I purchased an EVT 4000e with a burned out motor a few months ago. I've been trying to find a place to buy a replacement, but I haven't been able to get very good service from the ones that I've called (I won't name names since the only one I remember was the most helpful - I'll be checking out David's suggestions). I've never had so much difficulty getting help to spend $700.
Anyway, the question I'm trying to have answered is this: If I upgrade from a 1500W to a 3000W motor, I understand that I'll have to do a bit of grinding of the rear swingarm, as the axle on the 3000W is a bit larger diameter. Are there any other modifications that I'll have to make? Do the electronics need to be changed out at all?
If not, the other question is, how does this impact the performance? I'm assuming that it'll have more power (good, since I'm 200 lbs), but at what cost? Is it just range?
