The Can-Am Spyder (factory accessory) 1" riser block (which is actually a half inch upward and a half inch aft repositioning of the handlebars) is incompatible with the (marvelous) CalSci windshields. Your clutch lever (in the extended position) will contact the left edge of the windshield a full 1-3/4" before your tires reach the right-turn limit. I tried repositioning the clutch lever, shimming the windshield screws, etc. with no appreciable improvement. According to Mark Lawrence (at CalSci) when I informed him of the anomaly:
"I believe you have to choose between your risers and the windshield. The 1" risers are not very popular, according to my information: people who want risers are tending to go for more like 3" or 4". I've run into issues like this on other bikes, and my general policy is I don't compromise the wind protection for most so that the shield is compatible with accessories installed by a few."
I would actually prefer the 3" or 4" risers but fear that such an installation might void (or partially void) the factory warranty. In any case, according to Mark's information sources, it sounds like there are only a few of us with the Can-Am 1" riser block... so this incompatibility issue won't have any negative affect on the masses. But take heed if you do have the Can-Am 1" riser block. I'm really disappointed. The CalSci windshield looked wonderful on my Spyder. But I do a lot of close quarter maneuvering (parking lots etc)... and not being able to cut the wheels fully to the right causes me a lot of unnecessary grief and skinned knuckles... and the Spyder already has too large a turning radius to start with. I'm opting to keep my 1" Can-Am riser block and await the unveiling of the Can-Am Spyder touring windshield (due to be released next spring I think). It looks a bit too touring'ish in my opinion but since the riser block and the touring windshield will both be coming from BRP/Can-Am, there's a real good chance that there won't be any clutch/windshield incompatibility issues.
Ride 'em if you got 'em.
