05 R cam in 07 CRF 250x Question
Posted 17 July 2012 - 11:18 AM
Ron Eyers shows two part numbers, two prices 670 being about $5 more:
14100 KRN 670
14100 KRN 730
Which one should I order?
Is there anything else I should replace when I install this cam…like valve springs, retainers, cam buckets? Any other advice?
Thanks for your help.

The 14100 KRN 730 is the 05 grind
The 04, 06 cams are hotter on the top end and lose a little on the low end when compared to the X cam.
The 05 cam gives a boost through the whole range but not as much top end as the 04 and 06 cams.
Another good choice for the X is a Stage 1 HotCam. Awesome boost in low and mid range with out any loss on top.
Basicaly it all boils down to what type of riding you do and where you are wanting more power .
As for replacing springs and such, any of the cams mentioned above are straight drop in cams.
you would only need to replace any parts that show wear.
Hope this helps.

Has anyone compared a 05r cam to a HC1 cam on a basically stock (JD jet, airbox mod, cut baffle) 250x?
The bulk of my riding is 2nd & 3rd gear single track with a few laps around the mx track.
