I have an old mountain bike i put together about 3 years ago. I was hoping i could just put the engine onto that but im not all to sure it will fit.. Can someone give me the minimum size of a bike a motor like that would fit onto?

Thanks!

I can certainly give you the minimum, which is my mountain bike.
From the top of the crank case to the bottom of the um... top bar, whatever.
The distance should be at least 13", with that space though you will need to offset your carb.

My Pig measures 12 inches from bottom bracket to top tube. I could not fit the air cleaner because it was so tight. Anything less than 12 inches will be very tough to make work.

Some of my space is taken up because of my large down tube adapter.
I need to use a couple nuckle joints on my torque wrench for my head because the torque wrench won't fit.
