50 mm buckshot question for ultra
what rebuild kit should i use for a set of 50mm buckshots, and also what springs would you recommend for a single pipe ultra?

You dont need a rebuild kit since most of the parts wouldnt work. I think the diaphram is from a mikuni sbn. If they are original then the needle and seat is a automotive type. The part # has been posted a few times so you should be able to search here or on the ultra board and find it. If I remember right I used a 95 gram spring and it gav me a pop off of 21psi. The jets were 160 high 110 low for a level 1 motor.
