Ok thank you Snowflake and Osssagp. Do you know how much it will cost for a suspension re valve? Also Ossagp. I'm new to having a nice bike to ride haha. When I was much younger I had a 50cc Yamaha. When I was either 11 or 12 I got a Honda XR80. Had it for a few years and then sold it. It was pretty must the biggest piece of junk but it was rideable and started everytime on the first kick. I really pushed that bike past it's limits. I also did a lot of riding on my uncles Yamaha 450. Then just a few weeks ago I went out and bought a brand new dirt bike. I'm not new to riding and can ride very well. Just new to wanting to maintain, upgrade, take care and just learn more about my bike. I never changed the oil or anything on my 80. Didn't really realize I had to though at that point. Anyways, now that I have this new bike I want to take excellent care of it and upgrade it. Don't get me wrong, I can change the oil and do basic maintenance on my bike. And when I got the bike the guy that sold it to me went over the bike and everything with me.
I am thinking you might have been better off buying a KTM 150 or 250sx instead of the CRF250 four stroke. One thing for sure is if you bought a 150sx or 250sx. You would not want or need to upgrade anything for a while. As far as power and motor work goes.
