420 auto

Well I finally was able to ride this past weekend and my buddy that has the 81 420 auto took that out for a Moto . When we got back to the barn he was saying how much it beat him up on his track . It looks like it has remote reservoir Ohlins on the back and 35mm front forks. I know it has about 10” travel on both ends and would like to keep this ride height but what worthwhile improvements can be made to these forks or should he start looking to replace the forks with 40mm forks ? To keep the ride height close , I assume we would be looking for wr forks but what years ? Would the triple clamps for 40 mm forks be an easy swap ? Or what would we need ? Has anyone tried a front disc brake on this bike ? As this track has a lot of down hill off camber turns ant the auto free wheels .any direction wouldbe appreciated . Thanks , Charlie .

no problem 40 mm WR !easy !
