Hi guys ,looking for some input on running issues with 09 nytro mtx with mcx 240 kit, the sled has been turboed since new . the first 2 years the sled ran flawless , I sold it to a friend and he has had nothing but trouble, the problem he is having seems to be with the mcx box that fires the boost injectors, the trouble started last fall, when you would try to ride it would hit about 2 pounds boost and just sputter so we checked everything ,tried blowing in the line to the control box and seemed fixed for a while, have a couple rides where it hardly works so we take the box to the dealer, and they say mcx box is shot. My friend then buys a new box for 800.00 go out once and sled acts the same so back to the dealer,this time with the sled. dealer has the sled for a day they say its fixed but they dont know what was wrong, they say they put dyelectric grease on connections but couldn't make it act up . Surprisingly the sled runs fine the next few rides out, which also bring last riding season to a close. Anyway here we are again this year, first ride out the boost injectors don't fire, blow in the box and it works all day. second ride out it works fine , third ride out spend most of the day messin around again? any help or suggestions pleeeeeease this is getting frusterating:noidea:
