Dear friends, I am planning to install a new exhaust cam (with decomp device) on my 2002 YZF 426. Which one should I pick? Stock? Hotcams? Here's what I read on "thumperfaq" about the stock 450 cam:
"The 2002 and 2003 YZ250F and WR250F exhaust cams are identical except for the decompression device. So for about $160, the 2001-2002 250Fs can start just as easily as a 2003 model. This isn't true for the old 426F. The 450F cam gear has a different tooth pitch, even though the tooth count is the same. The new cam will work for a while, but the chain and gear will have accelerated wear.
Is is really true? Does the hotcams exhaust cam fits (and works) better?
Thanks in advance and greetings from Brazil!
