Pics of the strengthed motor mounts would be nice.
Note the engine is mounted in the frame without the front engine mounts.

Yes, the upper forward mount on the right side is still at the paintshop...
The lower won`t be used.
I think i do not need it. But i am not sure. I will test it.
The ST3 engine offers no possibility to use it.

Today i flooded the frametubes where possible with fluid film, to prevent oxydation damage.

Motor into Frame:
looking at this picture you're about 3 to 4cm too high on the front sprocket, you may not be able to lower the engine,
but you could have a smaller sprocket setup to re-direct the chain away from swingarm,
I'm sure you could borrow a chain guide from some dirt bike...it should be doable

Sprocket& swingarm-axis are exactly on the same hight.
How does it look like in original?

after looking at both pics, the front sprocket looks to be in the same spot, (my apologies for barking up the wrong tree) it just didnt look right, I should of taken the cover off and had a proper look...then the swingarm chain damage was most likely caused by a loose chain, had a look at my swingarm and it also has a little chain groove, but very small, a chain guide or nylon pad might not be a bad idea to prevent this and check chain tension more often

you could be right...when I get some time I'll remove the sprocket cover and inspect if there is any damage near swingarm bearing, I still think this is not a design fault, but a maintenance issue
