For XS650 motor, but not quite...

http://www.xs650.com/forum/showthread.p ... featherbed

That's the guy I got my frame from. It's really nice for a custom build.

He started a very similar thread in the TriumphRat.Net Classic & Vintage section, dut with the emphasis on the Triumph lump with no mention of the Yamaha alternative.

Seems like a decent frame build, and allows all the engine, front end & swingarm mounting appurtenances to be customised to the specific engine, swingarm & forks to be used for any specific built without having to further adapt.

Great idea to have a featherbed builder here in the 'states...

Modern triumph motor in a feathered frame would be nice

this was my last Triton build, I was manufacturing Slimline frames at the time so I made one to accomodate the "New" engine. It was a very nice bike so much so that Triumph NZ was asking me to make a run of rolling chassis's to supply them with, so they could fit new engines to them , I declined the offer, I sold the bike to an Englishmen for $24,000 whose intentions was to use it as a donor bike to manufacture a short run of 10 bikes, I never saw any evidence that the bikes were ever built. I dont believe they were.

Beautiful Triton there Madass.

The frame in the xs 650 link looks a little scary to me. The coped ends of the tubing look to be very crudely done with an angle grinder as near as I can tell from the photo, which is not a close up. There appears to be big gaps here, which presumably will get filled with weld. This is not a way to make a strong weld, especially if the plan is to tig weld,as is now the norm. Might get away with it on the 1/8"thick mild steel frame, but it would be a real mess to deal with in thin wall chrome moly.

Looks like the tacks are done in mig. A customer of mine brings me Ss hotrod exhaust systems for welding. He does the fitting and tacking. He was doing the tacks in mig which made it really difficult. Even tho his fits were good, he had these big carbunkles of mig weld everywhere to try to blend away. I now have him tacking them in tig, much better, just tiny little tacks that disappear into the main weld.

Im all for do it yourself, but the welds and fits are pretty important to life and limb.
