any ideas?

 

Man i dont know. dont think you are going to find a lot of hands on experience with that combo. FMF pipes and 28mm carbs are not a real popular combo with a Cub. You are neutering those cylinders. They like high rpm pipes and lots of air flow. You will want CPI, shearer or pipes of that like and 33-35 mm carbs to take advantage of that cylinder.

bigger carbs and better pipes are definitely gonna happen i just cant quite afford them yet so i was looking to get the motor running, then worry about them i know 28's are small and the pipes aint big enough either but it is only a 65mm cub but its what i got to do for now so if anyone can just give me a ball park idea id be stoked, i dont want to have to put it in a shop
