Reynolds 531 brazed together would be my choice, looks sexy too....

I saw how people are making brazed bicycle frames. That's pure art !

XR69 Suzuki frame...531 brazed..

Where what picture?

This one.


I LOVE the way you did the mono shock.  I haven't ruled out doing a mono shock on the 550 yet and I dig the way you integrated that connection into the frame there.

[SOHC4 Cafe Racer Fan]

Mick,
That frame always makes my jaw drop.

MM - What kind of shock did you source for the mono? Existing part from a sportbike?

[Retro Rocket]

Mick,

Don, I'll keep posting it until i can talk someone into making me one....

That's some custom vise or some old east Europien one. Not sure. It is my friends vise... Will ask him tomorrow

Shock is from R1 2011. It will be very uncomfortable  ride

I had a similar vise marked made in Moravia..
 Sold it when i moved the shop in Feb.. Wish I had kept it..

Give Paul Brody a call. Probably one of the best brazed frame builders around.
Major motogeak too. http://flashbackfab.com/excelsior-project-paul-brodie/

I actually know a guy here that builds frames but I haven't been game to ask him a price, everything is dear as poison here, I've spoken to Bakker in the Netherlands but I'm after a frame I can pass {at a distance} as stock and don't have to sell a kidney to buy....

[MessnerMoto]

Actually my friend who is doing metal works for me can make custom frame... But it would be tig welded.. But for less then 3k

[bwaller]

$3000 for a complete custom frame is short money boys.

Yep, Time to look into getting someone to bend some tubing and get it brazed here. Brent, do you have any idea of what type of steel is used for the rear engine mount section and foot peg mounts  brazed to the frame on Reynolds 531 frames..?

[SOHC4 Cafe Racer Fan]

Brent can vouch for Denis Curtis at CMR.  He does build TZ replica frames and Honda Drixton frames for different displacements.  I bet he could do one for a 750, but I think the 550 engine is better balanced for race/track applications.

You've seen the 750's racing here Don, no 550's any where near them....   The frame subject pops up from time to time, I'm always fishing for options...   Hijack over...

just personal taste that's all.

 Are you going to keep the rear shock turned with the reservoir facing forward? it looks like it will interfere with the Air filters with it like that?

It almost sounded like you said "air filters' just then.

:-)

[MessnerMoto]

What air filters? There is enough space for K&N filters or something similar... but probably it will go with velocity stacks. I will get better picture next time. Shock reservoir goes in 50mm compared to frame tubing....

 Well I would think he's not going to run Velocity stacks on the street?

[RAFster122s]

Godffrey, I have seen a few do that only to learn some filter sock isn't enough even if cleaned and ouuuiled. Then I have seen velocity stacks put in a airbox without knowing the basics about optimum design use with stacks requires a open unobstructed area beyond the stacks equal to the height to 1.5x the height as a minimum and the stacks lip design being critical to performance within that box. The inexpensive sheet metal stacks do not have sufficient material at the opening to be used inside filter box. I have studied the flow dynamics for stack design and configuration. They may look cool but they really aren't going to be used outside the track and stack length and throat design of tuhe stack is really an art that has to be researched and experimented with...an expensive proposition most don't have the $ to properly figure out.
Even on the track, they aren't always the smart solution if the track is in farm country. The amount of dust kicked up in the area will destroy a motor in a few long weekends if the dust is of typical density during planting and harvest time...or furrowing, bailing hay or other crops using any number of implements...

Reynolds 531 brazed together would be my choice, looks sexy too....

531 is a high manganese alloy, and is always brazed, rather than welded. A significant amount of the Seeley frame's weight is from the brazing. 531 has been superseded with 631, which can be tig welded, as well as being 10% stronger than 531.

I think he meant gas bronze welded, the way Titmarsch does his frames.

 Yes, 631 is probably better than 531 now, although he XR69 frame above is using T45 steel tubing,  similar to 531 as its a high carbon manganese alloy as well, it seems to be the popular choice of tube style frame makers at present.  I think Reynolds no longer make 531..    Gas bronze or in the case of the XR69 frame, nickel bronze welded..

Yes, yes you are right but velocty stacks look so nice . I will end up with K&N filters.

[Godffery]

 + 1 on the K&N, it's the only brand I use and I would Never use velocity stacks, even on the track.

To get back to the original question regarding the Clearance:
