i just jetting my 250 a few days ago and now im starting to hear a pinging in the motor, my friend said it might be the valve, but im not sure? could someone please tell how to stop this. thanks alot atv connection forum!

 

My 2003 Foreman 450 started making a pinging noise at 20 hours, I brought it to the dealer, they adjusted the valves, clutch, tightened every bolt they could find and it still made the noise. They went upstairs took a brand new one off the showroom floor and it did the same thing so they said it was probably just the cold dense air maing it run lean and ping. I already bought a 150 main and and IDSX exhaust for it so I will install those and see if it goes away.

 

it sounds like you need a valve adjustment...........


both my ex's did the same thing

 

thanks i will bring it to my local dealer and have them adjust the valves but is it alright to ride it this weekend with my buddies and then take it up to the dealer on monday, or is that going to hurt it?

 

it shouldn't hurt it to ride a little while
