Jred pistons 910 / 90

[Tdkclydes]

Can any one tell me if the pistons are the same for a Jred 910 and a 90 . I believe the 910 piston came in 2 different ring thickness .


Thanks Tom

I know the 920 and 920 Super are 54 x 1.5mm.. just had one of each apart, Pistons are identical, though the jugs are different.. the 920 doesn't transfer through the piston windows, the Super does.. and makes a whole lot more power for it...
I don't know about the 910. From what I read on Acres site it's the same bore and stroke, probably the same piston design, but it doesn't mention ring thickness there.

Part number for the 54x1.5mm ring is 503 08 17-01
