What piston to use?

[SandNut777]

HI Guys,
I just bought a punched out 440 cylinder off Ebay and im wondering what piston to use? Its a wiseco sleeve. I have heard great things about JE Pistons and i am leaning in that direction. What do you think.

2001 400Ex
ITP Pro 9 wheels all around
New Holeshots on the front
ASV Pro Pack Levers
Aluminum Air box
Wiseco 11.1 Piston
Stage II Hotcams
AC Blackline Pro Peg Nerfs
Douglas blue labels with ITP Sandstars
Pro Curcuit T-4 Slip-On (Not on bike to noisey for the neighbors)
Renthal Bars/Pro Taper Grips
DG front Bumper

440 Cylinder head going in
Bill's Head Pipe on order

Can't go wrong with Ross, JE, or Wiseco.

If I had a choice I would pick the piston that is the lightest. There is a very small difference in weight between those manufacturers. On my 416 bore the difference between the lightest and heaviest of the three (Wiseco, Ross and JE) would see an additional 157 lbs load on the rod at 9100RPM!!


Make sure you measure the cylinder first to verify it is the right bore size before you buy a piston.

Yeah, I'd agree with him, only I've never dealt with Ross, but Wiseco and JE are great.
