white bros. revbox

Just wondering if these are worth it and do they do as advertised. Thanks guys!

You don't need a rev box for a mildly modded motor. By the time your bike rev's out, I't's done making power. Best advice I can say is take it out in 3rd,4th,5th and rev it to the limiter and see if it pulls hard till the limiter. If it falls off, no need to buy one.Also, If your battery isn't fully charged, The bike won't turn over.

They do as advertised. They increase your revs and change your ignition curve.... Problem with the white brothers box, big gun, sparks, etc, is that they are simply 250X IGNITION BOXES!!! Thats right, its the same curve as a 250x... You will get some better performance, but you will be hating your life trying to get your bike started, especially if you have added compression or mods to it... Save up some money and get a GT Thunder, or TC rev box, those do NOT make the bike start hard, and have better performance than the white brothers box. This is coming from someone who used to use the WB box and changed to the TC, the best decision of my life!!!!
