I don't think this happens to someone who thinks they are a mechanic and screw it up, IMO this mistake happens to a person who
knows they are no mechanic, but is cheap and it's just 'too simple' a job. It's also the person who goes to Wal-mart and gets the totally wrong battery because the part number is 'close enough'
This doesn't happen to BMW's because those owners go to the dealer to set the air pressure in the tires
The same person could probably do a slightly more difficult task because they'd actually be paying attention to the details... and then still torque the drain plug to 35
ft/lbs 'because the manual said so'
Lunatics totally right, but the word is "incompetent" and the problem with that is exactly in the definition. I am 100% for people learning to be self-sufficient mechanics, but the thing about motorcycles is... They'll kill you.
as a side note, my wanna-be electrical engineering brain is super curious to see how an ECM gets "cooked" from reverse polarity? I can see why the IGN fuse blows, even why the coil in the IGN relay burns (same reason actually), but without a high current
short, the solid state ECM should be fine?
Maybe the IC for the fan signal wire would overload but the bike would still run. If anyone has one I'll pay shipping just to burn the gel out of it because I'm a huge geek
In My Opinion
