@nickopedia56694 жыл бұрын
but they do? Well maybe you could get away with it if you are just changing out the valves and not repairing anything, but the service manual says to always re-cut the seats so the valves can wear in properly. At the same time, don't even bother with replacing the valves if you're not going to cut the seats, just clean them of deposits and remember which one goes where. AND NEVER LAP THEM. they are usually coated on these high performance engines.

loctite 638 isn't a regular threadlocker. It's a permanent retaining compound, and I would trust it far more than a shrink fit on such a thin-wall aluminum piece. A shrink fit is only as strong as the weakest component in it.

Not if it's your bike and you're doing it cause you like machining. A decent condition used head is usually $400-$500, vs maybe 8 hours relaxing in the shop (and I'm a novice, this guy probably spent less than 5 hours, with 2-3 hours of that being setup)
@anthonywilliams46384 жыл бұрын
Unless this engine is going to be used for low speed commuting, then the decision to use Loctite to keep the sleeve in place is fatally flawed. The sleeve should have been shrunk into the head, with the head heated to about 450 degrees in an oven , and after cooling the inner face which would have been machined smaller than the diameter of the valve cup, would be machined to clearance size. In that way, the machined sleeve will stay in place even at racing speeds. j
