Title: Looking at buying an '02. Need some advice
Post by: Brentos on August 07, 2019, 12:52:17 am
Hi, I have my eye on an 02 with 37k miles on it.  It has a broken pilot screw(?)  I believe that is what it is called.  The black plastic adjustment screw on the bottom of the quad carb assembly.  It will not start, it turns over fine but spits once and continues to turn over without firing.  The guy selling it says that it ran fine until the adjustment screw broke.  I have been reading as much as I can on this forum and have learned about hydrolock and other concerns (odd tire requirements,  ethanol is bad, and how Steve in Sunny Florida is the guru of the Connie).  The bike has been sitting for one year, when I checked it out there were no leaks to speak of, a little oil on the bottom of the drive where it connects to the rear wheel but the seal seemed like it was not dried out or cracking.  All of the hoses I could reach were pliable and the wires I could reach seemed in good shape.  So with that background here's my question: 
What all maintenance should I expect with a Conours that has sat for a year to make it safe.  It has new plugs, spark wires, and battery.   It obviously needs new tires, oil, coolant flush, brakes look pretty good, the suspension seems like it needs adjusting (read a little on that here), the tank lock is broken so I'm figuring drain and flush check the petcock, have to remove it anyway to remove the carbs, fix the adjustment screw needle assembly.  In the process clean out the carbs of any gunk that has accumulated, and sync them.  What else should I look for?  Im trying to determine if I am buying into a sinking ship or what.  Also my knowledge of how to sync the carbs is from a Youtube video I found other than doing it by eye and then tuning them in with the bike running what special tools make it easier.   Im pretty mechanical no machinist but I like to wrench.  Am I dreaming here or is this pretty doable in my own garage? 
Thanks in advance for any and all suggestions, 
Noob.
Brent

Black plastic screw? Do you mean the idle adjustment knob? The pilot screws should be brass and are hard to get to with the carbs on the bike. If it sat for a year without treating the gasoline, I would almost bet money the carbs are gummed up. Especially the pilot jets.

Yes it must be the idle adjustment.  Its a black plastic knob.  The replacement has a cable attached that ends with a pointed brass pin.

When the pilot jets clog up, the bike won't idle very well, because it's lean. That's a telltale sign if the idle adjuster is maxed out from the owner trying to get it to idle. In this case, he turned it too much and broke it. So, count on the carbs needing cleaned and rebuilt. You really should get the overflow tubes installed by SISF too.

Your information on the bike is limited. A non-running bike is a salvage bike.

If you are going in blind, then it all depends on the price.

For the right price it can be a gem or a lead weight around your head.

Choose wisely.

How much is the seller asking for it?

It depends on how mechanically inclined you are. If you have to pay dealer prices for all the work then free may be too much for the bike. Like wise if you need it to be running next week. A project bike that you can take your time with and you are willing to do the work, ok.

A good running C-10 can be found for south of $2000.00, maybe even with a lot of accessories.

This where you either take a chance or ask him to let you do a hydrolock test. (which he probably wont seeing some things have to be taken apart)
  It does sound like carb work is in order so you have to be careful on the buying price.  A non running bike should be cheap .

He's asking $500
Title: Re: Looking at buying an '02. Need some advice
Post by: connie_rider on August 07, 2019, 02:10:51 pm
$500 would be pretty fair.

As the idle screw is damaged, it's probable that he screwed it in al the way to get the bike to idle.
 This is an indication of stopped up pilot {or other} jets. A carb rebuild would cure this....

 There is a chance that the bike was hydrolocked. Hydrolock can result in a bent rod.
   This happens if the floats allow excessive fuel to flow before the engine is cranked.
 
  Turn the petcock to prime at let it set. See if you begin to smell or see gas at the carbs.
    If no {and if there is gas in the tank??}
   Question the seller and ask if it ever did hard knock when he was cranking it.

If anything points to a hydrolock, either take a chance, and/or walk away...

If the key is broken in the gas tank cap, removing the screws around the cap might make it possible to get the cap off for replacement. Possible a lock smith could get it to open as well.
Aftermarket (or used}T) replacement caps are pretty inexpensive.

Ride safe, Ted

$500 may be OK. But I wouldn't buy it. As you can see below, spend another 500 and get what seems to be a great bike. Why bother with a non-running bike. Your inspection is very limited.

I'd buy your salvage 2002 for $100 shipped.

The guy selling it says that it ran fine until the adjustment screw broke.

Yeah, right.  Famous last words.  Reality is it was probably running like crap and he was trying to keep it running by turning the idle adjustment screw until he broke it and gave up.  Carbs will need to be gone through, which is $500 unless you do them yourself.  So right there you're into the bike for $1k if you give him his asking price.

I agree with DC - forget the '02 POS and jump all over the '01 for sale in TN for a grand.  Better hurry though - that bike will not last.

If the pilot jets are clogged, sometimes it'll run if you use a lot of choke (not full choke, just more than normal). Hard starting is another indication and if you do get it started, it'll idle rough and will die with the choke off unless you give it some throttle.

I'm in Alabama.

Ha a bro from Bama.    Im from just south of Huntsville.
 Back to the bike. This is a hard one without standing in front of it. We cant say anything about the condition. Other than it dont run.
  500 is not a bad price . maybe you can get him to go lower maybe not.
 If you feel like taking a chance and working on it youll get a lot of help here. The trick is to not put too much into it. While these are great bike and well loved here . the value is pretty low . I have a friend here with a 98 ready to ride coast to coast that can be bought very reasonably . Or the one DC pointed out looks like a fair deal too.

I’m in LA. Lincoln Alabama myself,    Don’t be scared of a higher mileage bike,  most of the time someone stayed on top of the maintenance,   My 1994. Has 73000.  I’d take her anywhere.

1st. time user. Hope it's ok if I join ongoing conversation? All of the info in this conversation is applicable to me, with one exception. My O2 ran great! I'm a disabled vet, traumatic brain injuries affected my balance and I just couldn't handle the bike at that point. I want to get back to riding ASAP, pretty sure I have rewired my brain sufficiently. My bike has been sitting for 2 years, but as I said it was running great when I last rode it. Would I be safe draining old gas, filling up with a gallon fresh fuel and trying to crank it over? Hydrolock scares me. If my carbs are gunked up and I try to start am I risking hydrolock? Guy I bought the bike from was a good mechanic with attention to detail, I could tell that just visiting his shop. Tires are 4 years old with plenty of tread left, should I replace them anyway? I intend to change oil, filters, Lube drain and refill radiator. I apologize if this sounds a bit confused, I am! :-)  fingers are still pretty stupid and my voice recognition software sucks. Thanks for your patience.

Welcome and you should start a new thread.

I would recommend that you change out ALL the fluids and see if there is any fuel leak after letting it sit overnight on the kickstand. You have read all about hydro locks so I won't go into that here.

How was it stored when you stopped riding it? You will likely need the carbs cleaned.

Tires may be fine if it was stored in a garage but rubber does get hard/crack and don't grip after a while. you need to check for that.
