HOPEFULLY HELPFUL TIPS FOR INSTALLING WUNDERLICH (AND MAYBE OTHER BRANDS) HANDGUARDS
I removed my recently added Wunderlich handguards today. That's my preference (see my post 16 in
https://www.bmw-scooters.com/threads/first-modifications.3291/ if you're curious), and not relevant to this post. My point here, instead, is that I took some pics this morning, while putting things back to stock, that I hope folks installing handguards may find useful. These pertain to the Wunderlich guards, but may also be relevant to other brands.
1) You may want to note the gap between the clamps and the switchgear.
Because you will be loosening these clamps, you may wind up moving them sideways. The stock gap (which is relevant to the openings in the handlebar cover, although there is extra room in that piece of plastic) is about 13mm:
(I could tell where this was today, when I was putting things back, because I looked for -- and found -- a very straight line of road dust, etc., which had accumulated in the last year, next to where those clamps had resided.)
2) You may want to first note the angle of the levers that you've been comfortable with.
Again, because you will be loosening the clamps that hold the levers in place, you may want to measure that angle.
With the handlebars centered, pick a point -- say, the major bend in the levers, and a right-angle position on the grips, e.g.:
Because you won't be able to slide that kind of inclinometer in position with the handguards in place, you may want to resort to some kind of flat edge, e.g., a ruler, a level, etc.:
You may have to adjust those angles in order for proper handguard clearance of whatever windscreen you have on, with the handlebars at full lock, but at least you'll have a baseline to work with, to know how much you're changing the angle, and so forth.
And note that this angle may be different between the left and right levers -- there's not perfect symmetry in the layout here -- so measure both sides.
3) Make sure the bottom clamp bolt is snug.
As I wrote in post 18 in
https://www.bmw-scooters.com/threads/first-modifications.3291/, I think the problem I had with not being able to fully tighten the left clamp was because the bottom bolt in it was too loose. The Wunderlich guards replace the top clamp bolt, which you then tighten up a bunch. But in order for that to really lock the clamp (and everything connected to it) in place, I think the bottom bolt has to be seated pretty well first, i.e., just barely allowing the clamp to rotate to your desired position, before completely tightening that top replacement bolt.
That's all I got.
