That wouldn't really fit with what I'm trying to do for the rest of the bike, but thinking about it, I really like that idea, I will probably do that on my next bike I build.

Hooray for Parts!!!!









Here you can see, I got my air cylinders, air compressor (it's the 3/4hp model, I wanted the 1/3hp which is smaller, but they were backordered for 6 weeks, and they gave me an 80.00 discount to upgrade), 1 gallon air tank, air valve, rear sprocket, headlight, jackshaft assembly (minus the sprockets, they'll be here next week), rear axle and wheel spacers (they need to be cut to fit), and the chain (which was a nice suprise, because the color scheme on this bike is going to be satin black and gold, I didn't know the chain would come gold like that.)

Here's a somewhat mockup showing the placement of stuff in the rear section. This stuff is by no means set in stone- it's all dependant on how it goes together.



And a fun shot of the headlamp mounting position, I really like this headlight, little bit of old school look to it.



I have to go to Seattle all next week for training at work, then another week of work, but then, over christmas and new years time, I get that whole week off, and much should get done. I'm renting a plasma cutter to cut brackets and mounting tabs, ect....
Here's my to-do list:

Finish bars with headlight mounting point
Install compressor, tank, and cylinders
cut out seat pan, basically finish the seat besides covering
cut out license plate backer plate and finish mounting to side of swingarm
Finish rear axle blocks and get rear axle mounted in place properly
Install rear sprocket and set up jackshaft assembly
Attempt to pressurize system and see just how much clearance I have

I also need to put the motor back in during the air system install, to make sure I won't have any clearance issues later.

Thanks

wow, i thought that's where the transmission went.

96turboracer

If it were a Harley then yea, but with the little jap motors, the trans is integrated with the engine itself. It's all one self contained unit.

Got the headlamp mount made today, don't mind the mess, I'm gearing up for the last week of Dec. should get a bunch done:





This shot is kind of funny, looks like the light is on because of the flash



here's a closer shot



I kind of tried to match the curvature of the headlight with the mount, and I'm pretty happy with it. Final welding and blending has not been done on the mount or the bars obviously.

the headlight mount is going to vibrate, add some bracing

96turboracer

'Tis in the works captain, from what I hear, these motors vibrate almost as much as a big twin!

Sorry I haven't updated in awhile, I didn't get as much done as I wanted to in my time off, I think I kind of forced it too much, and in the process I made something I didn't like. I almost went ahead anyway, but I just couldn't look at it and be happy, so I took it off.

What I did get done:
cut out the seat pan:



Finished up the rear axle blocks, so the rear wheel sits in place properly now (also mounted the sprocket), you can also see the baseplate for the rear section that I cut out, haven't finished it though:



In that last picture you can also see the bracket I made to connect the air cylinders to the swingarm, they turned out OK, but then I was trying to make the mid-bracket, the strong one to hold the cylinders in place, like so:




It turned out so-so, and the longer I looked at it the more I hated it, so out it came. I'm trying to think of a better way to mount it right now.

I also tossed in the motor to make sure that nothing I was making ended up in the way of anything else. Note- the exhaust will not route like that.

I also cut out the brackets to make the forward control for the shifter, that should be done this weekend (hopefully)

Now to one of the main issues. When mounting the cylinders, I was under the impression that the output sprocket on the motor was offset more to the side, with the motor in, here's my mistake:



Whoops!

I might have to run a dual jackshaft type deal to get it to clear, but I think I've got it figured out now.

It was just one of those things where I was putting too much pressure on myself to get stuff done, and it was taking the fun out of it. So I had to take a break for a couple weeks to get the passion back. After all, if I'm not having fun, then why am I doing this?

Anyway I appreciate all the support I've seen here, and now that I'm back on the wagon, I should start getting some regular updates again.

thanks

I've got a new idea as far as mounting the air cylinders, but to make the bracketry I'm getting a bandsaw in a week or so. So I decided to work on some other little things.

Worked on the forward control for the shifter:



But mainly worked on mounting the seat pan:

I think I definitely went overkill on the thickness of this stuff, bending it was a pain in the ***!



As if that wasn't going to be enough, bent up additional support for the bottom:



Drilled the base plate peice and the pan itself:







Turned out pretty good I thought. Still have to do finish welding on it, it's just tacked into place right now. But I'm happy. Maybe tomorrow I'll work on mounting the license plate mount.

impressive progress. why not run a single air cylinder in the rear?

96turboracer

There were two reasons, First, the added stability of two attachment points on the rear swingarm, and more importantly, because I'm expecting this thing to ride like a rigid when aired up, the force the cylinders exert must be strong enough to overcome any force given to them while riding. I got a table chart that showed sizing, and to get the same amount of force I have now with these two cylinders using only one, the cylinder would be about 5" bore. Which I think would look pretty silly, and it would be pretty expensive.
