I've had great experience with JE, and Pro-X pistons, I don't see pro X up there, so I voted JE.

I have never heard of wicked pistons until I became a yfz central member. I have been around race bikes for 2 years and no one has even brought up a wicked piston in our talk. But let me clear one thing up. I run a JE piston(that is custom made) that I get through GT THUNDER. I have also ran a custom je 13 to 1 piston in my z400 and that bike hasn't been beat by any 440 kits. Yes there is other mods done to it but still a stock bore high compression bike that smokes 440's.I race 300ft. dirt drags and the only piston to run for great power is the JE.

well if you have only ran JE, how can you be sure it is the best? the wicked piston was designed april of this year. we just got our second order out to the public so ofcourse you havent heard of it except on here.

So how can you say that that the wicked is a good piston when it hasn't even been out a full season. I am not saying that it is a bad piston it could be the best in time. But for people to reply to this topic without even running the piston 6 months or even having prior luck with the piston is crap. Because if someone is looking to upgrade there quad but doesn't now a lot about pistons you wicked supporters could be leading them in the wrong dirrection (only time will tell) So lets remeber this site is to help people not sell your "NEW UNPROVEN" product.

b/c i have tested this piston. i dont know what you consider a full season. i go by hours. thats ok if you like JE. stick with JE you have had good luck with them. you asked for my opinion when you posted a public pole.

just a little tid bit. how do you think this site pays for the server

The Wicked pistons are and will gold up as good or better than anything else out there. They are forged from CP's latest forgings, with some added things tht now even the off the shelf CP pistons have.

Let me say again...the Wicked piston is a CP piston built to our specs...so if a CP holds up and you like it then you will like the Wicked as much or more. The design is a flat top high compression...this is the best of both worlds....1 a flat top is the optimal design for revving, scavenging, flame travel etc...2 at 13.5 compression you are getting the HP and TQ you need and want...all while revving out on top MUCH better than the current high compression DOMED pistons off the shelf.

I have ran the GYTR 13:1 actually about 12.7:1, and the JE (old Sparks) 14:1 piston...and just a tid bit of info for you guys Sparks no longer sells or pushes the 14:1 pistons, realibility and revability issues. Mine came out of my bike after about 20 hours with small cracks on the top of it. This was 18 months ago or so however.

colton..I know that you feel that "if the pros don't run it then it ain't good" But our piston has only been avaliable for a very short time, and just last week did the 40+ ship out to customers. Some ride reports will be coming in as time goes by....I do not anticipate anyone being dissapointed at all.

Had three GYTRs fail, let just say the 4th one we threw in the bin.........

Friends race team failed a JE13.5:1 in under 5 hrs, so bugger those..........

CP, good run with a 470 - 60 hrs.

So if the Wicked is an improved CP it looks like the deal.....................

next line of mods; Engine oil cooler, more head work, reprogrammed CDI map, better rod, CP piston.

Does anyone have a JE specially designed. Because that is what I am running. I have heard that the gytr is a lower grade JE. So I wouldn't grade them in the same class.
