I have a 1971 Yamaha DT1 MX that I am in the process of restoring. When I got the bike mostly apart I noticed that the side (kick) stand was touching the swingarm when the bike was up on a MX stand. I never noticed it before. Should the sidestand be rubbing the swing arm? I assume not. Does anyone have any experience with this issue? If so how did you fix it?

My DT400 does the exact same thing. For now I simply found a large rubber washer that I slipped over the foot of the kickstand to acts as a damper between the stand and the swing arm. My future plan is to have my son put a spot of weld on the pivot tab so that I can take a grinder and shape the bead of weld to act as a raised position stop, preventing it from pivoting all the way against the swingbarm.

The kick stand is traveling too far back.
You can build up the metal with a welder in one of these two locations.

I had simular problems with my RT kick stand. The bracket for mine had been broken sometime in the past and welded back on. I ground out the old weld, welded back in position and added weld the bracket to stop the kick stand in the correct position up and down.

Also commonly happens if someone installed slightly longer shocks... fix is the same.

Thanks for the input. I had come to that same conclusion buts it really helps to get some advice from people who have been there done that.... Thanks Again All......
