I have now got all the studs to replace the 6mm bolts on the cylinder and head except for the 6mmx102mm. That one is discontinued and I can't find the one suggested by Colin from the KVF400. however I did find a part number from a generator and it turns out there are only 2 left in Japan and then they will also be discontinued. The order is placed today for the last 2, fingers crossed I get them.

I have been working on the reassembly of the guages. I have got tacho together and overall happy except for the crimp ring. I still have the original and try to reuse it on the speedo. I would of got the speedo back together today as well except I didn't notice until I was trying to put it all together that the internal bevel had some slight suface rust. So thats now drying and will be together tomorrow evening.

Finished both guages now and very happy. Managed to manipulate the rubber to hide some of the crimp marks. All I need now is rubber for trip meter.

+1 Tim, excellent work. ;D
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

I am just waiting on the 6mmx102mm stud to arrive and then the engine goes together, gets some paint and then into the frame.

Just placed an order for a set IKON 7610 shocks, still waiting on the studs, but hope to have engine painted and assembled by the end of the week or weekend or next week knowing my luck.

Apart from how frustrating the rings are to close up, the other frustrating things where paying $10.50 for a can of red paint for the tips of the needles and only using the equivalent of 2 drops. And also having to buy a $11 spray can to touch up the internal bezel , the nozzle was pressed for all of 5 seconds and you can bearly see it, however it would of looked half done without it.

I had similar trouble with getting the SS ring close properly on the K2 gauges so I stuck with the stock ones for the K3. Surprisingly, the inner bevels on the K2 gauges were spotless, but three other sets I've opened up since have been crap. I found a small vendor online that made mini spray cans of paint that had the perfect color match, plus the can size is tiny, so cheap and not wasteful. Its basically like a supply store for small hobby projects and stuff, can't remember the name.

Good choice Tim, I've just installed new Ikon 3612 series shocks on my Harley Sportster, and they're one hell of an improvement over the POS Progressive 412's that were on it! Cheers, Terry. ;D

Hey Guys...I've always been a fan of Koni's and understand the Ikon have evolved from them.

Are the Ikons made in Oz? if so, are you guys getting a good deal on them?

Stev-o, yes they are still made oz. And what I like is that they are made in a country town. The service is great, you can ring them direct and talk about what you want and how you ride and then they build your shocks.

Mine was $565.50 delivered and I am certain that price is for Australia wide.

You will be more than happy with the Ikons, great firm to deal with as well when wanting a custom set up.
They do say assembled in Australia, so must source the parts.

For those of us in the US, Dave Gardner is a great person to deal with.  He goes over the specs with you in detail to make sure the shocks will fit and perform for your bike/weight/application.  It's also great that these shocks are rebuildable.

I think I am missing a dowel pin from one one of the pump lines. Also I think the pump drive gear on the kick starter shaft is on the wrong way.

Also I was trying to install the neutral switch and the only oring that is close to fitting is too large on the OD. It fits fine around the switch but wont fit in the case. Does this mean i have installed the wrong oring somewhere else? I am hoping not. The gasket kit came from Yamiya so I am confident its correct.

For these small quantities I use nail varnish.

I had similar trouble with getting the SS ring close properly on the K2 gauges so I stuck with the stock ones for the K3. Surprisingly, the inner bevels on the K2 gauges were spotless, but three other sets I've opened up since have been crap. I found a small vendor online that made mini spray cans of paint that had the perfect color match, plus the can size is tiny, so cheap and not wasteful.

Here is some info on N switch orings from Hondaman:

http://forums.sohc4.net/index.php/topic,147098.msg1693272.html#msg1693272

meaning you can go different size since Honda done it too.

Also I was trying to install the neutral switch and the only oring that is close to fitting is too large on the OD. It fits fine around the switch but wont fit in the case. Does this mean i have installed the wrong oring somewhere else? I am hoping not. The gasket kit came from Yamiya so I am confident its correct.

Got the last 2 studs today and got the engine painted. I will get the head on tomorrow and re-torque on Sunday. Also found an o-ring that fits for the neutral switch but now it wont push in far enough.

Is the ball on the end seated in the detent on the shifter mechanism Tim? If it is, give it a gentle tap around the outside (alloy) part, not the plastic inner. Try using a socket. Cheers, Terry. ;D
