Yeah that will reduce the travel an increase the spring preload. You may or may not be able to compensate for that depending on if there are any grooves left above the current setting. You would really need to remove springs from a shock fit it back on bike, compress the shock fully, factoring in some compression of the bump stop, then see how close tyre is. If there's no real gap then you would need to shorten/limit the stroke and maybe even the bodies. Kinda can get costly if you cant DIY but they are Ohlins so its worth doing i guess. If you have got some space between fender and tyre then you can get away with the simple solution of swapping the eyes for shorter ones if they are currently not already short and then not have to worry about increased spring preload and loss of stroke etc.. All the early 80's Husky ones i have had were fitted with 46.5mm eyes.
How long are the current eyes you have fitted?
