My moby engine mounts look like they can move a bit, the steel parts that holds the urethane bushings.
I want to reinforce them to the frame, will probably braze some kind of support structure.
What have you done to make the engine mount assembly more rigid? (edited)
I welded some 1/8" flat bar on the backside of the two hanging mounts, connecting them essentially.
I don't know if is necessary because I also welded some flat bar connecting the bottom of the tank to the frame side rail things that the engine mounts are welded to.
^^^ Thats similar to what I have seen tomahawk do on his moby builds if thats worth anything.
I was thinking of doing that plus the swingarm mount tabs up to the frame as well.
I had a minarelli v1 welded on
That really strengthened it up
I welded a plate across the bottom of the frame cut out from 1 side mount to the other.
A triangular-shaped piece on both sides from the mount to the underside of the frame rail would be much more effective (structurally) than that bar across the 2 motor mounts. That will do little to reduce the twist you're trying to eliminate.
Pile it up thick :)
Welding them up for racing then you may as well remove the stamped metal silentbloc holders and weld on the threaded half of a 32mm split shaft collar. Makes mount changing so much easier when you rip through a couple of sets a season.
With a modified skateboard wheel with bearings the bolt rides on, I've never swapped them out. They don't die.
It's really cool
Those skate wheels work pretty good as chain rollers , too . ;)
Yep - 608-2rs bearings for the win (so inexpensive as well)
