Sorry, can't help myself. Want to add a little..
Heck, (ya'll will all agree) when someone tells us,, "that can't work",,,
It makes us "more" determined to make it work.Steve gave us a absolute way to save the bikes from Hydrolock. (THANK YOU,, Steve)
Let's keep discussing a way to prevent fuel leakage to the carbs.
M in SC. I need a clarification.
Harry said that the C-19 Petcock "internal" piping is 1/4". (It has 5/16" O.D. nipples I think).
Your 1/4 Nippled valve can't have a 1/4" O.D. hole thru the (1/4" O.D.) nipples. {EZ boys}
Please measure the I.D. size of the hole.
NOTE: A simple way to check for too much restriction in the C-10 is simple.
You don't have to do 100 mph runs to check the flow.
{Safer way} Open the valve
only a little and see if you can make the bike starve for gas during a quick WOT accell.
If it doesn't cause a problem, close it a little and repeat.
When it becomes a problem, go home and do a flow test.
The number you get would be a baseline...
M.O.B. you made a point that the solenoid isn't properly certified.
I agree with you, but
we've been modifying and installing parts on the C-10 for years that were not made for it.
ie; If it works, (we don't need no stinkin' certification)
You have more engineering back ground than most of us, help us find a simple solution.
JDM/others, on the Solenoid valve, is there any way to check flow?
If m in SC comes up with a base number, we could use it for a comparison,.
Ride safe, Ted
PS: Lets go back to the Tank venting discussion from Steve/JDM.
Many bikes are running with valves or filters in the lines and are not having flow issues.
Others bikes won't accept any (valve/filter) restriction.
Maybe; The tanks vents (which are as old as the petcocks) will end up being the Root Cause of the flow problems, "and" petcock failure's..
