[ebo 4356]

I've heard rev boxes dont let your engine last as long is that true and should i get one.

YEA ITS TRUE IF UR GOIN 2 HOLD UR QUAD WIDE OPEN PINNED IN 5TH GEAR. ALL THEY DO IS ADV TIMEING AN GET RID OF THE STOCK REV LIMIT IT RAISES THE RPMS 800-1000 RPMS I BELIVE DEPENDIN ON WHAT BRAND. SUM R ADJ HAVE DIFFERENT SETTING BUT THOSE R A FEW HUNDRED BUCKS. IT GIVES U BETTER THROTTLE RESPONSE AN MORE RPMS ID GET 1 IM SELLIN A BRAND NEW DYNATEK ONE FOR 80 SHIPPED SELLS FOR 94.99 NEVER BEN OUT OF THE PACKAGE

Depending on which one you get, it advances your timing and allows your motor to rev higher.

If your looking for a CDI, Procom Magnum, Dyna Tek, Sparks CDI or Team Alba, there all good.

Just don't get white brothers.

I thought I read on here a while back that heavy duty valve springs would help with reliability but are not necessary. From what I remember- with an increased rev limit, you increase the chance of floating a valve. I put on hd springs when I did my build to be on the safe side.

why r u saying WB's r junk i have one on mine (was on it when i got it) and i have had no probs. im just wondering cuz if they r jusnk i will get a new one.

[81 clark racing]

they short out then ur f***** if your out riding also cause problems starting when hot an cold i had just problems in the cold

[exrider008]

thats odd my starts right up hot or cold.

The WB revboxes are really just a Honda XR250 stock revbox. They need a really strong battery to spin the motor over fast enough to get the ignition to spark. When you kick the XR over with the kickstarter, you spin the motor a lot faster. That is why some people have trouble with them and others don't. 81 clark racing is a post whore. Dude, we get it, you have a revbox for sale. Put it in the for sale section.

[81 clark racing]

rummerd- if ur stupid *** would look in the for sale section i did if ur tired of seeing it posted then why dont you buy it? didnt see any rules about postimg to much

[400ex7]

If your willing to fork out the money the Vortex is good I run it on my 400. It has ten different timing curves you can switch to. It works very well, but I paid like 370.00 for mine.

[rummerd]

Just once I would like to meet an internet tough guy face to face. Some people's kids.

[81 clark racing]

an interent tough guy. yea ur self "meet face 2 face" no ones being one but you. ur crying over nothing. posting 2 much get a life. if your sick of seeing it then dont read the rev box threads. and stop posting your lil crying messages no one really cares how u feel and what u think.

[rummerd]

typical response. some people's kids.

[400eXr1d3rZ]

81 clark racing, you really need to be more mature about this.

Come on, im 13 years old and im posting like a mature person.

[QuadJunkies]

I'm interested in this, can you let me know where you purchased your Vortex one from?

[NY06400EX]

I have a list of mods I intend on doing in the very near future and the rev box was one I was contemplating. I'd like to read up on some info from the different manufacturers etc.

[QuadJunkies]

ask anyone whos ran a GT Thunder box and they will tell you they are a great box Im sure! ;)
