Hi everyone,

I would like to purchase a shorty for my anniversary model. What is stopping me is, I have invested in a Kern Stabi and I do not want to lose the ability to use it. Are there adapters to use it with shorties similiar to the one made for the Jekill and Hyde? How can one use the Kern Stabi with an aftermarket exhaust?
 
I had used two coupling PINS threaded into the engine case, plus a taped block of wood prior to purchasing the Jekyll & Hyde adaptors for my bike.

The use of the two coupling PINs helped to keep the Kern-Stabi aligned, in place of the missing exhaust hanger; where, the block of wood was taped to the Kern-Stabi frame so that it made contact with a low lifting point.
 
I have the extra pin also. Where exactly did you tape the block of wood and whereabouts was the wood touching under the bike?
 
Perhaps, remove the existing exhaust system and mock up where the blocks should align in order to provide a lifting point; for me, I had already installed the Jekyll & Hyde exhaust system and fabricated a temporary solution, prior to knowing about the J&H adapter kit for the Kern-Stabi frame.

The subframe does offer a couple of purchase points for lifting; maybe search the Kern-Stabi threads and see if there are any pictures, I'll check to see if that jerk scottsemone posted any pictures of his setup, prior to installing the J&K kit.
 
I was thinking, maybe an appropriate sized 12.9 class bolt tightened with a nut to the hanger. Do you think that would work?
 
There are two threaded anchors points towards the rear of the engine case; probably the same thread type as the front two (maybe M10).

Maybe go with a longer, harden steel Allen bolt to provide a contact point:

So does this mean that since I have my stock exhaust the extra M10 bolt I used is not needed. The person I purchased my Kern-Stabi from purchased and grinded the bolt down per Scott's post. I do notice getting the Kern-Stabi on/off the hanger and both bolts is a challenge
 
Using a single bolt (coupling PIN) is really all that is needed, if properly securing the eyelet to the exhaust hanger. I actually removed the additional couple PIN, I was also finding it difficult to remove the X518 carriage.

Those anchors in the rear aren’t usable with the X518. What I meant was using a single strong bolt with a nut to the exhaust hanger hole. I guess (and I might be wrong here) the exhaust hanger hole is only to keep the X518 aligned and there isn’t any pressure applied there.
 
OK I may have to do the same, was having to get assistance from my wife to get the bike on and off the Kern-Stabi with both bolts.
 
I installed the Pro-Race slip on to my 100 years edition yesterday. I also purchased the Hattech adapter for the Kern Stabi, but I don’t see a way to use the lift without first removing the Pro-Race. The Pro-Race is right below and very near the bracket holes. For a rear tyre change I’d have to remove the original exhaust anyway, and to remove the Pro-Race is much easier, so I’m still OK with having to remove the slip on, but it would be much more convenient if I could use the lift with the Pro-Race still installed. Is there anyway possible?

I'm not familiar with the Hattech exhaust adapter, but it looks very similar to the Jekyll & Hyde adapter that I installed on my Model B for when using the Kern-Stabi X-518; the two adapter pieces need to be installed as depicted below:

The problem is, the adapter is installed at the marked area, and the exhaust sits right below it, so there isn’t any space even without the spacers.

I would like to get shorter pipes (chrome) even if it means losing the Kern-Stabi lift point in the back. I just assumed I could rig a mounting point myself without the hanger.
It seems finding shorter chrome pipes is the hard part.

Can’t you just have the pipes chromed and also add cheap chrome covers as written in this link? https://www.r1800wiki.org/en/2024/03/31/auspuff-slipon/

For the Kern Stabi problem, I concluded that I will just remove 1 clamping screw for each side and remove the Pro-Race when I want to use the Kern Stabi. Then I also need to install the Hattech adapters with 10 mm spacers for each side.
