Why SIG Extra 300 XS so tail heavy????
Mine need the full 16oz treatment as well, I thought I had lost my mind.
I checked, double checked, rechecked and yup, the manual says thats the size engine to use.
My Saito 180 is about 3/4 of an inch further than recommended and also have put to battery on top of the gas tank access hatch.
This helps quite a bit.
