300/440/550 Not sure which popoff to get 87 js550

[onelugnut]

My first post so be easy on me. Going to rebuild the carb on this ski and would like to order all the parts I will need. I have done a search and can not find which popoff valve and spring to get.(at least to start with). Is there a good site to order from that is on the left coast?

Thank you!!

I'm assuming you have a bn44 carb? Mikuni has upgraded there rebuild kit's to 2.0 n/s with i believe a 14# pop off.You can double check on the Mikuni watercraft web page and any good Motorcycle shop should be able to get it for you. Or order it from Mikuni but only buy Genuine Mikuni Rebuild kit's
