1995 GTX Carb rebuild issue

[RickH]

I’m rebuilding the carbs on my GTX and I was looking at the different kits out there and ran into a potential problem. It seems the spring for the needle valve, Part No. 270 500 242, is no longer available or a close replacement. Has anyone had this problem before and found a remedy?

Buy it under the Mikuni part number. 95 gram. Dull silver 730-03027-T
BN 38I (improved)
check with Seadoo Source they may be able to help.

Just follow this to the letter...

If your springs are not damaged there is no reason to replace them.

No, the 270 500 242 is not a 95 gram spring.
It is a 65 gram spring, Mikuni number 730-03033
It was only used on the 657X motors and the RX-X.

Thanks Mikidymac, I just thought with the age of the PWC, it might be good to change. I found the 730-03030 on line, so that is the spring Seadoo calls 270 500 242. Also, I read your Seadoo Carb rebuild thread. Absolutely outstanding, people like you make us DIY’s job soooo much easier. Thank you very much!

No problem, got to keep these old skis on the water.
