ezrider, a quick way to solve your problem is replace the stock bolt with a non-shoulder bolt that will allow you tighten it down enough to have some drag on the pivot. My buddy lost the factory bolt on his 450 and we did this with good results. I'm not sure it's a good long term solution, but it worked on his until he sold the bike.
Once I got used to it, I kind of like the 'auto-retract'. My KTM buddies give me a hard time about it, but I tell them it makes me faster than them from a start.
LeFrog, we met at the Ellsworth and Brown Chevron awhile ago. I have a 550. I can help you with welding that side stand if you need it.
