wiseco piston

[dempsey400]

Anyone here run a wiseco piston in there 400ex. How are they?

[cals400ex]

my friend has a wiseco piston in his bike and it hasn't gave him any problems. if it was me i would probally get a je or ross. i like the ross because the overall weight is lighter.

I run wiseco and I don't have any complaints with it. I know everyone claims that they don't advertise the right Compression Ratio, but mine has to be close because I have the 11:1 piston and when it gets hot it pings with 91 octane.

There was a very good reply from Wilkins250r about pistons in an earlier thread. I can't find the thread right now, but if I do I will post the addy.

Wiseco and JE are made by the same company! Just to let you know:D

Mine is a Wiseco as well. I had a Wiseco piston before that lost a circlip and ruined the top end. I believe that was my fault though.
Ive had my 435 kit in for just about a year and have been happy with it.

Correction they are owned by the same parent company not made by the same company they operate independent of each other.:)

Mine is good so far. I would worry more about the machine work. make sure it is done right.

My bike runs awesome, no complaints. I had a circlip come off on my first attempt at a 416, too. I wonder if a couple sets of circlips found their way into the wrong boxes? Either way, Wiseco took care of it and sent me all new parts including a sleeve and gaskets. I've never had a problem before or since.
