    Will this bonehead move damage my CRF?

    The White Bro's tip on my 03 has a slight upward angle to it, at the track I launched my plug over the trailer parked behind me and into the cow pasture next to the track. Don't know how far it flew because I never found it.........

    Crack or a Blemish During Casting?

    My 03 and 05 both looked the same way when I had them apart.

    Manual Cam chain tensioner maintenance

    Installed mine, after a rebuild with new cam, chain and guides. Needed adjusting once after a few hours, as the new parts settled in and has been good ever since, I checked it several times but it has been good.

    Help with shimming please?

    Just do a Youtube search, just about anything you need to do to a CRF450R has a video posted there. Rebuilt my forks, replaced my crank, installed a cam and adjusted my valves all with help of Youtube.....

    broken kicker common?

    The "kicker" on my well used 03 has a good size notch in it and I'm sure it will let go soon. Guess I should order a new one before it does???????

    Broken clutch plate

    To answer your question.....If your wanting to ride this weekend while waiting for parts to come in.....yes, a file job will get you by till the UPS man drops off your new parts.......but do not think its a long time fix.

    08 wont shift

    Mine did the same thing last time I had it apart, took it apart 2 or 3 times before I got it right, the shifter fork on the clutch side of the shifter barrel was not in the groove all the way. Would shift till you tightened up all the bolts then, would bind up and not shift.
  10. Just remove the valve cover and left side cover, pull the fly wheel (you need a puller, 20 bucks), remove the cam sprocket, remove the metal crank sprocket guide, remove the two plastic guides, drop the chain down the hole, pull the chain out the bottom..........You Tube is your friend..... videos for almost any CRF450 repair

    First time at track.. nervous!

    Look for a track that does not have doubles, lots of tracks geared for beginners only have table tops (if you come up short you just land on top), once you can clear those your ready to try a small double.......

    what to look for in buying a used crf 450?

    Do not be fooled by new plastics, graphics and seat cover........Very cheap way to make an old dog look like new....
