gosh, i hope that motor is "mufflerless", note that it's also headerless, it's kinda tough installing these motors if both of those are attached, extra effort required.I find you setup quite unsecure... and mufflerless!
Anyway, Geauxcrush's bike is way down on forks (no space).
I don't think anything will beat a 35" 2x4 under the crashbar. (perhaps a 35" 2x2...)
my photo was included to illustrate the use of the motor ID casting as a jack point with a scissor jack. the fact that the OP's bike is closer to the floor makes the solution better, not worse. jack it up, block it, we're talking about completing this task in a matter of minutes. contrary to speculation, blocking to the exhaust system doesn't hurt a thing.
i propose a simple settlement, you use your methodology, i'll use mine.
