Jets, gold spring, N&S are all stock...

The only difference is the Gold spring that yamaha used back then, is NOT the same gold spring that Mikuni used, and provides in the rebuild kits.. But if your PO is 50, then you are fine!

You have another issue somewhere, no doubt.. Fuel pump could be one... do you possibly have a leak in your pulse line? I wonder if (worst case) your crank seals are leaking...

when it's bogging on the water, if you slowly manipulate the choke.. does it help?

Re: venture 1100 keeps blowing crank seals

Which line is the pulse line ? The crank seals all seem to be in and not leaking .. (finally) how is the fuel pump checked ? im getting seriously frustrated with this ski .. so many hours of messing with it ..

i don't understand why it is so difficult to figure out .. ?????

Ive also messed around with the choke lever while trying to run the bike and it doesn't seem to do anything .. another dead end !!!!!

The pulse line is the one that goes to the motor (lower cases)

It goes from the fuel pump to the lower portion of the case , right ? I will replace it as well .. I think it will be smart to replace all the fuel lines , including pulse line .. then see where we're at .. I will keep you posted ..
