Motor Heads,
I just purchased a EC40P 398cc twin with dual mikuni carbs. This ,so I'm told , was plucked out of a 68-71 Mustang. She appears to be fan cooled. Will this motor survive the summer powering my old 6 wheel ATV??? What kind of HP will this old girl put out?? Thanks for any info you can pass along!!! Dano

Yes, it should survive in the summer if it is fan cooled and he loads are not too high. You may need to rejet it so it gets the proper amount of fuel. Horsepower output on that I am guessing is in the 30 to 40 hp range. I have a colt 295 on our go-kart and it has been working well in the summer.

  5. What is this in my gas tank?

    General
    Hello there! New forum user and new snowmobile owner here. I've bought 1998 Polaris Trail Touring.

  6. Runs good cold, bogs/dies when warm

    General
    I have a 2004 Polaris 600 RMK vertical edge. Ran it for the past 2 winters with no problems. Recently it starts fine but then after about 10 - 15 minutes of riding it loses power, bogs down and dies. It will restart right after it dies, if I let it sit for a few mins and runs fine for a few...
