So I ordered a longer cable from lectron for my 14' cr165 since the stock one is way short even without the lectron and even shorter with it. The cable wasn't perfect for the 125 so I've been playing with adapters from lectron as well as the cable.
Long story short my 14' wr300 cable is a perfect fit on the 125. It wraps through the forks and up behind the number plate and has adjustment on the cable and carb in both directions, it does not thread into the carb. You keep the brass lectron adapter. The pull is just as easy as the stock 125 cable.
The lectron cable fits on the 300 nicely but may have some rubbing issues with the upper motor mount bolts and the cable, it threads into a standard lectron fitting not the brass fitting. It has adjustment in both directions as well. It sounds like Kevin at lectron is working on an updated cable that will thread in as well as take care of some clearance issues. I previously ran the stock cable but used a heat gun to form a low profile 90 which worked well to clear the motor mount, I didn't notice any more resistance in the throttle twist. I did notice slightly more resistance with the lectron cable but this could just need to be broken in a bit.
