Did a nice run around after my carb issues but......

[Pony Ruiz]

I think the bike is running hot overall....

I only did ten miles in 50 deg cloudy/rainy Seattle weather and the temp gauge was starting to get above center as I was heading home. I didn't really get on it either.

I did notice the fan was on after I stopped so at least that is working...

Not a new thermostat so I am wondering if that is working ok...

Seems like it should be in the bottom 1/4 of the gauge esp. at 50 deg outside.

What is up?

Other than that the bike is running gooooood!

I will give it another go manana - to wet right now.

 

[danf]

Your correct, it shouldn't even get to the half way point in those's temps. Thermostat is probably your best bet, test it or just get a new one and replace it...I say it should be in and around the 1/4 gauage area, and that's based on my bikes esperience....

 

[dan filipi]

Yeah, running at 50 degrees should be around 1/4 gauge and fan shouldn't come on til 3/4 gauge.
I'd try a new thermostat also.

 

[Pony Ruiz]

Went out and started it in the driveway....

I was thinking the thermo was stuck cause I opened the rad. cap and the water was cool.

I ran it and let it sit for 1/2. Should have been warm I think.

this time ran it for 5 min and checked the water it was warm so seems like the thermo is opening.

what is that two prong thing that is on the side of the thermostat? Sends the signal to the gauge?

I will change out the thermostat for good measure... then if it is still hot?

 

[dan filipi]

2 prong is the fan thermoswitch.

 

[joedrum]

heck pony id take that thermostat out....and bolt it back up.....your thermo switch is obviously working if the fan is coming on....if after riding it is still getting hot or rather warm ...theres something else going on ....un less you just want to buy a thermostat and hope thats it ....personaly i dont use thermostats at all ...past that i have bikes setup manual fan switch and i have fan setup for thermo switch fan setup ....there both good setups ....with all the head gaskit trouble people have on such small heads it must be thatr the honda setup is just not good enough IMHO in adverse conditions ...my 79 has been around since new and has never had a head gaskit problem or problem of any kind except me ...i took a completely perfect running bike apart down to a baskit state and it been that a yr now and some oh2: :mrgreen: .....anyway i took the thermostat out when i was in fla and it was obvious it couldnt handle the fla heat and humidity in traffic it almost blew a head gaskit one day ...when i got it home and it cooled off i took the thermostat out and it was one of the best things i ever did to the 79 that was over a decade ago..... :mrgreen:

JD,

Well you know the saying "if it ain't one thing its three"

Just when I get the carb issue resolved the specter of overheating raises its ugly head.

I am hopin it was a fluke. One thing I did notice on my little ride. I had left #2 vac screw out of the intake runner after I pulled the sych fittings. I put the other three in but forgot this one. I rode it - and only noticed it just as I was about home. Didn't want to stop. I had no tools it was raining and I had the shelter off.

wondering if that caused a lean enough condition in that part of the motor to generate more heat.

As I said when I got home i let it sit for awhile (1/2hr) and checked the coolant - cool. Started and ran it again till it just kissed the 1/4 mark on the dial - less than 5min. checked it and it was warm so that suggests the thermostat is working too... No?

I am kicking myself now for not putting in a new one before I installed the motor. I did the belts, but just spaced out the thermostat.

I could def. feel more heat off the bike. Go figure my 78 ran very cool....

Is there a downside to taking out the thermostat?

 

[Pony Ruiz]

I'm up early as usual. checkin up on my forum buds.

As soon as I can I am going to start this puppy and do another ride around with the screw back in the intake. I am gong to stay a little closer to home this time though......

If that doesn't help matters on to a new thermostat. got the plug wires/caps so might put those on while I am at it.

gettin there.....

after that i need some advice on the front fork adjusters will post a new thread for that. :salute:

 

[dan filipi]

curious how it does on the ride.

 

[Pony Ruiz]

Running too hot - no doubt about it.

i rode around the neighborhood for less than 15min. By the time I got home it was pushin the half way mark on the gauge.

I am going to do the thermostat... for some reason the cup is half full on this one. Gut feeling - I don't think it is the thermostat, but I've been wrong many times......

After that? I have no idea. not getting oil? coolant is brand new... blackage somewhere?

anything else I should do while I am in there?

:crying: :crying: :crying:

 

[slabghost]

You might try flushing the radiator and check to see its clean and unblocked so air can get through it. You also have the option of running a restrictor plate in place of the thermostat. Do you have the side scoops on your radiator?

 

[dan filipi]

Did this problem just start, has it run cool before?

Check the coolant reservoir while running for any bubbles which could indicate a blown head gasket which will make the temp rise like that.

While you have the coolant drained, pull the water pump cover off then crank it without starting and look to see if the pump is turning.

 

[joedrum]

id still try the ride without the thermostat in pony ....you might find out that it runs cool as can be ....that will confirm its the thermostat period....if there is something else wrong your ride might last longer but it will still get hot .....one other thing on 1100s ...sometimes the 7 volt regulator will go out and the temp and gas guage will read on the high side as they will be on 12 volts .....causeing them to misread....

if it were me ...id take the termostat out ...put it back together start it in the garage or driveway ....put a box fan on the radiator and run it .....idleing ...if there is somthing wrong somewhere it will show up and still get hot ....thermostats are blockage its just nice to test its involment right off the bat ....if it dosnt get hot in this controled envirment ....then i would take it for a ride and see what happens there ....those darn thermostat bolts can be tough sometimes ...people tend to over tighten them...and the inside one is tough sometimes be patience and dont break it :mrgreen:

 

[Pony Ruiz]

the rad wings are off cause I have been working on the carbs. Its 50 friggin deg. out!

thought about the water pump, will check that.

I can't really tell if it just started I've only ridden the bike since I got the carbs dialed.

Before that it belonged to the PO. He gave up on it - the carbs. This is a diff. motor than what was in the bike when he had it.... less miles/more compression.

JD. I think I am going to take your advice. We'll see what happens.

[danf]

Let us know how it works out for ya, joe's a pretty smart dude...I get my belt covers off in about a minute now because of him just using one bolt instead of two, I just put a dummy bolt head in the inner hole's and JB Welded it in place..You would never know there wasn't an actual bolt there holding the cover... Can you imagine if some dude were to buy my bike then went to take off the belt covers, Surprise... :smilie_happy: the bolt falls off.... :smilie_happy: He would freak out I bet...

 

[Pony Ruiz]

wasn't the thermostat.

I took JD's advice and removed it from the loop. I rode around for 10min. that's it. Temp gauge moved to 1/4 scale then stayed there for about 5 min. then I ran/reved it a little(not much really) and 5 min later (around the neighborhood a couple times) it is up to 1/2 on the dial.

temperature sending unit maybe? Temperature gauge? Something blocked?
the radiator drained and flushed good.

coolant was warm to really warm. Opened the cap and stuck my finger in it after 5 min.

i swapped out the thermostat fan/switch for giggles, but I think I missed the connection - the fan didn't come on.. Going to double check that. Radiator has to come out again I guess for that. I have a spare/used temperature sending unit I am going to swap for the one that is in there at the same time. they both can't be bad. I suppose I could install new ones to eliminate these as a factor. Going to get a new radiator cap.

When I ran the bike with the cap off I didn't see the water circulating like you do on a car - does this happen with GL's?

water pump turns fine. 50/50 coolant to water ratio..

It can't be the head gasket - wouldn't I see smoke? - this wasn't listed as a symptom of overheating in the troubleshooting part of the shop manual - not saying it wouldn't be the case though.

Other than the overheating (hoping it is this: bad temp gauge / temp sending unit) bike runs good, has good power, accelerates good, Carbs are doing good .....

 

[joedrum]

okay pony ...idont think its the temperture sending unit ....halfway on the temp guage isnt that hot ....but if you didnt see flow in the radiator with the thermostat out then this isnt good ...or was it when you check that the thermostat was still in ....thats why i like to check things on the cooling system with no thermostat in them ....it flows the radiator at full output...right now ...so if you havnt check the flow with thermo out do so with the cap off and box fan on it at home .....

if its not flowing then things are not good....on rare occaisons the drive on the water pump can be broke ...the water pump is driven by the oil pump through a rod .....to check this after you find there is no flow ...just take the waterpump cover off and put the kill switch in the off possition and turn it over ...if the pump turns your okay here....if not this is an motor removal and motor spilt apart deal ....hoosier daddy had that happen to his bike after putting in unknown motor ...he recovered from it and his bike is top knotch personal build ...his bike is on our bike parade .....hopefuly this is not your problem....

now that the thermo is out stick the water hose in there and realy flush that motor

dont forget the guage might be reading wrong ...not because of the thermo sensor but because of the 7 volt regulator .......if your bike is an 83 interstate its in the instument cluster ....if its an aspy im not sure where it is ....ive had this happen to me when i first got my 82 ...it was registering hot but wasnt ....the gas guage registerd full at half full ....if you have a full tank you wounldnt know that it wrong....

keep calm pony and stay at it :mrgreen:

 

[toytender01]

I can't speak to your problem But I have riddem my 80 for 2 years and the temp gauge has always read 1/2 and at about 3/4 in stop and go situations the fan comes on and brings it back down. I think for my bile that is normal even when temps are over 100 degs. :Egyptian: :Egyptian:

 

[joedrum]

toy has a good point pony ...your used to the 1000 ....1100s run hotter than 1000 do there sleeves are bigger in the same block ...meaning less water around the sleeves for cooling off .....so make sure its actualy getting hot ...id do the run in the driveway thing with the box fan and just watch and learn what its doing :mrgreen:

 

[Pony Ruiz]

Toy, JD,

I did the run in the driveway. Ran for 5 min. with the box fan on it.

Temp got up to middle of the 1/4 mark.

I did see water moving in the radiator this time....kinda bubbled up and out a little - put the cap back on.

pump works - when I had the Rad off - cranked it and it spun like it should...

water is getting hot...felt it getting warm and felt the front of the rad (box fan on it) - warm.

dont forget the guage might be reading wrong ...not because of the thermo sensor but because of the 7 volt regulator

(I copy on the sending unit - it is reading temp. a bad one would go out completely or give a bad reading?)

This 7 volt issue has me wondering. Would this affect the gas gauge too? I looked in the gas tank. It was full and I've been running it - sitting and around. the gas is about an inch above the petcock. The gauge is reading just below the full line. Seems like it should read less.

I did see an upgrade for a regulator somewhere this https://www.ebay.com/itm/SHINDENGEN-MOSF ... es&vxp=mtr

how would this help me? What exactly is the issue with the 7 volt regulator. Bike is an 83 interstate. with standard speedo and tach.

If the gauges are accurate - and the bike runs a bit warmer than the 1000 I am ok with that. I just dont want to blow a h. gasket cause I thought everything was cool...no pun intended.

I am still feelin the love for this bike.....It is a good feeling knowing I found a prob. and fixed it.

Carbs are working - couldn't be happier about that.

Yeah I did the work but you guys provided the much needed support. I hope I can give it back somehow.

Muchas Gracias!
