I don't have any hydrolock issues. I have Steve's overflow tubes.
But just curious: does this dreaded disease happen with a combo bad (or on prime) petcock and a sticking needle?
Or can it happen with just a bad (or on prime) petcock?
-
Usually both have to fail. If you leave the petcock on prime you are depending on all 4 float neadles to work correctly. Myself I never use prime. Infact I only used the petcock twice in 18 yrs and that was for reserve. I did replace it a few days ago 'cause all this talk about hydrolock me nervous. I have the overflow tubes but really don't want to see them work. Only when they have to.
-
Both the float valves (well, one of them) and the petcock have to fail (unless the petcock was left on "Prime") for hydrolock to occur.
-
So, lets say you accidentally leave it on prime, but your float valves are in fine working order. Where does the gas go? Or does it just stop flowing at some point?
-
The needles sHOULD stop the flow; unfortunately as the needles age they lose thier resistance to the fuel pressure, and can be un-seated by the pressure of the fuel. Steve

Are the needles not aluminum? They always were on my 2-strokes (RZ's and RD's).
Steve, did you change them, or do something to them when you had my carbs 15 or so months back?
Not asking you to remember my carbs specifically, but what happens with the full $300 service?
Bike runs like a million bucks, btw!

I know the answer to that, magic and voodoo. :thumbs: :rotflmao:

If the float valves are working properly, the gas doesn't go anywhere. The carb bowls will fill, and then the flow will stop.

Todd - the 300.00 service is disassembly, polishing the seats, cleaning (I use an ultrasonic tank now) inspection of all parts, reassembly, installing the 2 minute jet kit, installing overflow tubes, Setting fuel float height then filling and checking / setting fuel level, providing the drain tube system, and shipping back. If the carbs need extra parts, IE needles or orings there's an additional charge of up to 72.00. If your carbs were 300.00 you didn't need the extra parts.
I do use aftermarket stainless steel needles. The stock aluminum needles will corrode from water, and ethanol / additives can also attack them. Additionally, the needles I'm using have higher spring seat pressure, so they control fuel level better. HTH, Steve

If you are going to get the tubes and the 2 min mod you would be wise in my opinion to get the carbs gone through by Steve. To much work removing them and installing to have to do it right away again and worth the peace of mind IMHO. Having said that I wish I would have done that with mine this winter.
