Neat modification. Rotate it 180 deg to put the pinch bolt on the inside and its even tidier Smile

[QUOTE=theone&onlymin] Is this a solution to internal threads on Loops? Saw it on a beemer somewhere.

Apologies for mentioning BMW, but I've recently bought a "proper" remover for the finned ring nuts on the R80RT. After a struggle, it worked on the first one, but I ended up having to belt the living daylights out of the other one, so I'll need two new finned nuts anyway. I suppose the tool will come into it's own for fitting them, but I may consider a mod as per TOAOMin.

Just to add, I also got the special tool for my R80. To start with I had to cut slots in the original finned nuts with a microsaw blade, to release the pressure to get them off. After cleaning up the head threads, new finned exhaust nuts were put on with copious amounts of copper slip.

At least once a year, both finned nuts were loosened and a bit more copper slip added if necessary and then retightened, to make sure they can still move.

Those threaded exhaust flanges have always been a nightmare. I used to have Nortons.
They either came undone all by themselves, or seized up completely.

Even worse if you had the joke "lock washers" installed. They let the collars go slack but not fall off altogether so they wrecked the threads in the head.

I had the exhaust ports recut by a firm in London and oversize bronze collars fitted which sorted it once and for all. Another fix was bronze inserts.
