See if it's feasible to buy a small one for a car and mod it to your specs, or mod a rack from another bike. Anything can be done as long as it's done properly.
Bolts and nuts would be the way to go but if u don't have the space consider a good contact adhesive (thinly applied to both sides) and for extra security a few small aluminium pop rivets.
After u did the maintenance on the master cylinder was there any noticeable improvement in feel ?
My fluid is good but i'm thinking about doing both fluids anyway cos dealers say they do things but do they really ???
Personally i have no need to try this kit cos i wear boots and my shifting is always measured but from what I've read it works to varying degrees....depending on bike make/ bike model and owner style, riding experience, etc etc.
Mix and match of OEM spring/ Rott spring and ceramic bearing/steel...
I have this particular stand and it's great, but If your going to fab a stand consider the possibility of also being able to invert the stand and hoist your bike from a strong horizontal roof beam, or whatever.....this is a hypothetical only.
If u go in this direction please post pics.
PS. check...
