hydro-lock..

Postby davebonaked51 » Fri Sep 23, 2011 6:36 am



1977 gl1000 , i have been reading the responses to the other person that had starting problems like i did yesterday. i also did not turn my gas off when it was parked in my garage. last time before yesterday i rode my bike was last week. so , how much does not turn your gas off contribute to hydro-lock ? it seems that is what happened to me yesterday. bike started right up cold. hydro-locked after i stopped at a gas station for 5 min.so, should i turn my gas off after every stop??

It's been my experience that a 35 year old bike MAY not operate perfectly(carbs) every time.Even after full rebuild,my 1000 and 1100 and the 1200 would once in a great while hydro lock.It's been related to one carb float not perfectly sealing the fuel off.Too many variables here,heat,cold,contaminates,ethanol gas,moon phase,my attitude,etc.

Until I can find a 100% guaranteed method of stopping this ,I turn off the gas when the key goes off and carry a plug wrench on the bike just in-case I forget.

Maybe I'll research a aftermarket electric valve.

If you are hydro locking with a 5 minute stop, I think you need to overhaul/adjust your carbs. It is not uncommon for them to leak a little, but to hydro lock in 5 minutes is a fairly large leak and suggests you need to set the float heights or overhaul the carbs and fit new float valves.

This is true if it happens very often.before ,at least on the 1100 it would hydro lock just 2 or 3 times a year not turning off the fuel.I ride year round.
My carbs were spotless,but once in a while,it would just leak past one float valve.Tap on the carb and all was well.Just one of those things.I guess that's why most newer bikes went to a vacuum operated fuel valve.

I keeps your oil thicker if you turn off your fuel at each stop, and fuel economy increases as well. At least if your 35 year old float seals are like mine.
