  1. Im usually close to my gas tank and i usually only run threw a half a tank already. Dont get to ride much. Ya i was looking for that bottom end cus my buddies polaris predator was killing me off the line and out of the corners. I just put on some +1+3 arms works front shocks and tusk wide hubs so those should help catch em in the corners too. I kept going up on two wheels in the turns with stock setup.

     

    If these pro circuits seem to choke it up like im reading then i might see if i can grab some R2's.... Thoughts? Second choice is CPI's. (i have no experiance in either, just what i have read)

  2. 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.

  3. give us a ride report when you get a chance, there is a possibility that it wil be difficult to get both sides tuned right, as in one side prefers slightly

    different jetting to the other

     

    so you would push towards getting one side on the money and the other side rich as opposed to one side on the money and the other side lean... if that makes

    sense

    I see what your saying, better to clog one side up slowly than burn it up quickly, right? Surprisingly enough besides changing the needles and jets i havent tuned anything else on the carb and it started rite up and idled perfect. There is to much talking and not enough riding rite now to give a full report. Live in the city and watch my baby girl all day. If it gernades ill be on the wanted list for some ported jugs. If this cool head deal falls threw, ill need one of those soon.
  4. So again, you just started hacking away without any knowledge of what you was going and any plan on what you wanted to do?

    Zilla, again i did lots of research on it. If u read this thread i have said many times what im aiming for and even in particular what a couple of the things i did to improve towards that. I dont suggest messing with the exhaust hieght unless u r a pro though as it is advised all over the internet. The intake windows u just want big and no sudden angles leaving it a rough surface so that air/fuel mixture wont stick to the surface. The transfer ports are angled a certain way so u want to taper towards that not make them as big as possible. The boost ports like i mentioned before help bottom end but make em too big and you have to rienforce the outside with jb weld or welding it. Just cleaning up the casting flaws alone is supposed to help a lot, even a brand new engine.
