Those lines look great, should be bulletproof.

Looks like uncoated stainless braid, watch out for chafing where they ride against the case, frame,and swingarm, that'll eat through your paint right quick if you let it.

Mystic, thanks for that I will work out some unobtrusive way to prtect the frame.

Terry the hoses weren't cheap but they should be bulletproof as mystic said. Cost $130 each and I would not of got them if I couldn't claim them through work.

Just got these as well, could be a busy weekend coming up. The oil tank is in a molasses bath.

Good work Tim, and I'm glad I didn't go to Pirtek, that price seems a little high, but I'm sure they're worth it. I'll just have to slum it with my 5 dollar ENZED hoses......

I had a look at Yamiya and mine are still cheaper. Their SS braided only hane a hose clamp with shiny cover.

Yeah, the Carpy ones were el cheap I braided hose with shiny covers over hose clamps, I'll use them with the black ENZED hose just because they look pretty.

Ok, I need to revisit the question of the neutral switch wire. Mystic I appreciate the help but it didn't quite give me a picture of where the physical wire runs. I have a wiring diagram and can read them with ease. I have marked up a drawing of where I think there are 2 possibilities of running the wire.
Option A - orange line
Option B - Blue Line

if its different these please let me know.

Both of my bikes are ran the way of the blue line.

Thanks Dave, the more I looked at it the more I thought the same.

Finally got the oil cleaned and painted. I used matt black and then after looking at it I thought it should of been gloss black. I am also having trouble finding the rubber seals for where the oil hoses connect to the tank. I am thinking they need to be a flat rubber seal.

mystic_1 · « **Reply #511 on:** February 13, 2016, 01:45:42 AM »

No, the sealing washers where the lines meet the tank are aluminium crush washers, similar to the oil drain plug washers.

G'Day Tim, it's the blue line mate, and no, there are no rubber seals, there should be a soft aluminum washer per threaded hose fitting. Make sure the old ones aren't still in your fittings, they tend to spread a bit when the fittings are torqued on, and they're hard to see. When I scored two engines on Thursday I ended up with 5 oil hoses, and in those oil hoses today I found enough aluminum washers for Mike's bike's two hoses........ Cheers, Terry.

timbo750 · « **Reply #513 on:** February 13, 2016, 04:07:10 AM »

That explains a lot. One hose looks like a flat surface of the threaded fitting and the other has an unexplained groove which most likely still has the aluminum washer in there. Now where to I find these washers??

Terry in Australia · « **Reply #514 on:** February 13, 2016, 04:19:04 AM »

Try an engineering supply store Tim, soft copper washers would be fine too, beware that one fitting has a smaller ID than the other one, so you may need to file one to make it fit. The OEM washer is about 1 mm thick and the hole needs to be at least as big as the ID of the hose so as not to restrict flow. Cheers, Terry.

timbo750 · « **Reply #515 on:** February 13, 2016, 02:47:27 PM »

I managed to get a sprocket cover but noticed something that doesn't seem right. The is a small 'cut out' near where it fits to the case. Now when I say 'cut out' I am using that term to desribe it because it loos like it was cast that way.

Davez134 · « **Reply #516 on:** February 13, 2016, 03:18:49 PM »

Wiring has to come out somewhere

That makes a lot of sense. I have nothing to go by for where the electrics run. This bike had wires hanging out of all sorts of places I got it.

Davez134 · « **Reply #518 on:** February 13, 2016, 06:37:15 PM »

No worries. If you need any more pics of wire/routing let me know.

timbo750 · « **Reply #519 on:** February 13, 2016, 08:09:42 PM »

Dave , I know the points wires will run under the engine but do you cable them to the frame?

Davez134 · « **Reply #520 on:** February 13, 2016, 08:20:58 PM »

I personally did not cable it to bottom frame section. I ran it close to frame and cable tied it near where it connects near oil tank. Out of sight

timbo750 · « **Reply #521 on:** February 13, 2016, 08:22:01 PM »

That sounds better.

mystic_1 · « **Reply #522 on:** February 14, 2016, 10:48:22 AM »

For the wires that run underneath the motor, like the neutral switch and the point wiring, there are supposed to be wire clips that mount under some of the bolt heads and hold the wires in place, one goes on the oil pan, and there's another one down there somewhere that I don't remember right now.

I think I have a diagram somewhere or a picture that shows these, but I am NOT at home right now and I will post it when I am able.

Terry in Australia · « **Reply #523 on:** February 14, 2016, 12:28:12 PM »

Yep, the other clip lives under the sprocket cover to hold all the wiring away from the front sprocket. Cheers, Terry.

timbo750 · « **Reply #524 on:** February 14, 2016, 12:51:07 PM »

Photos of those clips would be great if you have them.
