CRF's Only Forums

I would greatly appreciate any and all help I can get. I am new to this and I am looking to learn. Thank you in advance! I want this bike to be a real blessing to my son so I am trying to work out any issues prior to giving it to him on Christmas day. Here's my situation....

I just purchased a 2004 CRF70 for my 10 year old son for Christmas. I've taken it out on a few test rides and shifting seems a hard, jerky, clunky, stiff, etc. There's a noticeable jerk shifting from N into 1st. Shifting from 1st to 2nd is the hardest, jerkiest, clunkiest of all. There is a pretty good THUNK from the gearbox when I shift. Going back from 2nd to 1st is just like you hit the brakes hard and suddenly. Almost causes a skid mark.Going from 2nd to 3rd is relatively smooth. The idle speed seems right. The oil in the gearbox is new. Starts 2nd or 3rd try and after a few minutes just sits there and idles "smoothly".

I have no instruction manual but found several posts and a video on adjusting the clutch which I have done several times without any noticeable change in the shifting. I've read where a 13T sprocket on the front may help. Like I said, I am new to this.

Is any of this normal for the CRF70? Any other things I might adjust or modify to make the shifting smoother?

Thanks again and Merry Christmas,

Mark

This may be completly unrelated but on my wifes clutchless quad (TRX250EX) it was set a bit high on the idle which was causing the shifting to be real hard and jump. Especialy from N to 1st. We turned the idle down and it shifted like butter.

My son had a TTR90 and it did the same thing. Adjusted Idle, all OK. I never downshift from 3 to 2 to 1 unless I'm stopped. It did lock up the rear end.

Change the oil if it hasn't been changed. Use the specified Honda oil.. It will make it shift like butta!

The 13 tooth FS will help too. Downshifting to first will lock up the rear if you are going at any real rate of speed.

How did the bike come out? Were you able to correct the shifting problem? How did you kid like the gift! I remember my first bike, it was the best christmas ever!
