How do you add a UNI filter to a GY6 helix or carbide?
This has been asked a few times so I thought I would start a quickie thread on it.
Look at the pic below. That is a complete setup for a helix or a carbide. It would likely work on any GY6 but the variable comes in when deciding how to connect the carb to the UNI. You can't connect it directly because the frame bar would interfere. What you do is go to lowes or home depot and get a piece of drain. This same kind of drain used for your kitchen sink so find the plumbing section. You need the drain pipe, a rubber coupler, and a hose clamp. Take the UNI with you so you can get the correct size pipe (I think it is 1.5 inches). Once you have the right size pipe, get a rubber coupler (that's the grey piece on the right side of the drain pipe in the pic). It connects from the pipe to your carb. It will be found in the same section as the drain pipe. Then get one hose clamp. It connects the rubber coupler to the pipe and you use your stock hose clamp to connect to the carb. The only thing you have to do otherwise is measure how far out you need the UNI to come out to clear the frame and you cut the drain pipe to that length and bolt it all together.  See this thread for how to rejet your carb: http://www.buggymasters.com/forum/showthread.php?t=168

I dont no about the Helix but on the Carbide I was able to disconnect the stock air tube from the air box and put a Uni filter on the end of the tube.Made a huge difference,put in a 136 main jet to.Total for upgrade 20.00.

does the 136 work like you never changed it or does it stall and stuff..?

The 136 works great good plug burn.Does seem not as spunky from a dead stop take off,but gained 4 mph on over all speed.Ordered a iratium plug hopeing to bring the low end spunk back.Over all am very pleased with the 136 main jet.Tried a 132.5 and keep the quick take offs but the plug color looked alittle hot.

This thread shows what I did for mine with the specific parts I got.
http://buggymasters.com/forum/showthread.php?t=6404 Currently im running the full 12 inch drain pipe because it puts the uni filter out to where it rests on the back crossbar for support. Planning to shorten it to 7 or 8 inches once I get a support bracket for the drain pipe figured out.
