So I need to rebuild my 400ex (long story short Pistons and heads are completely damaged) and decided that if I’m going to spend the money and time to do it might as well bore it out. I decided to go with the 426cc seemed best for the type of riding I’m going to do. Any help or suggestions on what else is recommended or needed if I’m going to bore out? For ex. Do I need to get a better crank or clutch?I’m going to get the hd studs just to be on the safe side. Thanks for any help

hey guys new to the forum and new to the atv scene, I picked up a 2002 400ex, its completely stock except for the guy removed the lid, I picked up a white brothers e series muffler today, put it on and drove it, seemed to drive fine but I know a lot of people say to jet the carb if you put a pipe and a lid.. just curious on what I should put in, its still stock jets but I do have a 40 and a 155 that was given to me. will those be ok? i still have the spark arrestor in, i was reading that taking the spark arrestor out could actually make you lose power?

Hey guys I own a 2002 400ex and when I was cleaning the carb I accidentally broke one of the ears that hold the pin for the float bowl 🙁 so I went to eBay and bought a factory take off carb off of a 2002 400ex only problem is that the one I bought only has one vent on the side and the one that came on my quad has 2 vents on the side.. Everything else looks the same, Anyone know why that is and if it’s ok to use?

I have a 2008 400ex that I bored and stroked to a 460 and now the head gasket is leaking after about 20-30 hrs on it. I’m guessing the head studs started to pull out.. I just ordered GT Thunder HD studs and going to put them in. Any other suggestions as to why the head gasket would be leaking?

How hard is it to switch an es to a manual shift. Just seeing if it’s worth it or it’s going to cost an arm and leg. What’s all involved in the process.

What is the suggested jet for following setup?

2008 TRX400ex

-HMF competion exhaust
-K&N air filter (open air box)
-Elevation: about 2400

Looks like most jet kits range from the 150s to 190s…..

Even an estimate as to where to start would be great. Picking the bike up tomorrow and have the exhaust in the mail.

Thanks in advance!
