Dave Patrick ULtimate 1.20 Bipe engine????
I think you would be happier with more power....if you want to go with YS get a 140L. I have a Saito 180 on mine.......very good power.....not overly outragious.....a Saito 150 would be a good pick too, if you didn't want quite so much. I had a YS 120 AC on my Goldberg at 9 pounds.....your going to come out around 11 +. Unless you already have the YS 120 go with a little more power.....you will be glad you did.
