Xtreme Typhoon 125
 

My son has a Xtreme Typhoon 125. Trying to fix one of the many problems with this quad. The throttle repsonse is bad. I shortened the spring down at the carb. helped, but is still stiffer than the trottle on my Z400. I read somewhere that this is a Dirt bike carb. They also changed the throttle assembly to a metal unit and to replace it with the older style throttle assembly. I can not find a website for this company. Anybody know their website, or where I can get this assembly?? Was thinking about just replacing the carb with a better carb. Any info would be great. What size/brand is this carb?

Hummm, I google your quad and get a bunch of sites for parts, etc. :huh:

Maybe give it another shot?

The question I would have is whether this is an actual Xtreme brand, or one they sold at Pep Boys and a few other places. Huge difference in the two.

Try taking the return spring out of the thumb throttle it's very stiff. The extreme and pepboys are the exact same thing except the Xtreme has a frame brace on the bottom between the front subframe assembly and the swingarm pivot. Don't believe me go look at a pepboys or baja brand name bike and they have Xtreme and a serial number engraved on the front of the frame. Xtreme went out of business in 09. Whenever I needed parts I usually found them on amazon or used pitbike parts since they are the same thing except for a front subframe assembly bolted onto the front of it instead of forks.

711Streetfighter,

have you replaced the throttle or carb yet on the Xtreme??

The two extreme models I saw weren't even close to being the same.
