Stretch Dyno Pandemic Project

[Budasac]

I saw this bike for sale a few weeks ago and felt like I had to do some thing with it.
It wasn't what I was looking for, and a little more then I wanted to spend for a donor bike, but it sure does look cool. I just love the long lines of the frame and the way it sweeps down in the back.
Although the bike is comfortable to sit on, it sucks to pedal on anything other then perfectly flat roads.

Very comfy bike to sit on for sure.

Cool ride Bud.
Same story with the stretch cruiser I recently purchased.Super comfy on the flat. But there are too many inclines where I live, so from day one it was always destined to become an e-stretch. Unleash that stretch's full potential.

The biggest pain in the but on this thing is trying to place the motor. Due to the low swept lines of the frame in the back there is a very small window for the chain to pass through and align with the motor.
There's a lot of room up front but the motor needs to be mounted as low as possible. Unfortunately, the lower you go the more it interferes with the manual drive chain.

 

[Budasac]

I had to lengthen the chain by a few links and reroute it around the motor...

That a sweet ride by the way.
I love the front end and the fat rear tire.
I think my next build is going to be electric.
Can't really ride the 2-strokes in parks or anywhere there are crowds. Too noisy. What kind of range do you get with that?

 

[Budasac]

I thought I had the motor low enough for the chain to clear the frame but when it was pulled tight there was rub. I ended up cutting a small section out for the chain to pass through and welded a support in place. I tried to curve it to match what I cut out so it lines up with the fender later.

 

[Budasac]

Welded a chain tensioner in place to route the drive chain around the frame.

Nice job so far!!

Here's the first one i ever built about 10 years ago... https://motorbicycling.com/threads/chrome-venice-stretch.14623/#post-145228

Stock chain guard almost looks like it was made for this bike. Just needed a little trimming.

 

[Budasac]

Of course the stock exhaust doesn't fit at all to allow for a test ride ..
Made a new exhaust flange from some scrap metal.

Dyno is coming along nicely. Cool frame re-model to accommodate the chain line.
No idea of my BLUE BAMBOO e-stretch's range yet. Build is still ongoing.

 

[Budasac]

Everything is rough installed now except the exhaust. Just need to finish the pipe and start her up.

Thanks guys. This is my second build and, even though it's kind of a tricky frame, it's going a lot smoother then the first one.
Plus I'm having fun. I basically taught myself to weld on the first bike and I'm slowly getting better. I've always worked with wood (furniture and cabinet making) but I love customizing and fabricating things and being able to weld opens up a whole new world of projects for me.

 

[Budasac]

The exhaust is all welded up and installed.
I was going to run it on the left side just below the frame but the chain was in the way. Then I thought about mounting it underneath, centered on the frame just behind the cranks. In the end, I decided to stretch it out, just like the bike, and run it all the way to the rear wheel on the right side.

I was able to start it up a go for a quick test drive but it was getting dark so I only went a few blocks.
Gonna put some miles on it tomorrow to break it in. Just a bunch of short rides to the park and back with some breaks in between to allow it to cool down.

Clean - and quick - build. Having fun with a build is what matters most. Plenty don't!
Just a suggestion... after you touch-in the welded areas on the Dyno's black frame, maintain the blacked-out frame/motor look by giving the exhaust pipe a sprayed coat of heat resistant black paint. This will fool the eye into giving the bike a more slammed look.
Are you planning on upgrading to an in-frame tank at some point? There are such custom-fit tanks available for the Dyno frame. Or, put your rapidly improving welding skills to good use and fab one.

Pete,
That was the plan for the exhaust. (I almost pulled it off and painted it last night at 11:00). As far as the tank goes, the stock one is just temporary. I wasn't aware someone made a tank for this frame. I was going to attempt to fabricate one myself but depending on the price it may be worth it to just buy one.

 

[Budasac]

So I pulled the exhaust off first thing this morning and cleaned and painted it.
After breakfast I wrapped it and installed it.
Pretty much exactly the same as my other bike but I left the muffler chrome.

Exhaust treatment works so well.
Nice stablemates!
