rev. box

[One_Bad_400]

hey i am thinking about buying a rev box but I have a few questions first. The best place I've found is http://www.magicracing.com/myProducts.cfm?CFID=682841&CFTOKEN=3398396&CategoryID=286 for only 90 bucks and it raises the limit 1500 rpms. is this the best one, for the best price? what does installation require? will I need anything else? well it need to be re-jetted? any useful info appreciated, thanx

I'm pretty sure it's a plug and play deal but I could be wrong.

well I bought it, two day shipping, so I got two days for ya'll to tell me any problems I may run into....

The rev box is just plug and play. It's the little black box on the front of your bike. I found that my bike almost double on the gears and i have a 1500 RPM. As for rejetting no you don't have too. It should run great with just plugging in the box.

That is the box that I have and it works well.

That rev box isn't the WB box right??

They could all be the same box just with a different name

no not all boxes are the same with just different names. some have different internals than others. i cant wait to get my sparks box put on and try it out. will let you guys know after the weekend

i thought they were xr 250 boxes:confused:

i thought they were based off of the xr 400, but i don't know. some say that they also change the spark curves of the bike. big gun claims that theirs makes a full two horsepower over stock and they showed theirs compared to the white brothers on a dyno and it made more power. however, with big gun making the dyno, of course its going to make more power. i don't know what bikes they were put on though.

i installed and runs good ill i had to do is plug it in and go

[mx400]

all boxes are based off of the xr 400 box yes. but companies modify the internals on them so they get what they want and so each box is a little different.

dragged the Z a lot today, makes a big difference not having to shift so soon, I like it

[4wheelboy]

think i should get one for the xr?:confused:

Dude buy a XR box it's the same thing. Dont let anyone BS you abot a white Bros. there the same thing. I've ran both and their is no difference. So save yor money, just me 2cents

[One_Bad_400]

do ya'll think it will ever cause problems? the rev limiter was obviously there for a reason so will it cause problems bumping it up that much?
