does any body have the wb rev box on there 400ex
i put mine on and tried to start it and it would in't start so i put the stock back on it and it started, i shut it off and put the wb back on then it started no problem, when it sits for a long period of time it won't start unless i have
it pulled to start it, it don't take much to start but it is a hasle. does any body else have this problem.

 

I have never had such a problem with my bike,maybe you have a faulty box?I have had my rev box for nearly one year.

 

I had same problem I have to put battery charger on mine after it sits over night but if I put stock box on it starts right up,, figure that one out!!

 

My buddy has been having same problem on his 99 400ex.It has been intermittent however.We checke d all connections and cleaned them.Didnt help.It does it when it wants to.It even has a tendency to blow fuses.never a problem with stock box but every now and then the WB unit acts up,wont start when cold and blows fuses when you hit starter button after being shut off when ridden hard for a while.He sent the box back for exchange and this one does same thing.I have yet to have a problem on my 00 400ex with the WB box.

 

well i called the guy i bought it from and he is sending me another one, he said he's had problems with previous boxs.

 

the mail just come got my other rev box, put it on it starts fine now, if your having problems
with yours take it back and don't let them
bull**** you, and tell you its suppose to do that or it's because you have mods done to the bike.
if you are looking to have motor work done call
pro fab atv (740)654-0734 its where i had mine done and it made a world of differnce.

99 426ex,11:1,web cam,k/n,dyno jet kit,6 air box vents,rev box,ids-2 super trapp pipe,14 tooth sprocket = lots of kick *** power

 

well i thought the problem was fixed but it's still doing the same thing. anybody that had this problem, what did you do to fix it?????

 

The stock 400ex does on or about 64mph. With an aftermarket rev. limiter just how much faster will it go. What mods do you have to do when putting on a new rev. limiter.

Thanks,
