We just had our delivered from Sand Highway and it is sweet. I was not even aware of the upgrades and the seatas are sweet. If they were not for the double kart I would put them in my truck!! See ya at the dunes!

The white brothers exhaust does fit....I just installed mine a few days ago! What a difference!!!

Previously only the fronts were adjustable and now the rear shocks are as well. Yep the White brothers pipe fits. The carb jets are already bigger so there is no need to change those. The battery is now mounted up on the swing arm so there is no need to reposition it when adding the White Bros pipe.

My Hammerhead Twister ran pretty good for about a week. But now it is doggy slow. I thought it would get better after break in but who knows. I took it very easy for about 5 hours to make sure break in was easy on it. Also I just saw the 2005 Dazon two seater 150 and they look killer but they were not yet available when I bought mine. So I guess it will just be for the kids to putt around in. Not enough performance for me to have fun. I weigh 185 lbs. I don't plan on spending the extra for performance parts because i don't see it getting fast enough for an adult and no way would it be good in the dunes. Nothing has really broken though just doggy.

Carlos,

Yes we have put a Honda 400 in a single seater. Check it out here http://sandhighway.com/videos.html

It's sick but a little scary. The bike would haul ass at freeway speeds so this kart is going to fly. We are still working out kinks on the rear suspension but everything else was done with minor fabrication. We borrowed many parts from the street bike donor.

Jack,

Yes the battery is usually shipped separately.

As for the hop up, if you put it on before break in just take it easy for a while. The kit will put a little extra stress on the motor but if you are easy on it for 5 hours or so it will be fine. Just don't run it at full throttle or for long periods of time. Remember to drop the oil after break in.

The lower hose connects to the vaccum and the upper hose to the carb.The device on the bottom of the tank is a vaccum fuel pump.

Adjust the air gas mixture by turning the screw on the side of the carb.. Also make sure all ignition wires and plug wires are tight.

In dealing with bikes and buggys in the past, most engines are jetted for their set-up. The dazon's are jetted from the factory for the pipe and breather that came with it. These buggys pull a massive amount of air without mods to the breather and pipe .Thats how they get their power.You've heard the saying "the more flow, the more go" and that is only increased with the addition of the pipe and filter. The slow jet in the carb cannot supply enough fuel at idle to support the engine.Even at stock, i've found that these machines don't like to idle very long.

    Have you ever had it to die while in the throttle or just while it is idling?

  I really think the upgrades for these are a good idea, but all of these increase the amount of air-flow tothe engine. There are jets available also but they would in my opinion be about the right size for running about 3000 feet above sea level where the air is then, thus needing less fuel. I would suggest as an experiment, tapeing up about half your air filter and see what happens. If it helps, youre running too lean for pipe and breather. If it makes it worse, you are amazingly too rich.

 The only way to fix a lean condition is either restrict the air flow a little like with the tape, or have your jets boared a little unless there are several different sizes in the aftermarket to experiment with. If youre rich, you either need to jet down, or allow even more air in with the screw and maybe some manifold mods like or even a breather with even more flow.

  Sounds like youre lean to me though.

Sorry so long

Your idle mixture to 1/4 throttle is all that is controlled by the air screw adjustments.The main jet circuits are located inside the float bowl. These must be unscrewed and removed, then replaced with other sizes.

  Still say your running lean. Try the test with the tape and breather. This will hurt top end but will tell you if its lean on the idle. I think I read where these karts have a manual choke. If so the same can to a certain degree, be accomplished by pulling your choke out about 1/4 to 1/2 and see how this affects engine. If engine speeds up a little, your too lean. If it sputters and dies, your rich. This can also be used to check top-end jetting. If it helps,your lean. If it hurts, your rich or o.k.
