Isolastic Questions

Did you modify the front tube for MK3 verniers so it was the same both sides or did you buy the Vernier kit that fits the front tube unmodified with unequal sides.

To stop the vernier adjustment moving the central bolt needs to be tightened, this then holds it all in place. 

I will have to look at my spares box and see if it matters, if you did not have to force anything then you should be ok. I will check tomorrow, Your only other issue is long term adjustment will differ from the factory so over a few adjustments the engine/swingarm will be moved differently, periodic lining up of the wheels is needed anyway and would cover that.

The engine is in a cradle with the swingarm attached to it, this whole assembly only connects to the frame through the iso's. As you adjust the iso's they move slightly as the wear in the PTFE washers is taken up and so move the cradle with swing arm attached. If both verniers are on one side the whole assembly gets moved over, if one is on the left and the other on the right then the whole assembly pivots as the wear is taken up. Its only thou's but over time and at the end of the back wheel it is more.

It's the front one, so get it out and put it right. Not that hard to do. 

Turn it around correctly, my parts bin only has proper MK3 ISO bits in it but there is enough difference in thickness sizes of parts between the 2 sides to make it safer to get it right.
