Thanks! Thats what I was thinking also, but Im repairing this for someone is this is the way he wants to go, so......
The sleeves are very thick though. Thinking they will go all the way to 72mm, and yes there is a good deal of money into the jugs already. Appears this poor guy purchased a kit including: Coolhead, pipes, big bore kit, 34mm pwk's, V force intake, intake boots and spacers, and a nice MX port job. Its all beautiful except "Someone put the pistons in backwards"!
