SELF INTRODUCTION: Hi Dan, thanks for your time and energy spent on this new board. I hope you will give me a waiver on the email account, I have used gmail so long I don't have a clue what my service provider account is.
I just returned home from a 2 week trip in New Mexico, have a few good pix, can't wait to share my off-highway traveling. Got to put 1400 miles on the scoot.

Best, Bob Davidson

I suspect that the twisted stock is purchased that way. Both twists go the same direction.
Maybe its just me, but if I went to the trouble of twisting some square stock, I would make some going in each direction,
and have symmetrical twist each side.

Thanks guys, some great comments and some even better ideas, I do like that springer and yes I would want the twist going in opposite directions..... :think:

Just for the record, I already have a plan for the FZ750 project build but I am still thinking through the diamond frame build......the frame has mounts for a GS550 but I've ben looking at a GS750 motor....but then again I could easily change the motor mounts........ :whistle:

I'm feeling better now so have been doing some trick machining (like yer do) and hopefully I'll get my bike table modifications finished before Christmas.....then I'll be going full on with the FZ750 build..... :banana-dance:

I don't know who built that Springer but something is horribly wrong with it. Notice that both the rebound and compression springs are both at almost complete compression with no room left between the coils for any 'spring' action to take place. I've seen a few like this in some of the magazines. Looks like the builder was way off on the length of his spring rods or the springs were way to long for the rods they used. I'm totally amazed when I see stuff like this in the marketplace. Cool idea but poor execution. A custom Springer should at least provide a little suspension.

Well that explains a lot. many Springer builders use a set of de-tempered springs during mockups and on displays so they can take the forks apart without using a spring compressor. To me however those don't look like mockup springs.
