About two years ago I purchased two used Baja minibikes for my two sons and I to ride around.

Several months later, one engine started leaking oil from the gasket between the crankcase and the output shaft bearing end while one son just kept riding and riding and riding........

With Predator engines new at $99.00 I decided to purchase and install a new one since the bike itself showed signs of some high mileage use. The new Predator went in fairly smoothly and worked well with one exception-there was no charging coil to run the headlight. This was a major issue for my sons!

I kept the old engine and after over a year, I set one of my boys to scavenging parts from the old engine- a "Jae-dong" brand engine that did have a charging coil. Today, we pulled the predator engine apart and took a look under the flywheel and found tapped mounting bosses for the charging coil. The predator flywheel did not have magnets, however the Jae-dong flywheel was a match for the Predator flywheel, so we installed all the parts and tried it out.

Worked great!

It's pretty snappy as it is right now. In some ways, the bike tops out far too soon, but on the other hand, this is an offroad bike, so a high tip end isn't called for. I'd like to play with the gearing a little bit, maybe get another 5 mph or so out of it. Right now, it snaps up to top speed pretty quick, then while the motor still clearly has plenty of grunt, the governor cuts in and holds the rpms steady.
