Jets?? 64.95mm pistons

[rkooienga]

I assume if I bored my motor from a cast 64mm piston to a cast 64.95mm piston I am going to need to change all the jets. I don’t know which numbers for all the jets.

No need to.

So if im running bored cylinders with Stock carbs and stock pipes I dont need to get bigger jets?

Correct, No reason to rejet.

Awesome thanks, I really would have thought with a bigger bore that you would need to replace the cylinders. Thanks

I am new to cylinder boring, So if I bore my motor. I already know you dont HAVE TO change the Pipes or jets. Is there any mods I need to go with this bigger bore?

No, a bigger bore on stock cylinders simply freshens up the engine. That part will be like new again.
