I think I got sent the wrong axle, possibly from a F bike?


Temporary (way short) shocks till mine arrive, but it's on its own wheels

Just got another axle on the bay supposedly from a 72. Hopefully it fits. Everything else on here is exactly right according to parts fiche.

Can't tell from the pix, but you do have the spacer on the right side of the bike, correct? Wish I'd checked on here sooner, Jerimiah here was selling a complete axle with the spacer and chain adjusters for $16 shipped  8)

Yeah I have the spacer. Everything is there. Axle is just too long. Even without the spacer it wouldn't matter though, as it is the length outside the swingarm. Oh well, hope new one works!

Can someone with a early k bike measure their rear axle length when you get a chance? Searches just keep giving me the diameter. Thanks!

Those gold wheels will go nice with the gold decal on the tank.  The Polynesian Blue looks awesome.

What handlebars are those? I'm considering black anodized Renthals for my K3, but don't wanna give up the drilled kind to conceal control wiring. I have one in mind on ebay that I'm thinking about getting PC'd.

They are renthal low rise (not ultra low) black. I am drilling these. I drilled my last set on my other bike, and while wires were tight, they all fit fine. Going to tackle that tomorrow, so... Pics to follow ;D 8)

Here ya go. Lined up controls where I wanted them, marked and drilled out. Obviously make sure to file smooth all edges. It's harder with these bars cause they are thicker aluminum, so the internal clearance is smaller, but here's evidence it works. Just be patient.

Installed rebuilt oil lines. The return line was a touch long and didn't bend perfectly smooth, causing it to just barely "flatten" is this ok or should I find another?

In my opinion that doesn't look too severe of a kink to hurt flow at all. From the pics alone I'd say leave it.

Winter and work won't let me keep up with you  >:( >:( Jealous  :P

Looking good, especially that dash label, painted over the HONDA label? Also, glad you got the slingshot lines, I recall reading a thread where no one was getting through on their site. My K3 is going to be kitted pretty much like this one so I can't whine about the timing  :P Check PMs please.

Beautiful work, Dave.  Did you repaint the controls yourself?  If so, how did you handle the red detailed writing?

Dave, I noticed the carb's aren't on yet. Did you get any carb->head boots yet? I'm exploring options on that, I have a full set of NOS ones for my K2, and the damned things feel hard while still in packaging  :o and the clamps and screws are gnarly at best. Not sure about the boots yet, but for the clamps, I'm considering these stainless ones, worth checking out if you haven't already got that part squared away.

I didn't have any controls to paint.  ;D I cheated, these are from yamiya.

Thanks for that. I have nos boots in packaging as well. They feel hard, but it was the same way with my other bike, comparing to old ones, they are actually very pliable. I will probablly get clamps like that. Have factory ones, but they just feel so flimsy.

Waiting on a few small parts to button up wiring, as well as a new inner oil line. Can't do much else today so I couldn't help myself...mocked it up (except front fender)

Ha!

For anyone curious, the instructions say (and demonstrate with pix) to install them with the flanges on the head, then jam a long wooden rod up the rear of the pipes, then make them bend to fit at the pillion foot rest :o :o :o :o
