Sooo, how do u guys like your Serval's??? I know this is an old thread but im building a serval and saw couple of you were in the process of biulding sevral's years ago and someone kept saying, "once they are out for a while then more will be known" or something like that. Well share the knowledge. Im rebiulding my 91 into one now. Putting 35.5 big bowl mikuni flatslides on it, trued and weld stock crank stock stroke, fast head with 19cc domes(running half 91 half c12 klotz 40:1) getting pro mod done to tranny and heavier springs put on stock clutch. And putting on a pair of pro circuits. I see in the thread a lot of ppl looked down on the trail pipe and would like to hear a later input on it. I will be dynoing this quad after its done in a week or so.
