A few updates:
The kids are putting the miles on and only a few minor issues so far....but they are burning through tanks of gas pretty quick just tootling around the neighborhood.
My daughter used a GPS speedo app and measured 30mph! I was expecting 22 based on my calculations, but it is possible the engine is turning a bit faster than the governed spec. I have a spare tach/speedo, but since it requires 12V it will be a small project to add it.
The bolts holding the wheels to the hubs like to back out, so they now check them regularly and have added lock washers. One set was completely gone and ended up shearing the bolts holding the sprocket to the wheel. We chose to go up a size on the bolts from M5-M6 so hopefully it can withstand the torque.
The front seat bolt is tearing out from the torque, so we added a fender washer to hold it down.....along with lock washers on all three seat bolts.
The brakes are starting to squeak as they bed in. These new calipers have adjustment screws, but our spacers put them all the way in. We may shorten the spacers so we can get within the range of the caliper adjustment.
Finally, both kids (12yo Son and 16yo Daughter), are loving it so much that they are handling the fixes themselves. I was skeptical since I did 90% of the build work, but they definitely appreciate doing what it takes to keep it on the street (or the sidewalk in this case).
Oh, and the boy now says it is too slow. Contemplating buying a 2nd Predator and going full bore with cam, piston, flywheel, etc. Would love to get some sick RPM/speed out of it. Of course, changing the gearing would be lots easier.
