How to ruin a perfectly good stock frame

[almarconi]

I kind of like it...can't wait to see what the final product looks like.

ok if the calcualtion of the loads on the original config were ok.
WTF makes you thin making a longer , spindlier extension is going to be strong enough to suppport you and the engine?

I took this post as a joke.
I had no idea you would be making on of yourself by underenginnering an elongation, and thus, overstressing of a fine suzuki frame.

[mlc216]

You are right. I'll just put it back together in it's original configuration.

Enough with the sarcasm already, you're embarrassing yourself.

[mlc216]

I'm not embarrassed of anything. I just figured I would show you what I was working on. I don't give a crap what you think or say about how it strong it is.

I never said the stock frame was weak, it's just built for a different purpose. It IS stiffer than the frame I'm building, but stiffness isn't what you want out of a rigid frame. Will my frame handle like a stock frame? NO. But I'll never ask it too. I wont be diving into corners like a sport bike. Will it handle dirt jumping? I don't know, but I'm not going to try it.

I don't want to argue about the strength of the frame anymore... If this kind of project isn't welcome on this site then please tell me and I'll delete my posts and go ride my bike.

If anyone has any real questions about the design or fabrication of the frame, then I'll do my best to answer them.

Here's a question, you say you are an engineer, let's see the math. Looks like a death trap to me. This from one who has had a serious crash from a frame failure, the whole steering head popped off the front of my first bicycle. That bicycle frame was more stout than this one.

I'm curious if you are going to add any more steering head reinforcement or is this the finished product from a structure standpoint?

[chuck hahn]

hence my earlier question about adding gussets at critical weld joints!!

Chuck, that frame needs more than a few gussets before it's going to be safe.

Whoa guys...I love this forum, but EVERYONE on here is anti-custom it seems. I've seen this sort of flaming in multiple threads.

Anyways, OP please continue to post pics. I love seeing what an individuals thoughts on what a GS "can be" turn out to be,

[tkent02]

No one is anti anything, just hate to see people getting hurt on stupid designs.

[chuck hahn]

IM not bashing the dude. I just simply see the need at a few places as a minimum. he can build a 4 cylinder shaft driven outhouse if he so chooses..no skin off my nose.

If you want numbers I'll give you some in the morning when I get to work. Just curious as to what kinda bike it was? I used to race mountain bikes and manage a bike shop in college.

The neck doesn't need anymore reinforcement. It already has a larger weld group area than the stock neck. The main benefit of this type of neck design is that it eliminates any bending moment on the neck caused by the frame. You may not be able to see it in the pics, but the gusset on the neck is I-beam shaped which helps a lot with torsional forces experienced when cornering.

hence my earlier question about adding gussets at critical weld joints!!

I will add gussets in certain areas. Which areas are you inquiring about?

[chuck hahn]

Under the steering head and where the two lowers join in would be my choice areas...
