Just baught a crf and it's my first fourstroke. I've always had two-strokes. What is different

with maintenance on these machines if anything? besides the regular stuff.......

ie, valve adjustment, carburator ect........ Thanx for any help.

Your question is not unlike "mommy, where do babies come from?"

Change the oil every 3 rides. Make damn good and sure your airboot doesnt and cant leak.

It depends on your riding. My WR has never had anything done other than a oil change and lubing.

On my CRF I'll watch the valves a little closer. Change the oils OFTEN and watch there levels.

Tear the bike apart and lube everything.

Lastly...use the search. Most of your question have already been asked. But hey, it never hurts to ask :)


Check those spokes!!!

Don't worry about the maintenance at this time since it's new. Ride it for a month or two then start worrying about it. Other than that, just change your oil every 2-3 rides and check your spokes. :) more thing....

Adjust your chain slack when you see that it's loose (since it's a stock chain).

I know this has been posted a ton but don't forget to add the correct amount of tranny fluid. The check bolt hole is not accurate. So just add the amount specified and you are golden. :)

I would lube the swingarm, steering head, and linkages swith a quality grease before you even ride it. The amount of grease from the factory is little if any and there grease is substandard. Also, check your valves and decompression adjustment. I did all this sbefore I ever rode my '03 and have not had any problems yet.

      I need recommendations on Honda dealers with good Mechanics in Western Washington. I am in Puyallup but will drive for peace of mind. I have never had a dealer do major work on any of my dirt bikes. But long story short I am on a 15 CRF450R and it needs the 5th gear recall done. Any and all info is much appreciated!

      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:
      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?
