400ex - bad cam?


Recommended Posts

Hey, im not sure if the cam is even screwed or not, I need to have it checked out.(there is a piece that seems to be a little loose near the cam sprocket) But the wheeler still ran like a bastard before I tore it down, so im not sure. But if the cam is bad, and I decide to buy a stage one or stage two hot cam, are there any other mods that have to be done to the quad to install the new hot cam, or can I put it in, set my timing, and be good to go?

Thanks

Just so you know. The XR400 cam will fit the 400EX. The stock XR400 cam is about the same as a Hot Cams stage 1. You do not need anything extra to install a stage 1 cam. Anything higher will probably require hardened rockers.

Thanks, not really sure if it needs replacing or not yet, the wheeler ran great before i tore it down(I dont even know how, one side of my piston was toast :P) ill have the cam checked out, thanks.

      I added more fresh gas it sat one day now, it's acting up again. Before cleaning out carburetor it wouldn't idle good and had gas leaks from carburetor. Now it idles pretty good but, if I increase throttle speed at a certain amount it starts missing bad. I'm going to try and post a short video. Just about ready to give up on this thing.😒  you can see reflection perking in video.

      Hello folks, my machine wound up with I think water in the tank etc. It runs but speeds up and slows back down randomly. When not running I don't see gas dripping  from the drain nipple on bottom of float bowl and drain screw is closed tight. With normal idle speed I see no leaking. When the idle speed increases quite a bit on it's own, gas appears to start slowly dripping from float bowl drain nipple? I'm wondering if the carb is flooding and the gas is actually coming from higher up and just appears, to be coming out of nipple but, is actually running down the sides of the nipple? I put a kit in the factory Mikuni carb last year after sitting for a while and I think the gas in the jug I used had drawn moisture. I plan to pull the carb tomorrow and clean everything out. I was just curious if anyone else thinks it's probably something in the carb and is, acutally a flooding problem? Thanks Folks! 🙂

      I am in the process of puting it back together after replacing the DPS gearbox.
      The manual I have states that it will need to be flashed by a dealer. Is this still true?
      Also , I have a mystery bolt That I cannot remember where it goes. M6x 70 or so.  Hex head with a flat washer.I will try to attach a pic.
      Pic is no go for now....Cox issue I will try again later
      TIA

      First issue was fuel pump wont start once ignition has been turned on. Replaced the pump as I had one on hand, than noticed no power so replaced the fuel pump relay as that was were i traced the power to. Still nothing so further inspection looks like signal is coming from the PCM (FLR B20) but not switching the the brown wire to the fuel pump. Ive checked the operation of the bank angle sensor and it appears operational. Fuses and wiring all appear OK. The engine stop relay also tests OK. Ive been through the repair manual and diagrams but to no avail. Fully stumped, any tips would be helpful. Thanks
