Tubing Joint - has anyone seen this in action?

I've fantasized about being able to unbolt a tube on the Max frame to gain quick access to a component - like installing the xj550 Airbox.

Someone has devised just such a connecting joint for round tubing:

Question is; Has anyone seen it installed, in use?
Does anyone know where such a critter "the part" might be obtained?

 

Your link wants a login and I have to install an airbox in a 550 too.

 

Its easy to register ... and well worth it to see the detailed drawings.

Keep in mind this design is patented.

Holy S***!! The patent drawings jarred my memory. It's been done. There was a Honda or some other mainstream late '80s - early '90s bike that had a removable section of the front downtube for some normal maintenance function but I cannot remember what it was or what bike. Google here I come.

 

On my yamaha vstar 1100 the right downtube on the frame was removable and the joints looked just like that. It came off so the engine could be removed from the bike.

However I think it is a silly and foolish idea to compromise the structural integrity of the frame in an effort to save what, 2 hours worth of work? Go ahead and pull the engine out, it is so easy a monkey could do it in its sleep.

You will end up spending much more time and energy trying to fabricate a removable piece than you would spend if you quit trying to cut corners and just pulled the mill. What happens when you screw up? You have to find a replacement frame. And guess what? The engine wont magically transfer itself to its new resting place.

 

All XJ700's models have a removable frame section (upper and lower sidebars, to boot!) on the right side.......

 

yep, ahahaha, muwahahahahaha! yes, yes i can remove my engine at any whim! haha, you all will perril in your engine removal!, now if i could only get 2nd gear to work...

 

You can Schooter you can. Just pull that mill (since it's so easy) flip it over and split the cases. Have it fixed in no time. Reassembly is the reverse of disassembly (don't you love it when the book says that and it LIED?)

I was thinking you'd probably have to pull the motor to be cutting/welding on the frame. Probably easier to just do that and make your fix. It's not like the airbox has to come in and out once it's in it's done (unless it self-destructs like mine is doing.)

 

My Magna has a removable section as well... It also doubles as a coolant tube.

 

so does a Suzuki GS500E

 

I wouldn't cut a perfectly good frame, unless it was completely apart, blasted, and was going to build something awesome.

 

My Interceptor had a removable frame rail as well. This is a fairly straight forward affair, just takes someone who knows how to weld and a sawz-all.

:lol: OMG bigfitz52 that should be in quotes in your signature

 

My dads 79 cb750 has the removeable frame piece in the right down tube I believe
