First off want to say hello to all you guys.. Its been a long time since posting on here..
What I've ran into is a customer has brought in a 2006 YZ450f 50th Ann needing rebuilt.
As soon as I went thru the box of parts I realized that the Head was not a Yzf Head, Well, at
least not an 06 up head being that it had the Oil line manifold and Ports in the head for the oil to
reach the Head,,.Contacted the customer and he said the guy he got it from said it had blow by and he took it apart
to see what was wrong and got frustrated with it and decided to sell it.. The customer then bought a
GYTR Head that has been CNC ported and looked really nice..But then it hit me about the cylinder.
My concern is that if the Cylinder is not an 06 or newer than its not going to have the oil passage up thru the dowel holes
to enable the oil to reach the Cams.. Also what made me think about this is that the two 8mm Bolts on the
cylinder head that bolts to the cylinder go straight thru the cylinder holes and need a nut on the bottom
just like the YFZ450 cylinders do. The YZ450 cylinders 06 and up the two 8mm bolts thread down into
the cylinder..you can see the pics to understand better what I mean,,
Hoping someone on here (gray racer maybe) can help identify the cylinder I have to
be sure that it is an 06 or newer cylinder.. The person that the customer bought from told him afterwards that the origanal
head was off a 06 Wr450r.. Hence the oil lines.. Thanks in advance for any and all help guys.....
