Rev box???

[patches85]

I came up with a rev box for a 400ex. It says "Shindengen" on it. It is supposed to be a white brothers. Can anyone confirm it for me. No other markings on it!?

If it is a White brothers, get rid of it, you will end up hating it, everyone else does...

Its smaller in length than the stock one. My quad is a 2000.

All that WB does is buy someones elses box and and put it in there own plastic bag and charge you some more money. Most likely it is a WB one if it is smaller. What is wrong with there CDI box is that during cold weather it makes the 400 harder to start. All that they are doing is giving you a box that is for an xr400. The box works great after you get the 400 started the 1st time that day.

the WB box sucked.. dont get it, it made my quad slower for some reason.. save up your money and get a real rev box, not a rip off of another bike

I got a white bros revbox.. It works great for me and starting is fine. But I haven't started it below like 25 degrees.

Does it say anything on it?

it is not for the xr400 it is for the xr250...there is a circuit that prevents the spark plug from firing if the rpms do not reach a cetain amount...the 400ex starting rpmm's are slightly above that so if you throw ina weak battery and /or some comd weather to thicken up the oil and slow the internals down...you do not reach that minimum rpm level and the spark plug does not fire...no spark=no start

yeah you got the whitebros box... thats what mine said on it.
