That's a great bike, and the price is very fair. I was seriously considering one. I wound up building up my ZX 50 instead. 5k, and 82 mph but I havent riden it in close to a year. Just a few rides now, and then.
Rich's SR took about a year to build, and it wound up that every part had to be hand made. It is a turbo (Zenith I think). Every part was machined/fitted/tuned to his design. Right down to custom built injectors, and the software that runs the computer.
At one point we talked about me replicating all the body panels in CF for the bike but another 5k put that out of the ball park. Plus I couldn't travel to Texas for 3 weeks (seven mean ass dogs to take care of).
If you do go for the Ape, talk to Rich first. He may be able to help you out.
