Alas Another Uncle Phil ST1100 Mystery Thread

I am so glad you found this was the issue and not the one that has occurred over here....

In the UK I know of at least two owners who had their alternator rotor windings swell up with corrosion and cause the alternator to present like a seized engine..... 40 amp versions only.

I advised one to soak his alternator with ACF50 to see if it freed up enough to get to a workshop, fortunately it did.....

Some faults can only be found by taking the most bizarre possibilities into account......

Yup, and new ones aren't easy to install if you're not familiar. Why I made my own and sell them in here.

BTW, do your replacement ones require the little metal clip to keep them in place like the 'stockers'?
 
Ah, forgot my announcement got wiped out with "The Purge". The Honda wing logo and "ST1100" shown are most common and can paint or leave them unpainted. Or customized faces. Guess I need to rebuild those posts.

Me wonder if mailing to Canada is possible these days?

"No, bc they're part of the reason new ones get bent installing them."

They sure do fit tight though as I recall. Hope I won't have to remove em.
Worked great on the left side to mount the heated grip rocker switch.

Its possible, just not cheap. I haven't sent stuff up there recently, but I will guess in the $18 USD range for international first class, just for shipping. A pair of plugs starts at $12USD.

Bought some from mother Honda a couple of years ago, probably what shipping will cost me. Left side has a cigarette lighter out let in it. But yours looks excellent with the embossing.

So for Europe that would be:
12 + 18 + 20% import VAT + 5% handling... aprox 38,- total... :cautious:
If they even would let the shipment pass... an unknown variable these days...

I haven't done any shipping since the tariffs were enacted...could be more. AFAIK, most countries have figured out how to handle US posts now. I agree it seems silly to pay 2x more for bits of plastic you might not even get now. Can you wait 3 more years?

That's not thinking outside the box... That's thinking outside the truck that brought the box.
Nice save that.
 
I hate to divert the thread drift (;)), but I got to take that ST1100 out for a short test ride this afternoon.
After syncing the carbs with my Flowmeter, it purrs just like a fat, happy cat and runs great.
The real issue was that one of the plastic Honda T-fittings that are in the vacuum lines that run along the top of the carbs was cracked.
But it was a crack that you would not see unless you pulled all the lines off the carbs.
The symptoms were a faint surging when you backed off the throttle but it would run fine when cranking the throttle.
Now I can get to my 'original' project of installing front/rear recording cameras and a BSD system.
This is all cheap Chinese stuff but I want to see how the concept works before I drop a load of cash 3 times. :biggrin:
The BSD is 77GHZ just like the INNOV system but the longevity may be the issue.
I'll start another thread on that subject once I get some time into it.
Thanks again for all the suggestions - especially about the hydro-lock!
In 1/2 million+ miles on 4 ST1100s (without the fuel cutoff) that is the first time I ever encountered it.
So maybe I'm good for another 1/2 million miles now .... ;)

I have never heard of the 1100 having hydro lock before myself. I don't think the fuel cutoff valve matters. All it takes is one cylinder to have a little too much gas in it when the valves are closed and the piston comes up.

There's one in the 1300s' coolant lines that becomes brittle with age and heat of the coolant presumably. I think when it goes there's no hairline crack. Someone here was/did work on making a brass replacement. It made me think of carrying a spare and two or three forceps — just in case. Never got roundtoit.
 
Well, the carb issue is back with a vengeance on Frost.
I just took her down to RanchSToc and back and she acts 'flooded' when she has run awhile and then stopped.
Does not want to start easy with or without the fuel enricher (choke).
Once she starts she runs fine so my hunch is the float 'needles' have gone south.
Someone where in Uncle Phil's Parts Supply is a set of newly rebuilt carbs.
She is also running hotter than usual (about 1/2 gauge) even on the interstate.
Fan kicks on at the 'appropriate' time as it should.
Running it up to temp and watching the thermostat action with the cap off (you can do that with Evans) it appears the thermostat is flaky.
Sometimes it opens fine and sometimes it does not judging by the flow at the neck.
Still checking other issues but the coolant level looks fine.
It must be the HMW stickers on the shelter ... ;)
