valve guides
Hi all
I am in the middle of a full engine rebuild on my girlfriends 640 adv it a 2003.
I am reconditioning the head, new valves and guides,
I have reseaved the new guides from ktm and they don’t fit the valves.
The internal diameter is too small, after speaking to the dealer he said that they come unfinished and they need to be machined to the correct diameter after being fitted.
I have never come across this before on a rebuild, so is this correct?
Thanks Iain
