GreenMantis was hypothetically saying if a company like TrailTech made a bolt-on charging system for non-genny engines, there would be no need
to buy the rare and ridiculously wide genny engine itself. For example, Phantom Bikes has a bolt-on system already (albeit just for a light).
There was a member of the other forum who hand-made parts for a bolt-on charging system as well - and was going to sell it - but changed his mind.
His system was quite compact and required only a small cut-out mod to the fan shroud and a Holmes Hobbies voltage regulator ($15).
It's obviously possible to have a bolt-on charging system on the standard HS142. We just need someone to make it!
