Fastest YFZ
I don't own a YFZ, but the fastest one I have seen was at Little Sahara, OK. It was built by Phil's Cycle in El Reno, OK. Curtis Sparks portwork, FCR carb (size=???), alcohol, stroker crank, 14.1 piston, Sparks cams, Sparks exhaust, extended swingarm...........................That's all the info I could pry out of them. It's a really fast bike, seemed very responsive. About another 8 bike lenghts or so and he could have caught the old QuadZilla..................[img]i/expressions/face-icon-small-wink.gif[/img]

This is all good stuff! Thanks. It looks like after the exhaust, airbox, airfilter and then jetting is a cam mod. Does this mean "retarding" the cam or something totally different? I got some great info on an earlier post on "retarding" the cam I just want to make sure. I have also read a lot of posts that talk about a larger front sprocket?? What does this do for the bike? A different sprocket would just give you torque in a different part of the powerband correct?? This does nothing for more power or am I wrong? What size sprocket is good for most speed? What is a good brand?
On that last post: I ride at St. Joe a lot and I do not see a whole lot of fast YFZ's. However being a little bit newer to the sport I tend to not race a whole lot of people unless asked or it's someone I know. I see a lot of Banshees and a fair amount of Raptors, but almost all of the YFZ's are pretty bone stock.

The ESR intake is a formed aluminum piece that sits between the carb and filter . heres a link to the site http://www.esr250.com/default.asp
It removes the restrictive plastic intake that is stock and comes with a K&n Style filter
