2 Strokes Down Under

Hi All,
Anyone familiar with these pistons. I have just done a rebore on my H2A. On the piston box was the recommended piston to bore clearance so that was all OK. However there are no instructions as to the rings. The rings have the same part number on the bags they come in so I assume either can be top. Both of the rings have a 'N' stamped on them....I assume this is the up mark and would be installed facing to the top of the piston. There is also no info as to the ring end gap. I guess I use the stock H2 ring gap. The most interesting bit is the pins in the ring slots on the pistons. Both the pins are in vertical alignment at the rear of the piston??? They are not set apart from each other like all other 2 stroke pistons I have seen. Usually the pins are set apart from each other and between the inlet and transfer ports. The ones on my pistons are directly in line with the centre of the inlet port. Is this normal for Wossner?
Be interested to hear from anyone who has fitted these and if this is 'normal' for these pistons....I assume it must be but you never know!

Thanks

Sounds like normal H2 piston. Never touch the tongues on the inlet port window.
