Fuel Screw

After my 03 has been sitting a bit it takes three to four kicks to start. The kick starter kicks easy enough it just seems that the fuel is not getting in there or something.

Someone remind me about what the fuel screw does and how it may effect starting?

I am not sure about the fuels screw, but i always pump my throttle 3 times before i kick it and it fires up everytime. I always turn my fuel off so the carby just might dry up or something.

I was told by the guys at the Honda shop to turn my fuel screw a 1/4 to 1/2 turn more. And I also snap my throttle 2 or 3 times b4 starting ,and I never have problems. Hope this helps

<font color="brown"> If your bike is really setting for a long time like a month or so just tilt it so you see fuel coming out of the overflow until you think the bowl has filled with fresh gas from the tank. It doesn't take very long for that little bit in the bowl to go bad and lose octanne I'm sure. I'm also a throttle twister, 2-3 times. Colder it get's the more I twist. <font color="brown">

      I have a 2005 CRF450R with a Trail Tech fan kit installed. I need a little bit larger tank and would like to know if anyone has an aftermarket tank that fits with the fan kit.
      I dont need a monster 4 gallon, just maybe a 2.4 or 2.7 from IMS would do fine.  I talked with both the tank vendor and Trail Tech and neither could give me any answers.
      Thanks guys.

      So I emailed Factory Connection today to see what spring rate I need for the rear as I’m about 6’2” 220 lbs without gear. I also asked for a baseline front fork PSI to start at. This is what I received:
      Nicholas, 
      The spring series we made for your bike is limited when it comes to larger/stiffer rates.  
      The spring rate you need is 5.9/6.0 range. We don’t sell that over the counter as it requires special installation process.  So we can’t sell the spring “over the counter”.  It would have to be installed at our shop.  
      Fork PSI I would recommend:
      Inner 160 psi
      Outer 11 psi
      Balance 160 psi
       
      Are they blowing smoke up my ass? What kind of ‘special installation’ could a spring take? I’ve changed and removed them before but not on a 16’ CRF before.
      Also, aren’t those psi settings for the Kawasaki KYB? I don’t think the psf2 have inner/outer/balance do they? Maybe he was having a bad day...or maybe I’m an idiot. FC’s website list there spring as ALS-0059. Can I not just order this spring and install it to set my sag correctly? Help?
