Re: Crazy Custom Frame Hobbit

The rest of the bike seems fine , but , the square tank and tail piece ...

I know , nobody asked me , so that's all I'll say . (edited)

I don't disagree - this is just a first draft for the tank/seat. I don't have the skills to build something rounded and the square stuff is cheap/easy.

I like cheap and easy . Just hope it doesn't ever hurt you . ;)

Curves don't really take that much more time .

First builds are first builds. Always problematic for everyone

And I think he has done a fabulous job. Managed to build a whole bike around one of these old engines. And it rides. Damn better than I have ever done. Kudos to you sir.

I always think of that scene in the Matrix where theyre like EWTF he's supposed to be the chosen one "everybody falls their first time"

lololol love it! Yeah, there's things I'd do differently, but I'm suuuuuper happy with it and it's beautiful. Main thing is going to be dampening those vibrations and some day shortening the frame a bit, but otherwise it's just spectacular. It's an absolute blast to ride, and it rips.

Also I've set up the rear seat cowl to be able to flip open and closed, so I can keep treasure under there.

Re: Crazy Custom Frame Hobbit

I constantly attempt to refine machines, that’s what I do.

Failures or accidentally making things non optimal for ones uses is the way she goes.

Then ya go back and redo, and redo, and redo.

That’s the way to become a fucking winner

Re: Crazy Custom Frame Hobbit

A lot of vibration is probably coming from the tank, and that'll resonate throughout the bike. If you press your knees into the tank while you ride and the vibration dampens, that's you know it's your main problem.

Dense padding underneath helps, or spraying the bottom with Plasti-dip spray paint.

Exhaust pipes are a vibration factor, too.

Same test, basically. Put your foot on it while riding, and see if it gets better.

I've used urethane skateboard bushings on the mounting bolts to help that.

Basically, anything that can rattle will cause resonance you'll feel through the whole bike. Gotta figure out each thing and isolate it.

Re: Crazy Custom Frame Hobbit

When I rigid attached my tank it was shitty. Extra loud and vibratey.

I used shop flooring strips under hose clamps and it was just what I needed.

Oh dank that's crazy! Super good to know. I would have assumed it'd just come from the engine being hard mounted!

Considering the challenge of getting actual engine mount bushings in there, I'm leaning towards just spacing it out with some rubber washers

Re: Crazy Custom Frame Hobbit

You have both problems tho.

You should fix the engine mount isolation for sure
