No I didn't I am doing the swaop myself and I will be doing a writeup on how-to install the motor. Also I have been talking with Eric Gorr and I think I am now gonna go with the 285 kit instead. He said on take off the 285 will smoke the 310 and will only have about 2 hp less. Basically I am building this bike because my original tecate engine needs a waterpump cover bottom end rebuilt and is leaking coolant from a few different gaskets. And parts are nearly impossible to find. I want a newer motor with more parts availability and more power. Also I have lots of friends with the new 450r's and the YZF450. And all they tend to do is talk about what an old piece of *Edited**Edited**Edited**Edited* I ride. Simply because it has 3 wheels. So soon it will be fastest production quad verses fastest production trike.And we will see who's whining about what then.
