  1. I am in need of some info on the '02 CRF450R engine. I race Go-karts and currently run a KX250F and I am now building a 450. In my manual for the KX it tells me were the peak torque and peak Horsepower along with their values at the give RPM. I need this RPM value for the peak torque and the peak horsepower. Also, what RPM is the rezv limiter? I need all this info for setting up the kart gear ratio for different tracks. Any help about were I can get this kind of info I would appreciate it. Thanks, T.J.
  2. Has any body converted a KX250F or similar to methanol? I race in Open Oval karts and have a KX250F engine bolted on it. Runs good but the competition is getting tight so I am looking to switch the methanol to get a quick change. If anyone has done this change or nows of anyone that will do it, please let me know. Thanks, T.J.

    Thanks guys. No I dont shift it. the track we are on isn't long enough to need to shift. Our track is a 1/7 mile dirt oval. This thing has so much torque and top end power that all I use is fifth gear and just a little clutch on the starts. If I go race on some bigger tracks I will set it up to shift. The clutch works perfect by the steering wheel. There is not enough room for another foot pedal. T.J.

    Here are some pics of my 250F ride. I did'nt think two wheels was enough so I went to four. It is a Kawasaki. http://karting.4cycle.com/gallery/showphoto.php?photo=1233&size=big&cat=500&ppuser=6311 http://karting.4cycle.com/gallery/showphoto.php?photo=1234&size=big&cat=500&ppuser=6311 http://karting.4cycle.com/gallery/showphoto.php?photo=1236&size=big&cat=500&ppuser=6311 It's a blast to drive and race. I have been racing it all season and just recently I got it hooked up to the track to win a couple races. Enjoy, T.J.

    2003 Yzf250 Tranny Problem???

    If you decide to replace the engine because of the expense of rebuilding the tranny, let me know, I will buy the motor off of you. I need an engine to modify for a Kart. T.J.

    YZ250F Engine wanted!

    I have not decided yet. Ignition side would be easy or with a little more modifications I could attach it to the water pump side of the crank, not the water pump directly. I dont want to run off or the clutch basket gear because it is a reduced gear. I dont want to mess with that. I want direct power. Thanks for the reply, T.J.
  11. Looking for blown, damaged, or wore out 250f engine. I am looking at doing some seriouse modifications to one to put on a racing kart. I will be doing alot of machining and R&D work to it to completely remove the transmission. That is why I dont need a good engine because It might not work and dont want to be out too much money. If my mods work, then I will get the engine running. If anyone could help me out, please let me know. Thanks, T.J.
