    Hey guys, newbie to the forum. Need some help with my 07 polaris hawkeye 300 4x4. Yes it's a no spark issue. Fun. But I think I've isolated the problem to the pickup coil.

    Polaris Sportsman
    Hi guys, I recently bought a 2003 SP 700 Twin. The previous owner had NGK BKR5E plugs installed last September. :hmmm: My question: Isn't this plug too "hot" for this machine? The specs say RC7YC plugs - the NGK equivalent would be BKR7E. What do you think? Should I replace the plugs to...

    I have a 2000 Magnum 500 that seems to only run for about 30 seconds whether idling or not. It's getting plenty of fuel and I'm thinking that it's loosing spark. It usually restarts after a brief wait but only for a short time.
