should be on the forum in one of the kyb threads, but the ones i remember was welding a tab on the steering head (like the yz have) and the other was door-stop rubbers screwed into the bike frame where the tubes come in contact, and the last being what you mentioned and what i had
Bolted everything together just to see how it all mates together and it seems the lower triple clamps will hit the rads first. With the triple touching the rad, there is a fair bit of distance to reach the frame and not really anything to bump off.
At this point, I'm thinking a tab welded on to the front of the steering head would be the best solution.
I was thinking this through as well. I have a home machine shop so shouldn't be overly difficult thing to accomplish. The only issue is the distance from the triple to the frame when the triple is touching the radiators. I need to spend some more time measuring things up.
Modifying the triple would be preferable as I have a spare set of YZ triples and it is easier to take a triple clamp to the welder vs the whole frame.

Ahh, here we go, post 43. There is weld a bit underneath but they butt up against the edge so they cant go anywhere. Several years on.

Thanks, I appreciate it.
I have tagged all these threads so they will appear together in the timeline ..... at least for a while. Its almost like the forum should have a dedicated section for KYB forks and fork swaps.
It is good to have my own home machine shop for this kind of project. The only thing I don't do is weld but I have a really good welder on speed-dial.
It is interesting to see the welded triple clamp blocks. Basically exactly what I was contemplating. I have even considered drilling tapping the block so an adjusting screw can be installed.
I fabbed up a plastic block and can see how it all works. There won't be a need for an adjustable screw. Your pics really helped.
As taking a triple clamp to the welder is significantly easier than hauling the entire bike down to his shop, I will be doing this steering stop mod rather than adding a block to the steering head. I also have a spare YZ triple clamp, which means that screwing the whole thing up comes with less risk/cost.
Triples went off to the welder today. I suspect the bolts would hold the aluminum blocks in place no problem but some welds will ensure the blocks don't move.
The blocks were not difficult to made although fitting everything together took a bunch of tweaking and back and forth to the milling machine. But in the end it worked out very well.

I think the biggest thing is just deciding how it should get done. In this case there were two options but its so much easier when someone can say how it has been done. Then the way is known and it just comes down to execution.
The steering stem bearings were pretty simple but more expensive than I had expected. The bottom bearing is the same and doesn't need changing but the top bearing is not a common size so the only source was direct from All Balls, which killed me on shipping. Ended up being a $70 cdn part by the time it got here.
Now just need to sort out the fork internals. Unfortunately the forks we got were from a YZ (MX bike) but will be used on an enduro bike so a bit of work needs to be done to get the spring rates and valving sorted.
The nice thing is that the SSS forks are quite easy to work on with only a couple of special tools required. I always hated servicing damping rod forks.

Really I thought it was common upper, just certain through bike shop for not much.
A mate is local KTech technician, they have a cross country valving setup and it's been hardly worth a click here or there, it just works for me in either choppy or tree roots or just giving my arms an easy time which was getting to be an issue for me.

Maybe "not common" wasn't the right terminology but I couldn't find it on eBay, Amazon or Fortnine. The only source I could find was direct from All Balls.
I was actually talking about the upper steering stem bearing.
Luckily the YZ front axle is smaller than the GasGas axle so the GasGas front wheel can be used on the YZ axle with only a new set of spacers.
