My second attempt at making my first seat was a bit more successful. But I’m not satisfied yet…
The shop has been done for about 8 months now and the concrete floor has seen many bikes, quads, and maybe even a car soon?! It is nothing fancy, but I will be starting my next shop build soon on a half acre I recently started clearing out. Now that will be fun! Some shop photos attached below.
Here is what it took for me to make the foam part of the seat.
I painted the seat pan:
Then I cut and shaped the 1″ firm foam for a base layer. Notice in the center I cut a “v” in the foam and glued it together so it would make the sharp curve and hold in place.
Once that layer cured, I glued a second, softer 1″ layer on top of that, for comfort and to make the seat the desired height. It took lots of delicate angle grinding and shaping to get it just right.
At this point I haven’t decided if I’ll do a fluff layer on top for the pleats. I may just glue strips to the underside of the upholstery and see how that works…but we’ll see.
Rough fit on the bike, just to get an idea. And below you can see the tail light I also installed last night.
Now it’s really taking shape! I have on order 20 new main jets so I can tune the carbs perfectly. Stock main is a #102, I ordered sets of #105, #110, #115, #120, and #140. I’m pretty sure #120 will be the right one but every bike is different. When they come in we’ll see if she runs!
I’m going to my mom’s now to start upholstery.
So I finished wiring the bike awhile ago but forgot to even check for spark! Or maybe I was subconsciously afraid of what I might find. Sure enough when I turned it over with the plugs out there was nothing. All new NGK D8EA plugs, tried it with four different coils, and two sets of TCI units. So after all that I pretty much have it narrowed down to the pulser, which is not much of a surprise. That’s probably the reason the bike got parked for so many years before I found it anyway.
So here is the culprit! I adjusted the gap on them and was able to get very intermittent spark from one coil…So I’m pretty sure these bad boys need to be replaced. Luckily I have a parts bike in the yard (Arkansas style!) so I don’t have to spend another $100 for this unforeseen set back.
On a brighter note I got my starter button in the mail today and immediately set it up, it’s nice and subtle.
Works great! Once I mount the tail light the wiring will be 100% complete. Oh and replace the silly little pulser…
I finally sat down and finished the wiring, it took me about two hours to do since it was my first time to wire an electronic ignition CB750. I have done a few viragos with EI systems and I can do them pretty quick now. The CB750 was more complicated because it has two separate TCI units. Here is the simplified diagram that I found and used. Gotta love the internets!
I know it looks like a lot of wires but it is really pretty compact since that’s all the wires on the bike, that will all be under the gas tank of course.
I just used one main fuse between the battery and key switch. The master cylinder I installed has a brake light switch built in, so I wired that into the harness so the front brake will trip the brake light instead of the rear. In the past I usually just use the rear switch but it doesn’t look as clean and generally riders use their front brakes more than the rear so it is a bit safer this way.
If you look close you can see that my ground-to-frame is about 2″ long which is awesome 🙂
On an unrelated note, I was walking to go get the mail and as I passed my girlfriend’s parked car something bright white caught my eye below the steering wheel. Upon closer inspection I found this!
Here i’m staying up all night wiring motorcycles and Jazzy is just snoozing in the car! What an easy life.
So I have all these wires I’m trying to hide, I want this bike to be as clean as possible and the bikes I’ve seen like this one have NO visible wires! So I started thinking…
first, place battery (new gel CBR600 battery). This is where it is going, I’ll make a bracket for it soon. Wondering why I welded those pieces of grid metal to the frame? Now you know! to hide the battery…and it looks kinda badass.
Next I had to figure out where the hell my pulse generator and starter wires were going to go. I didn’t like the stock path on top of the motor and scaling the frame in broad daylight…
So I found an alternate route behind the front sprocket cover and down underneath the bike, coming up the back of the motor right in front of the swing-arm. Of course in order to do this I had to stretch the wires quite a bit.
SOLDER AND HEAT SHRINK are the only way to go! I will say this till I’m blue in the face.
Who’s idea was it to put a brown recluse on my knee and tickle me until I swatted it to the floor…only to realize it’s a…BROWN FREAKING RECLUSE! Try to get this picture as big as possible, click on it, zoom in, whatever. If you look close you can see the little violin on his back…bastard.
So now that I’ve beaten the spider, and finished the soldering…see any wires? GOOD! you shouldn’t! (hint: note zip-ties on each side of kick stand…)
Here is the hidden goods. There is a total of 10 wires there, nice and compact. That’s the majority of the bike’s wires right there! stator, starter, and pulse generator all come up there together now
That’s it for tonight It’s 2:30am and I still need to shower! But stay tuned because tomorrow I plan on making my battery bracket and getting the wiring at least mostly complete. Good night.
So I changed my plans yet again on the gas tank…I ended up going back to the original tank after all that humming and hawing. Kevin took it yesterday for paint. He is going to mix dark blue with gold to make a deep metallic green. It sounds amazing and I hope it turns out well! I won’t see it for at least 2 weeks, which is fine because that will give me time to do the wiring.
Here is the gas tank that is being painted right now…sweet flames!
Today the CB750 rolled on its own! I finally got the CORRECT chain and sprockets so I was able to put the rear wheel together and mount it for good. I also loaded the front forks with 8oz of fork oil (4oz 10W and 4oz 15W) and finished bolting the front wheel on. Got a speedo hooked up and she’s really coming together!
Well…still might look kinda bare…
check back soon! I’m going to be building the battery box and wiring next, as well as the seat pan.
