RE: Welcome to Club SAITO !
Here are the weights of three Saitos, a new/old .65, very early high compression .80 and a blue and white box .80. The .65 is always said to be heavy, it certainly is.
Picture #1 is the .65
Picture #2 is old GK
Picture #3 is mid aged .80
Picture #4 is velocity stack made using the choke retainer plate and piece of wind chime tube.
I put the same cast muffler on each and the same prop washer and nut, the GK lacks a vent tube but I ain't doin this over for that.[8D]
PS, my arm has come a long way, I have pushed hard to get this passed me.
