motorcycles before but have always wanted a mechanical/paint project. Figured why not learn and have fun with everything on a bike project. I wasn't sure of what bike to start with but was drawn to the CB series and only want to do this once and the right way so I opted for the 750. I found one luckily close by and at the price range I had available. Picked her up about a month ago and she starts and rides fine which is a great start.

DohcBikes, the fender was removed by the previous owner along with alot of the stock parts. It looks like he tried to start a build but didnt have the space to do it. The pipes were also wrapped by him and it was the first piece to go. Actually had to remove the pipes to roll the bike into the truck for transport on the purchase day. The wiring was tagged/documented for future information or reference, the harness is off the bike right now and hope to do a new custom harness. The seat and clubman bars are for sale as they are not going back on

The theme or inspiration is the Clockwork 22 750. I fell in love with this bike and is the reason I was strict on looking for a 78. A lot of people don't like the tank on them but I like it's unique style and the sleek fuel door look

Mocked up the rear hoop today. There are sleeves added inside for strength. The suspension mounts will get re-enforced later. Also mocked up an electrics tray and side shields out of cardboard in case they need modifications as the build progresses. I am relocating the oil tank behind the air filter so that's next to come

I'm digging it man, that tank filler worked great.  Inspiration bike looks amazing too, looks like it even has tire clearance built into the seat.  Just about perfect in my book, though I do prefer fenders to none.

Oil tank arrived yesterday from CognitoMoto and installed it last night. This tank is awesome, very heavy duty and is well made. I did have to remove two more tabs that interfered with the top of the new tank where the old tank had its mounts. The hoses were a bit of a challenge but some heat and grease helped. I am not going to keep the rubber frame fasteners but instead weld some metal tabs for a clean flush look

So I've been at a standstill for a few weeks waiting on parts. Been researching the GSXR fork swap topics to find where to start but have no idea what year or model fork fits best for the stock 750 characteristics . Hanes manual says 484 free length for the cb but GSXR is in the 700's thinking that can't be right. I'm going to replace the hub, axle, and triple so just need fork length for rake and trail. Asking for some help in being pointed in the right direction on lengths
Title: Re: Darkness 78 CB750
Post by: slikwilli420 on May 26, 2016, 17:29:32
Fork length isnt as much of an issue as getting the geometry right. When doing this swap, the GSXR offset is way too small for good stability on these bikes. Lots of guys go for stock CB offset with the proper spread for the GSXR components. That helps get back to more sensible trail numbers. I would be happy to help with a set of custom trees. I have a number of designs available and am my offering is very competitively priced.
Title: Re: Darkness 78 CB750
Post by: Hutch08 on May 26, 2016, 18:41:58
That's what I'm looking for is close to stock trail and rake. I figured length is all I needed to figure out because I don't want to change offset of the stem. To long its like a chopper, to short it can't handle corners. Trying to find that sweet spot, and there are a lot of sizes for GSXR forks. The bike I'm referencing used 1000 forks but seems like a lot for this CB

How have you managed to insert the right Brook grip into the throttle tube.

The throttle tube should be around 24.5mm or 25mm.

Ok gents, after a month or so I put the wheel back together. Had the rim and custom hub powder coated and used new SS spokes as I didn't want to redo anything in the future. This was my first time for everything including removing and installing the tire/tube, and lacing a wheel. The lacing and truing was tedious but got it locked in straight. Ran into a problem today when I tried to install the calipers. The rotors are in the middle where they should be but is now hitting the spokes. Any ideas on what is causing this? I thought maybe I had the forks backwards but the air dampen knob for the forks should face outward right? Need some input please

My good friend Anthony helped with figuring out the front wheel problem. I laced it wrong because of the new gsxr hub and tried to replicate the OE wheel pattern. Took it all apart and relaced the wheel and calipers fit perfect now. The next step was welding the frame hoop together finally so I could start making my seat. I also welded the rear set mounts so linkages are in the future

That rear brake is not gonna work, the pivot point is way too far back from the swing arm axle you need to raise it and pull the shocks so you can move the swing arm up and down to see what I'm talking about... also, good luck finding neutral.

Run your linkage forward to the stock brake shaft. It'll allow you to run the stock light switch, and return spring, and you won't have your brake dragging everytime you hit a bump.

On the shift side, figure out how to run a straight rod. Kinked rod is going to flex.

So I found "the" set of what I wanted to buy from extremecreations.com but a $350 price tag was not feasible. Baught an aluminum block from Amazon with 6ea $7 micro switches and milled them out on a friend's machine.Made a template out of wood with the holes drilled and copied it once it fit correct. No pics on the process of it, didn't think of it at the time

Received the new 4-2 exhaust from cycle x and it is awesome. Next to make the left side hangar. Carbs are all torn apart and cleaned, just polishing the top hats and float bowls till I can get the rebuild kits(https://uploads.tapatalk-cdn.com/20180104/4c99a8fe6c912ea1ccd90c3fa2a34469.jpg)(https://uploads.tapatalk-cdn.com/20180104/826d0e7f1095cddfc64bb666c184e6ca.jpg)
