My name says it all. I have a '03 Honda Sporttrax 400EX with a new aftermarket carb on it that seems to be having issues. I can start it but it idles really rough and when I give it throttle it just kills the engine. I have tried adjusting the idle screw but to no avail. I am in the San Diego Ca area.
Any advice will be greatly appreciated. I would also like to get an owners manual for the thing too but can't seem to find a downloadable one.

Hi quad is up and running now, starts fine, revs and ticks over fine but when riding its bogging a bit. If your sat with engine running its fine but when you set off your having to rev it very slowly to go otherwise it drops its revs. And i mean very slowly, try rev normally and revs just drop off then when your going its bogging slightly. I have tried adjusting air screw but doesn't seem to make a difference. Any ideas. Seems like an air problem but not sure.

Hi, I have been around everything with a motor since I was little, and finally purchased more to get my husband, and kids involved. I have 4 quads I will be searching around for information on. I have two 2002 Suzuki LT80K quads, a 1997 Yamaha Timberwolf 250, and a 1996 Kawasaki Bayou 220. I have had different ones throughout the years, and plan on buying another Yamaha Banshee. I plan on trying to learn more about all of them, so I can customize some of them. I know nothing about them besides how to race them, my dad always took care of the rest, but figured it was time for me to learn.

Hi guys, so Im i cam across this pretty nice quad. Its a 2003 400ex. Its priced at a little over $1,000. The seller states that it was previously rebuilt and has a hot cam in it. However, it is not firing. He says that it turns over and has spark. He also redid the wiring harness and still couldnt get it to run. I have some experience with quads from previously owning one.
My thoughts are its either something witht he wiring harness(cdi, kill switch...) or it isnt getting the right amount of fuel(needs carb rebuilt) or it's the valves. Or could it be timing? What do you guys think? Let me know!

I have attached a video so you guys can see how it sounds like. I feel like it wants to start but is missing something...
