    2006 CRF 70 Jetting

    Usually on a big bore set up you would jump 1-2 sizes bigger on the main jet, move the clip down one position on the needle, and back the pilot screw out 1/2 turn. This should get you in the ball park. A little fine tuning may be required.

  3. The way it sounds your not mixing your gas to rich. Either it is your coil isn't hot enough or you need to run a heat range hotter spark plug.

    How long has it been since you put a new spark plug in the bike? Some times the plug can load up and not clean out until you crack it wide open. If that doesn't change anything try moving clip to 2nd position. That will lean it a little in the mid range rpms. Sounds like its running rich in the mid rpms.

    Raw fuel coming out of the pipe indicates a rich situation, not a lean situation. Try turning your fuel screw in 1/4-1/2 turn and see what happens.

    ohlins shocks... any good??

    Ohlin shocks are very good shocks. Myself, and friends, have had very good luck with Works shocks W/ rez. Very affordable and easy to install!

    Usually at higher altitudes the air is a bit thinner so you have to lean the carb a bit for the bike to run right. kmurray is right, trial and error. But you will have to go to smaller mj for it to run correct.

    CRF230 Idling Problems.

    Do you have problems getting the bike started once it is hot?

    CRF230 Idling Problems.

    What is the stock pilot jet size? Barton is right, usually a hanging idle is caused from a lean condition in the pilot circuit.
  10. From what I've read on this jetting forum, a person should drain that VP racing fuel from the bowl after your done riding. Other than that have done a spark plug check to see how rich you actually are. A 188mj for a 290cc bike seems pretty rich.
  11. What kind of carb does the yz 250 f have?
  12. Thanks Burned! I tried bypassing the reverse switch if it was activating the rev limiter. I unhooked the wire from the selecter lever, nothing. Then I unhooked the reverse switch relay, still nothing. The machine still had that top end miss or bobble. So I put the 160mj back in, set the float level back where it was originally and the machine ran great. The whole problem before was a slipping clutch. I'm kind of new to this so it wasn't apparent at the time. I've since put a new Barnett clutch in and it works great. Thanks again!
  13. Thanks Burned. The problem does occur while accelerating and holding at a steady throttle. How do I go about testing this? There is a wire going to the reverse selecter lever. Maybe if I disconnected this wire it would disable the reverse rev limiter switch?
  14. Thank you for your reply burned. So how do I go about testing this? Yes, it does this while accelerating and at a steady throttle position.
  15. I just recently completed motor mods on my 88 Warrior. I installed a Four Stroke Tech 446 big bore stroker kit. It was suggested I bump up to a 160-165 main jet in the 36mm Mikuni BTM on the machine. I did this along with a Pro Design K&N w/ outer wear. The machine seemed to be running lean. I soon discovered I was running to hot of a spark plug, D7EA NGK. I bumped up to a 180mj and 2.5 turns out on the pj with straight Citgo 110. I was running 50/50 93 and Citgo 110 before. The machine developed a 1/2-full throttle flutter. It seems like a miss almost. I thought it was still to lean so I bumped up to a 200mj. There is still that 1/2-full throttle flutter. I am at a loss here. I don't know if it is a fuel system issue, or a spark issue. I've exhausted almost all of my options. Please help! I should also say that the needle jet is at the 4th position. I have also played w/ the float level a little also. I thought the bowl was running out of fuel too fast. I understand this is a four wheeler and this mostly bikes but the input would be greatly appreciated !
