Not 100% sure. Went to a local store with huge supply of o-rings, took old ones with me. The numbers 9.?? x 1.8 stand out, but I'll have to look at receipt later when I'm home. Now if I could only find a store that carries odd brake line parts!

10x1.7mm is the correct size, so yours is pretty close. I went with these

Did yours have washers in there as well? Mine did not, but I see some parts diagrams with them, some without. I don't see how they would fit anyways, tight fit as-is.

edwardmorris · « **Reply #203 on:** February 17, 2015, 06:40:11 PM »

Don't think so, I'll check and see. All the h/w is zinced up and packed away in ziplocs for now. The washers are 0.1 and 0.2 mm respectively, so even if they were on, I bet they got vaporized

Davez134 · « **Reply #204 on:** February 17, 2015, 09:18:27 PM »

No worries. I'm not going to put any in there. Just wondering.

Sweet! Should be a speedy build from here on...

Yeah. This was a big step. The moment I have been waiting for for 6 months!

I'm thinking you need to take a week off from work and turn this baby into a fully dressed roller! All the hard parts are done, so it could go quickly from here-

I work today, but have Tuesday through Friday off. Should get a lot done. Hagon shocks are ordered and hopefully will be here before Friday.

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.

edwardmorris · « **Reply #213 on:** February 24, 2015, 10:03:48 PM »

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

Davez134 · « **Reply #214 on:** February 24, 2015, 10:24:36 PM »

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!

Davez134 · « **Reply #215 on:** February 25, 2015, 12:07:03 PM »

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!

Shocks came in today. Now stance is right!

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

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.
