Unless it's been bent a long way or a short amount, many times bending cold is fine.
I should add that although I work in heavy engineering, I'm a control and electrical engineer so I'm around this kind of thing but it isn't actually my area of expertise. So I can't really comment with complete authority.
As an engineer, although I am mechanically biased & in general a designer, no doubt our outlooks are very similar. I don't think we ever stop learning in our thirst for knowledge, whilst trying not to forget first principles
Not wishing to get too far off topic, mechanical advantage, & how best to achieve it, is probably the main essence of our continued passion for Lambrettas & our enthusiasm for this Forum.
The example of extracting engine mounts, & the massive improvement in method by utilising bearings in the process to overcome thread friction needs to be tried to be believed. I must acknowledge Dave Webster (RIP) for advising me of that.
Similarly, the clutch mechanism has been shown to be improved by modification to rack & pinion. No doubt the Chiselspeed conversion is great & VFM, but my finances won't currently allow indulgence. However, I do have a motorcycle mechanism that I aim to adapt
