muffles

i bought these at the NEC yesterday....

the rear i'm happy with (got hooks for my bobbins too) but the front...first, it comes with no instructions, so i had to look up how to fit the prongs onto the forks.

once i figured out that one prong goes underneath the fork, and one goes against the side of the fork facing the engine (that's right,...right?), i got it on the front stand...but oh boy does it not look that stable! it looks like the bike can slide forward off the prongs! but then, many of the pictures (of various makes) of front paddock stand use the same design...

does anyone have any experience and can re-assure me it's not going to pop off the front stand the minute someone breathes on it....!
