Bad experience with Wossner pistons...
cobbs:
you guys need to stop giving cast pistons a bad rap they are pleanty strong for any type of motor your going to build the only time I would ever require or need a forged piston is if I'm running nitrous and I know 99% of all k5s are not so I guess I don't see eye to eye with you guys on the cast vs forged debate personally I think cast pistons are much better if you keep good tolerances on everything they will most certainly out last an expanding and contracting forged piston the reason why so many people have cast failures is because they ride the s**t out of their bikes and the don't maintain them and keep riding them till they fail then blame it on the piston that's called a defective owner I've NEVER seen a cast piston fail when the bike was maintained properly. That being said I just had my bike replated to freshen it up and I ordered a pro x with it and they sent a wossner I wasn't very happy but I threw it in and it works fine but not necessary so I guess to make a forged piston worth using I guess I'm going to have to throw the boondocker nitrous kit on it that I have sitting around

I think cast pistons are great!!!....you can get a 15-20 foot spread when you shoot a 30.06 through em from 75 yards!!!....won't see that with a forged. :-D
cobbs:
make fun of forged pistons all you want I don't think some of you understand metallurgy at all so I guess you wouldn't understand why cast pistons are better for non nitrous motors, just because forged pistons expand opposed to cracking or breaking doesn't make them better I've seen SEROIUS damage happen due to forged pistons expanding, cast have no expansion or contraction so you can run tighter tolerances which means the motor has less stress and slop and less stress and slop means longer engine life peroid.

read the "wiseco blues" thread....ALL the proof ANYONE needs is all right on this site....just have to take some time and search.Some guys like/swear by cast,and I say good for you,and best of luck to ya...I'll never run em in any of my toys!!!
cobbs:
well I see your comment says "if ya run cast you come in last" I'll race you :-D anytime I guarantee I don't come in last :evil: I know everyone is entitled to their own opinion but I don't think any of you took classes on metallurgy and how metals react to certain conditions so like I said I doubt you would know so I don't blame you and I've read all those threads and they don't prove anything there are so many variables when a piston fails 90% of the time it had nothing to do with the piston like a bad crank, bad fuel, bad filter, wrong jetting etc and none of those things have anything to do with the pistons quality or lack of quality so if you ever want to put my bike against yours I'm down (but for the time being I'm sort of a hypocrite cause I still have the wossner but at least I can try the nitrous with it) I'll show you boys what cast can do he'll I'll make my own comment "if you run cast your whoopin ass" :-P
