Problem is that the sidestand is very difficult to prevent from turning on the tube, it is very high stress on the clamp when the bike lean on the sidestand. I would reconfigure the support, cut off and reweld to something like on John's side stand.
But be particular with the bikes angle when on the stand, too little and it easily tip over the wrong way. Also if you have the older stand with no foot, just an knife edge, it is way better to weld on a foot as the knife edge has a nasty tendency to sink through the road surface especially in hot weather! And the bike tips over when that happens! Listen to the guys, there is better sidestands to fit.
Also watch out for a leaking carb when on the side stand! The float has to have ample room sideways so it does not hang up on the walls in the bowl (meaning fitting without much play on the pivot pin), and the needle seat needs to be perfect in order for the carb to seal when leaning stationary.
Be very aware that original rubber footboard mats do swell up and breaks apart when subjected to gas! When the bike is on the center stand, drips from the carb does not reach the footboard so if a sidestand is mounted you can be in for a really heartbreaking surprise when the original footboard mat is ruined! I managed to save mine sort of, after a full year of gentle gradual press in a vice between soaking paper and cardboard...
