Re: 49cc vs 66cc
Actually thinking back I'm wondering about the photos above -
my head and jug look just like the ones listed as 55cc- but I measured the piston a few weeks back and it measured EXACTLY 40mm- I posted a query here as to the width of a 66- not wanting to take mine apart- and the answer from somebody else was 45 I think.
so I'm not sure if the picture is that acurate- at least my square head and that kind of jug has a piaston 40mm.
I think the stroke is the same they seem to advertise the same connecting rod on ebay- but you know how information is on all this- plus through the years they've shipped varients and people talk about them here
My 66 is almost 3 years old now- and has 6 mm studs- I think 8mm is pretty standard now.
