Joking.
Whats your take on Forged vs. Cast Pistons

I agree however in this particular case the focus is on a critical issue not something that is "ooops, oh well, let's try it again" like adjusting valves where the bike might run bad and need to re-adjusted... not much harm done unless you continue to run with it, who knows what might happen... in this case it's a case of "better get it right the first time" because it's going to be costly if you don't...
If anything have someone you know (a friend) who has experience do it or coach you thru it so the errors are minimal if any... jumping in all the way if inexperienced might have drastic results.
OK.....
..... next!Send me another picture of the sky in "your world". You won't notice anything I. Riding the two. Your 500 will continue to pull like a Baldwin with a single ring. It won't feel like it is reving any higher either.
of course 2 rings cause more friction and cylinder wear....dont know how big a factor that is. but it is a factor.
Wtf is this thread about???
Forged is better than cast.
There is more silicate in cast so it is less prone to cold seize.
Cold seizure is more prone in air cooled engines and cast cylinder engines. If you don't have 3 minutes to warm up your engine then you get what you deserve. If you don't own feeler gauges to check your ring end gap and your piston clearances then you get what you deserve. I was at one time ASE certified and Honda certified and trained. I do nothing without a manual for reference.

ok, just don't go on living thinking that silly notion about the low speed compression, or that low speed compression (as you put it) will affect anything you are going to notice. less ring drag is considered a good thing in some racing situations. if you think about it the crf's use a single compression ring, as do many other race rigs. don't bore me with "but it is a 4 stroke" please.
I'm not one of those photographic memory dudes unless the women are naked but I do remember reading miles of notes on these topics from seasoned vets and engineers. I remember them being called silicates for some reason. Wiseco currently uses more silicone derivatives in their pistons for better tolerances and to help prevent cold seizure.
I may have read that on their website.
I will add this, although one is better than the other, and I am no engineer, just a guy that can turn wrenches.
Any name brand product you pick will work well within its intended operating time, issues occur when things (pistons for example) are used beyond their intended service life. Pick one, run it for its time, and replace it. sleep easy.
