Hello, fellow members. I am new to this forum, but not to owning and fixing Recons. I searched high and low across this forum and Google in general, so please don't flog me if I missed the answer to my question somewhere.
Backstory: I own two other Recons, a 2001 and a 2021. Both have been great, but they're manual shifts, so I am really new to this system.
I picked up a 2007 "parts bike" a few weeks ago, that had been sitting outside, disassembled for several years for $50. After bringing it home, I realized it had spark and compression, so I spent a few hundred bucks on parts, including tires, brakes, carb, and a few cosmetic parts, and what do you know, it runs great!
Initially, it wouldn't shift, at all with the electronic system. It had code 3 present. Turned out it wasn't the angle sensor. It was actually a bad wiring connection on the pin to the harness for the wire the supplies 5VDC to the angle sensor at the ECU. Once I slightly bent the pin, everything came up and worked just fine. For good measure, I replaced the angle sensor, since it was obvious that water had been in and behind the sensor at some point. And since it was cheap, I would rather do it now, than on vacation in the mountains somewhere.
Initially, the shifting system was working flawlessly, but now I am having intermittent trouble where the bike will go into first gear from neutral, then right back to neutral when the shifter returns. When it happens, it happens constantly. But other time, I can jump on it and it works perfectly. When the problem is occurring, I can use the emergency shifter and put pressure on the shifter, slowing the return after the upshift and it seems to work ok when I do that, as long as I apply just the right amount of pressure.
There is never a problem going into reverse, or from reverse to neutral. It really acts like the motor is just pulling the shift shaft a little too far in the other direction when it's returning after an upshift.
Does anyone know if there's an adjustment for the shift motor, or alternatively, can someone probe the return voltage from the angle sensor on a working bike to tell me what the return voltage should be when the shifter is in it's normal position (basically key-on, engine off, no shifting taking place)? The return wire is yellow with a blue stripe.
Thanks, in advance for the help. I have literally exhausted everything else I can think of at this point.
