Assuming you have the correct brackets, if it's just a hair off you'll need a second set of hands to "lift" the engine up so you can slide the bolts through (the frame actually is THAT flexible). If it's more than a hair off you probably have the wrong generation of brackets.
"Ride Safe, Chop Safer" Motorcycles are not unsafe. However; they are extremely unforgiving of inattention, incompetence, ignorance, and stupidity.
Dismantling, sawzalling, and rattle canning does not make a bobber.
Those are STEPS toward customizing, not customizing unto itself.
