aftermarket rev box

28 posts in this topic

ok so ive been talkin to some ppl with these rev boxs and they say its a quick, easy, and worth buying upgrade.

heres the one im thinkin about buyin...

eBay Motors: AMR STAGE 2 REV BOX HONDA TRX 400EX IGNITION 400 CDI (item 370064886695 end time Aug-28-08 16:57:54 PDT)

i was talkin to my buddy about it and he said it would eventually blow the engine(i kno bullshitt right?). i said i wouldnt think so, unless i held it wide open for a prolonged amount of time. but my question is, could this rev box possibly blow my engine? im tryin to make my quad as fast as possible without taking away the 400ex's well known reliability.

and another question wat stage should i get? stage 2 or 3? remeber my quad is stock

thanks alot guys

No, it won't. If you get the stage 3, possibly. Just for comparison, On the Rhino the stage 2 increases from the stock 6800RPMs to 7800RPMs. The Stage 3 raises it to 9000. With stock internals you that is too high of reving. The stage 2 SHOULDN'T give you any problems. Stage 3 is for people that have crazy after markets done inside.

I have a big gun Rev Box in my raptor. Ya it does a fair amount of pep to your ride. Ya its quick and easy to install. It took me about 10 seconds to install, make sure that yours is reaady to snap in and you don't have to mess with any wires unless you are comfortable with that kind of stuff...

Good advise, most of the CDI boxes are plug and play.

      Hi All,
      Has anyone found engine oil in their air filter box. The must be little or no baffle between crankcase ventilation and that hose that attaches to the air filter box.
      I went to pick up my ATV today 60 miles away that they could not fix the jerky low speeds on and before I loaded it decided to check on this. Sure enough there was a good coating of oil with some pooling in the bottom of the air filter box. The air filter has oil on it too but is it a dry element or oiled element type. My guess from the color of it dry.
      I heard on a comment on my YT videos that there is a kit for this issue? Is this a CFMOTO fix?
      Thanks
      Kevin

      after working great all weekend today my big bear 400 wont start. I noticed a strong gas smell, took cover off air box and found 2 inches of gas in the box. I figure this has to be a carb problem but hoping someone can pinpoint exactly what to look for/replace. thanks!

      Exploiting a loop hole in the law, turn 4 wheeler into rev trike
      for a long while I have been trying to get a real 4 wheeler street legal.
      the problem is with the state laws, if it has 4 wheels, its a car and has mega more rules.
      If it only has 3 wheels, its a trike and can be made from cobbled junk parts held together with duct tape and they will plate it
      I wonder if anyone would have insight on changing a 4 wheeler over to a single rear wheel?
      [ I can't afford some $40-60,000 canam or super bike modded into a car, rev trike kit ]
      I want something I can truly ride year round on and off road. Ive rode enough old Honda 3 wheelers that I know I do not want a traditional motorcycle trike. So the single wheel has to go out back.

      Has anyone bypassed the rev limiter button on the 550 Grizzly. Since I have put tracks on the quad, I need to run it at higher rpms in 4X4 in the deep snow. Is there any downside to bypassing the switch or even installing a 2nd bypass toggle switch?
