I have been thinking about doing a FM 107 kit. I brought a used set of stock 103 and 96 jugs. Would there be an advanage using the 103 jugs to do a FM 107 kit? Would the walls of the 103 be thicker after being cut to a 107 than if I used the 96 jugs?

 

No, the cylinders are all the same (they can make either work).

 

Yes its same cylinders, harley just bored the 96 to 103.

 

If you are going to have a left over set that you might sell, the 103" jugs might be worth a little more for someone wanting to upgrade a 96" motor, if they are in good shape.

doesn't FM have a more robust jug for their 107 build, like thicker walls ?

 

Yes they do, making their own thicker ones now as an option. After Jamie tells the whole world that stock to 107 juggs have and will never have a problem, even with huge mileage. Hmmmm...

 

I'd go for the more robust jugs ( crack myself up saying that).

 

Yeah, robust jugs.

 

Don't **** yourself for a min. Jammie has some great **** I wound put it up to anyone's stuff,That there is the facts Jack

 

Yes... both sets are in great condition.
