Saving a 1980 750 twin.

I’m takin this bike on a road trip this summer so I fabricated a luggage rack, crash guards, and a better kickstand. Also got it running. The video really kill’s the sound. Makes it sound a bit “ farty”.

Sadly this will have to sit for 2 months until I’ll be able to ride it. I accepted an amazing job in LA so This will be in storage for a bit while I move. The bitter sweet part is I will loose access to all the cool tools I have had at my disposal. I have been working 1 or 2 days a month at my old college to retain access to their shops. That’s all going to stop now

She will make a good mountain bike.
Cool parts Doc, are they stainless? I couldn't get the vid up?
Congrats on the new job good luck!

Of all the cool parts of this build, I think the timing cover is my favorite detail. I just went back through the whole thread to try to find where you got it, and it turns out you both designed it and CAST! it yourself. That's crazy cool.

I recently found a vintage patch of the flag with the river symbol, and I'd like to put this onto a project at some point. Any chance you'd be willing to share your CAD model with me?

Not sure why the video didnt work last time. I entered the URL again and seems to be working now.

The rack is just regular mild steel, the crash guards and kickstand are chromoly. I'm going to polish the butt welds back on the crash-guards so they are seamless and then everything will get powder coated.

Thanks man. PM your email address and I'll send it over.

New petcock came in and I had a little time while moving to install it and go for a ride! It just barely clears the cables but clearance is clearance. I only rode around for 20 minutes and first impressions are; needs taller gearing. This thing rips to redline way too easy now, noticeably smoother with the crank balanced as well. I didn’t have the balls to go WOT yet but at half throttle bursts I was impressed by the power. The new race tech goodies in the forks have transformed the front end as well. It was diving pretty bad before and that is completely gone, it also feels more stable as well. The new brake setup seems adequate but because the pads are still bedding in I didn’t reef on em too hard. Overall good improvements all around, however is has brought a handful of small things to light that I will need to address, like a shorter turn throttle. Can’t wait I get this bike on the dyno to see what kind of power it’s making.

Sounds healthy!

Almost sounds like a big four. :woohoo:

Wow I love everything about this build. I can sympathize with loosing all the cool tools. I relocated as well and lost many cool toys for building , I have a feeling as nice as you build you will find a way . Any ways great build .

This summer has been crazy busy and full of highs and unfortunately lows. Ill start with the good.

I got the carbs pretty dialed in on this bike. It pulls hard! I was never totally happy with the seat I made, it ended up being more round in shape and my stitching was amateur hour, plus with the increase in horsepower I wanted more butt cup-age. I found a guy down here in LA that made me a killer seat while I waited. If you're in the greater Los Angeles area I highly recommend JP's custom seats. super nice guy and very reasonable prices. The work speaks for its self.

I short shifted and hit a false neutral, resulting in over revving the engine (D'oh!)The stock length shifter is just way too long, so I remade it again with a new toe peg as well. I added some bolt on braces for the luggage rack, and I also made some grab handles for when i don't have the rack on. Everything got powder coated in a super-durable textured black to contrast the frame. I didn't have much stuff to meet their minimum so i coated a bunch of other stuff as well like the top triple clamp.

a couple small things here and there like new grips to match the seat, and a quick turn throttle for maximum fun action.

Here are a some hero shots of the bike. Ill post more soon.

couple more

Very nice.

Sweeeeeeeet!
