You couldn't be more incorrect. But I don't really care if you want to wallow in your ignorance, if you want to use KB that's up to you. I am sharing my experience freely with someone who asked for help. I've seen these failures my self, no pan era 'wrench' is going to convince me I was imagining things.Dron54 said:Well, you can tell HD Tech is a MMI grad, brand new at that. If anyone 'cracks' a piston, hyper or not, they AIN'T a wrench! If hypers were so hard to use with pinging and deto, why does EVERY OEM in the world, harley included, use them with their leaned out, EPA tunes?? They say ignorance is bliss, I wonder if this is why Dealers are only allowed to hire from MMI?? :blink:

Dron54 - I respect the opinion you offered with regards to the question ask and I am sure you have a lot of experience that would be very helpful on this forum. I also respect the opinion that HD Tech offered based on his experience. What I don’t respect is how you attacked HD Tech’s qualifications and experience. One of the rules of this site is, you can differ with others opinions but you don’t attack the individual or their qualifications. I don’t feel the comments about HD Tech being a new MMI graduate were necessary. Just my opinion.Dron54 said:Well, you can tell HD Tech is a MMI grad, brand new at that.

You might want to check who the gun is aimed at before you go all girlie on meDron54 said:A totally false statement was made and I pointed it out, sue me. The analysis about qualifications was derived from that same rediculous statement, take my first born. Reading the threads Springer posted would explain all of this and we would'nt be bickering, steal my truck. Now that I'm worth nothing, bye.:bannedmf:

"Best" is a relative term. Like Springer said... it depends on your application.HD Tech said:I've had excellent results with SE pistons, both the cast and Forged (ARIAS) and Weisco. The latest Weisco are very up to date. JEs seem to be dated or low tech. KBs are junk, very brittle, I wouldn't even put them in a mild build, they don't seem to handle detonation or pinging at all.
I've seen alot of these "which is best" piston threads. You got your Cast camp and your forged camp.atengnr said:I m only a hobbyist, but heres my opinion....For a flat top, KBs are the way to go. You can run them at .0015" piston/cylinder clearance, for good seal, quiet operation. Wiseco forged need something like .0025", and also because thermal growth, etc., will definitely make "slap" noise (pistons slap)when cold.
