Hey!
I just bought a brand new left over 2009 YZ250F. I have about 20 hours now (trail ridden), I got a Yoshimura RS-4 slip on about 5 hours ago and it ran about the same as stock. I rode it once on a colder than usual day and the top end power wasn't there like it was on a warm day. I assumed it was just the temperature affecting it, but the next weekend I went riding and it was warm out. The top end power still wasn't there, it bogs and doesn't pull like it use to at 3/4 plus throttle.
Please help!
Thanks
