Which dual ring piston to use????

[badass1000]

I hope the dual ring spis show up 11/28. I ordered two sets 9/26. The release date was 10/5 at that time and has changed several times since.
I would like to try them out. I am about to throw in a set of the hyperdrives. I only bought the hyperdrives because I wanted a spare set and they didn't have any t mollys in stock.

RKT's drop in for me. Works great. Other than having to deal with the owner and his very opinionated conversation. No more cast pistions for me.

kelsey is no fun to deal with imo.



wiseco all the way for me, only types of pistons i have experience with in sleds is stock cast and wiseco. Never needed to try anything else, once the stock ones are ready tobe replaced, in goes wiseco, warm up the engine properly and forget about them.

(even in mx bikes, vertex, wiseco, pro x etc, always end up trouble free with wiseco)


cast < forged

I have never used wiseco's in a xp. Had too many problems with them in the past with other sleds. Same experiance with a few other guys I ride with. They seize, even in the middle of riding for 20 min after a full warm up. Also had a few sets that the skirts cracked on and a few the skirts broke off.
Several friends and I have ran nothing but spi pistons in our xp's and havn't had any problems. I just put a set of spi dual ring pistons in my xp. Going to try those out this year. I have ran spi t mollys for the last couple years with no problems.
In my four stroke street bikes it is a different story. forged JE, CP, and wossner.
