hey, i have an 04RM250 that has about 40 minutes on it.. when i push the kick start down slowly, i can hear an air sound on the first few inches of travel.. what is it? ive got a new cylinder on it (with no crack) and it runs simply amazing.. the dealer said it was the intake (i believe) and is completely normal... i want to believe them but im not sure if they just wanted to get rid of me or not? bike starts first kick easily.. thanks dan

After my porting I noticed an increased 'suction' noise coming from the intake...I would believe this is normal but knowing for sure may warrant further inspection. Good luck.

Take the seat off then start the bike. If it's intake noise, it'll get louder and you'll definitely be able to tell if it's coming from the airbox.

didnt you say in your other post that you found a crack in your cylinder and dealer replaced? was that not the problem after all?

My YZ makes a very pronounced noise when you cycle it over.
