This guy tested several different products for gluing rubber to metal. In my opinion the CA type super glue came out best.
I'm gonna try Loctite Super Glue Ultra Gel for gluing my repro H1 rubber mounts.

I use loctite 404, only because it's what they use in their o-ring splicing kit... It is not flexible though.

for those interested, i called Amathane (recently acquired by a company called Pro-Thane) in Milton, ON today and they sell kits. smallest kits being 1 quart selling from $80-90. 2 and 3 part kits are what are available. the 2 part kits are ordered when you know the Shore Hardness # you want. the 3 part allows you to play with the B and C catalyst ratios (part A being the polymer) allowing you to create a range of hardnesses but need to be precisely weighed to the +/- 0.5 gram. the 2 part can be measured out by volume (however by weight is preferred). generally engine mount Shore Hardness #'s in an automotive application are rated between 70A and 90A. they can measure the Shore hardness of a sample in house using a device called a Durometer. below is a link illustrating the Shore Hardness range: www.smooth-on.com/Documents-Duromete/c1351_1370/index.html

Wow, it's gone up in price! We were getting a gallon for that money $15 years ago... I guess the same could be said about a gallon of paint too though.

Perhaps but more likely I'm just not with the times... It's good stuff though, as long as you de-gas it after mixing. One guy from work was making his skateboard wheels and he said they stood up just as well as the purchased wheels from the skateboard shops.

well, i installed 6 silent blocks with 3/8" id tubular spacers. i carefully cut the tubes so as not to deform or pinch the silent blocks when the mount bolts were torqued. the top fwd ones are eccentric and had to use a pair of new reproduction german replacements rubbers. I bonded them to the original spacer tubes with Threebond handlebar grip glue (which i believe is the same as 3M's 1300L adhesive... looks and smells the same).
the cases had been floating so much on the deteriorated rubber mounts putting side loads on the chain which caused it shed most of the o-rings. i removed the chain and laid it flat on the floor noticing it was curved quite badly compared to the new chain.
