Carbs or airbox is suspect, maybe more.

How did it ride with just the fuel filter off? If you aren't already, you might want to test it one change at a time to ensure you find the right issue.

Oh yeah, still not riding it anywhere yet. I thought that the absence of the fuel filter would magically let it turn on, but to no avail, *sigh*

It still tries turning over really strong and the battery is charging at 12.75 volts, so I don't think that it's the battery. The fuel filter is gone so it's not that. I checked the pet-cock so it isn't that either. Hehe, narrowing it down at least. I'm checking the coils, the r/r and stator tomorrow and we'll go from there.

Tomorrow I'll try testing the things I mentioned. I have been doing it methodically, testing it each time. Still nothing, so that's where I am so far; where I was at the beginning of the thread. Not really though, because I have crossed a few items from the list of things it could be.

Tomorrow is another day and I will get this problem yet.

Did you check the spark plugs for fouling? That would indicate richness or weak ignition.
If they are white that could indicate air leak or fuel starvation.

The thought hadn't occured to me. I will put that on the list of things to do today. Thanks Chef, I guess you saw my post in the rally thread.

One more easy thing to check, is the tank venting properly? Just open the gas cap, if it instantly runs better that's your problem

Can you get to the fuel bowl drain plugs? Open them up and see if there is fuel in the bowls.

I second the coil idea. My bike would run fine for 15ish minutes and then start to bog down and eventually just fail. I stumped me though because if I let it sit for an hour it was start back up fine like nothing had happened. I had tested the coils before riding and they would pass every time. However, after riding (and I didn't realize this until later) the coils would get REALLY hot and fail. I replaced them with the Dynatec green coils (3 ohm) and did the horn relay mod on basscliff's site and wala; all was good in the world

Hi Mr. frijoles-and-beans,

So where are you in your troubleshooting? Do you have good spark? Have you replaced the plug caps? Have you tested the coils? You should get 3-5 ohms across the primary (the little input wires) and somewhere around 30K ohms across the secondary (the spark plug wires) on each coil. Yes, just stick your ohmmeter in the #2 and #3 spark plug caps and measure the resistance. Then do the same for #1 and #4. Have you replaced the intake boot O-rings? Have you tested your petcock?

Sorry, all I have are questions. I hope you can get this cleared up in time for our big weekend.


Thank you for your indulgence,

BassCliff

Ok, I've checked the spark. All four wires are putting out spark. I've checked if the tank was venting properly; it is. I checked the plugs. They are in very nice condition.

All this makes me wonder if it's the charging system. I will check it tommorow; the stator and r/r. I will also check the coils' resistance. I didn't have time today until this evening. I will have more time tomorrow.

Hmm, I was hoping that tkent02's suggestion about the bad vent would work; darn.

Basscliff, I have a set of carb boot o-rings on order, but they won't arrive until next week. I really hope that I can make it to the rally. Thanks for taking the time to come see me about my little dilemma. At this point I hope it's the coils so I can at least have a cause and just get down to fixing it. They delivered a good spark so I'm doubting it, but I haven't seen any numbers yet so I'll see what happens tomorrow.

I have orings and a garage.

I hope you get it sorted out for the rally.

I have the sneaky feeling from reading some of the responses that you guys think that my bike actually starts and moves forward. It doesn't yet. It doesn't start at all. Maybe I'm bad at explaining myself. I'm outside and about to check on things. Update in a little bit.

[Charlie G]

Well any hope of getting it fixed?

I've been cleaning up connections and think it might be the coils. The tests ran within normal parameters though, but I have a feeling that it's a weak set of coils that I'm running so still nothing. I hear those Dyna S or whatever I've heard them called here are a good upgrade. I'll look up the name. It's in some thread or other, probably in a few.

Looks like I'll be missing the rally this time Charlie G. I'll go for sure next time.

I'm going to put some new carb boot o-rings on too while I'm at it.

[hikermikem]

I only offer the following suggestions because it's something I've had happen to me before:

- Enough fuel in the tank?? (sometimes it sounds like there's plenty sloshing around when there isn't...)

- Kill switch enabled?

Mine absolutely will not start without some choke or full choke. That's even after having been on the road for awhile. I know that's due to the primary circuit being partially restricted somehow and I haven't had the time to clean it out yet. You may still have something that made it's way through the fuel system causing the problem. Choke it and see if you can get the plugs wet with fuel while you're cranking it. If not, it's still in carburetion.
