Hey guys, I've seen alot of problems with the Copperhead CDI's on other posts, but all problems were mud/water related. I have an '07 brute 750 and I am just returning my 2nd copperhead with NO mud or water riding strictly trails and both have crapped out on me in the middle of a good day of running. luckily I carried the stock box and the blue beast fired right up after plugging it back in. am I just really unlucky or has anyone else had the same misfortune? very aggravating..I told them there will be no 3rd box please give me a full refund.
