I have spent over a year reading the posts on this forum prior to buying a Dirt bike. It takes a long time for me to make my mind up, and all the bikes on the market these days i can't believe all the bikes! Well due to the fact i knew i wanted a 4 stroke and something i could street also helped a lot. But this site has helped me so much i had to thank everyone for all the posts on here. I ended up with an o4 xr 650 r it's been licensed for street in California which took an act of God also been uncorked and just put the quicksilver pumper on which is killer!! that thang is great. Anyway Thanks everyone even and i am still looking for that post RE: taking the smog off ie the thang on the right side of the rad and hoses. Have a great one i feel like i owe you guys lunch or something. RIDE FAST RIDE SAFE.
