I got the gas/electric going and I like it, goes around 20 mph I guess, but after a hald mile or so, it just slows down even with a steady 27v going into the batteries from the alternator. If I back off the twist grip e-thottle and jam it on full- it scoots ahead, but again,slowly slows down. Yesterday, I took readings at the motor leads and the meter shows the dwindling power being fed to the motor.
Ever hear of this before? I am about to rip that miserable black box out and go to a simpler on/off switch, but thought maybe it is the throttle? Here is a pic of the bike:
I am using the HF79 (behind the black shopping bags/ gastank above in the red bag) driving a Ford alternator (no regulator used but fed 12v off ONE batt. to the field circut) with the engine rpm set to provide 30 volts max (engine has a handy max speed setscrew),the alternator feeds directly to the battery- keeping it charged.
I had used a Delco alternator with a 24v regulator but I wrecked one reg. and had a dud to replace it, these worked OK (seemed to take a lot of engine power to run though), so wanting to get the bike going, I went to the Ford unit.
The HF seems much happier (loadwise) as it makes 30v at a very fast idle.
The engine is hidden because gas power bikes have always been illegal in NY, and even though it is electric, I want to go covert to avoid problems. It is pretty quiet but not silent- went to a bit of effort to silence intake and exhaust. Just hear the engine clatter mostly now.
