Has anyone else had their WB rev box go out on them? mine went about a month ago. I left it in the garage over night, went out the next day, and the thing wouldn't fire. so i checked every thing out on it and tried to start it again, nothing. For some reason i thought i'd put the stock cdi back in it and give it a try. It fired right up. So i let it warm up, shut it off, and put the WB cdi back in. It fired right up! So i left the WB cdi in it and rode it all day with no problems at all. The next morning i go out to the garage and hop on my 400ex, hit the start button, it turns over, but it won't fire again. So now i've had the stock cdi on ever since. Who else makes a high rev cdi box for the 400ex?

 

Curtis Sparks makes one at www.sparksracing.com They got some new stuff..

 

mine does the same thing but dont no why?????????

 

I GOT ONE TOO..BUT HAVE YET TO HAVE ANY TROUBLE, BUT I HAVE HEARD OF ALOT OF PEOPLE HAVING TROUBLE

 

same here... exact same problem

 

anyone having these same problems with a different brand or a XR250 cdi box? i need to get another, but don't want the WB cdi again. Without the higher rpms, i'm constantly hitting the rev-limiter.

 

I know someone with the XR250 cdi and it works fine. It also has the same part number as the one from WB at half the cost. WB is ripping you guys off.

I have the XR250 rev box. I never have any problems with it. Save some money and buy it.

 

Watch it with these rev boxes guys. Everybody at the local shops tell me NOT to put one on unless I've done motor work. They say you'll float your valves and put alot of extra stress on the rod. I'll stick to the stock one for now.
I'm just trying to warn you. I don't want to hear of someone blowing their motor because of this. I know Hondas are durable but every motor has it's limits.
