hey just got a 2006 x fire 700. has 5700 miles so im thinking top end rebuild time can anyone recomend a good set of pistions. i was thinking spi's

Just get the stock ones from a dealer, some aftermarket pistons are better than others, but I wouldn't call any of them good.

another vote here for OEM pistons

go with wiseco pistons. other than my slopro every time i rebuild a motor i use wiseco pistons, i would use them on my slopro but they arent available. they are lightweight forged pistons, lightweight giving you more power, faster revving, and the forged giving the pistons alot more strenght and durabilty over orm pistons. and they are dual ring design unlike how they used2 b, so they last just as long, if not longer than oem pistons!

Forged pistons suck.......including Wiseco. They will end up sticking, breaking a skirt or catching a port. I will never put Wiseco pistons in anything except the garbage.

Another vote for OEM.

I agree, I wont put forged pistons in a 2 stroke EVER. but a 4-stroke likes 'em..... leave em to the yammi guys.

yea i wouldnet touch wiseco's i was thinking spi's used em in other sleds and had no probs

SPI's I know about half dozen sleds that used them, NO PROBLEMS what so ever, several were mine. Don't let anyone who doesn't use SPI's convince you not to use them.

Go with oem and have them ceramic coated!
