it doesn't always seal. so the options are to REALLY glob it on and make a mess or risk doing the job multiple times. how many side covers have you removed? it's a real pain to get that thing off. even WITH a puller. sometimes i wonder if this is going to be the time that i break a cover.I think that there is nothing wrong with sealer gasket. Why pay for a ducati gasket when you can create one with a good quality silicon.
