[QUOTE="davidd, post: 91202, member: 1177"] Alp's designs are quite novel. The Amal carbs have no floats. In fact, the bike runs on Hilborn fuel injectors in the ports. The carbs at that point are simply throttles. There are jets in the carb and Alp hooks up some QD lines to supply it with methanol to start. Once started and warmed a bit, he switches to nitro and takes off. The oil is total loss. He runs it through the engine once and it is scavenged into a waste tank. Nitro engines do not last very long because of the high percentage of fuel pushed into the oil. Alp uses this to cool the engine also as the front of the bike is closed off to air. SCTA had to approve the front fender because there was some question as to whether or not it was a dustbin fairing according to the rules. SCTA ruled it was not. What is unique about the fender is that there is no gap between it and the fairing. When you turn the fork the fender distorts outward, and then returns to its usual position when going straight. Alp had several wobbles, but they were caused by the ruts across the course. He is not worried about it. He said had he known the course would be so rough he would have designed rear suspension. He will also soften the fork! David [/QUOTE]
