Question about Harley Davidson FLHT Electra Glide Standard Motorcycles

1 Answer

One cylinder running only

I have a 1995 FLHTCU, when running it is only running on the front cylinder. The exhaust for the rear cylinder is cold, unlike the hot exhaust coming from the front running cylinder. I am getting spark to the rear cylinder. Also swapped spark plugs, with no changes. Need Help.

Check the cam lobes,valve springs, the valves them selves especialy the inlet, without looking if its a push rod or chain, but check the cam shaft mechanism ie chain

First you'll need to get a jet kit from West coast star. Then you'll need to jet the carbs to run equally. This may take some trial and error. Another thing that worked on my bike was the upgraded coil kit they sell. It's almost double the voltage of the stock coils and comes with better insulated wires for a more uniform resistance. I haven't had this problem since. It'll make the cylinders fire evenly and save you from those pestiferous fouled plugs. I hope this helps.

Not too hard - Undo the two bolts on the caliper and then seperate the caliper and pull the old ones out. Insert the new ones and put the bolts back in to hold the caliper back together and then install them back on the bike with the two retaining bolts. Use a bit of lock tight (Blue) on the threads. Warning do not let anyone apply pressure on the brakes while you have them off the bike or you will have a mess and/or a problem.

hi your carbs need rebuilt if you bought the bike with the cobra pipes on it an aftermarket jet kit has already been installed after time the aftermarket needles wear out and or wear out the emulsion tubes. i had the exact problem tried every thing coils, igniter box etc. check out GMAN INDUSTRIES. COM they will solve your problem. or sell you genuine mikuni parts with the correct jets, pilot screws, and needles.

I have a 93 sportster 1200 thats kinda hard to start dosent want to idll

On pretty much ALL Harley's (and all other air cooled V-Twins), the rear cylinder runs hotter because the front cylinder tends to semi-block the airflow coming to it.

You have only one carb, so if it was jetted right for one cylinder, the other cylinder wouldn't be too far off.

Most likely from your description (rear cylinder quits how ever at above 1700 rpms, sputters from time to time on rear cylinder, rear plug is a lot cleaner than front one), I would look at an air leak (common on Harley's) where the intake manifold joins the rear cylinder head, and/or an exhaust leak at the rear pipe.

Hi Anonymous, you could have rear master cylinder issues, the piston is not returning all the way, or a piston in the caliper is not retracting fully for what ever for what ever reason. Good luck

1200 sportster not running on back cylinder

Verify the cylinder is not firing by measuring the temperature on the exhaust right out of the cylinder. If it is not firing the tempature will be much cooler than the front cylinder. Once you have determined the rear cylinder is not firing then you need to perform a compression test on the rear cylinder. If it is not with in specifications, you may have broken rings, burned valves or hole in piston. Until you run compression test you will not know which way to go.

Bike runs but back fires through exhaust and intake. rear exhaust pipe is turning blued, while front is fine

You didn't say what year or model bike it is but I would guess, and that's all this is, that the rear cylinder is running lean for some reason. You may have an intake vacuum leak sucking air into the rear cylinder. That's my best guess.

Good Luck

On my pipes one side is hot and the other is cold

Check the pipe right where they come out of the heads. It depends on what type of exhaust system you have on your Road King. If the stock exhaust is on the bike, the rear cylinder exhaust is directed to both mufflers. With the exhaust from the front and part of the exhaust from the rear cylinders going to the right side muffler, it gets more exhaust than the left side and runs hotter. Like I said, check the temp of the exhaust pipes at the cylinder heads. If one of them is cold, that cylinder is not firing. As long as both of the pipes are hot there, you're fine. Just ride the bike and have fun.

Ride Safe.

Front cylinder misfire at idle,then raise rpm's to 2000 area an it comes in an out popping thru exhaust.front cylinder cold to the touch when rear is hot, till it runs a couple of min. New plugs, good...

I am not sure if the bike is a 650 or 1100 but in either case it sounds like a fuel issue or and air leak. When the carbs were off for re-jetting did they get cleaned? The slow circuit controls to about 2000 rpm and it sounds similar to your problem.

The first thing to look at is the carb synchronization. If the front cylinder is lagging, it can give the same symptoms. I do not think that the exhaust is a factor because the front is cold when running.

Spray some WD 40 at all the intake manifold area when the bike is running and see if the idle changes. the idle will change and push some smoke out of the exhast if the intake is leaking.

If both of these check good I would pull the carbs back off and clean the slow circuits out completely. This is delicate work and shoud be done by and experienced tech.

If I can help some more just send message.

I hope that his helps. Steve

How do you time a 1995 600 ninja

Turn the engine over by using a 17mm socket or spanner on the crank until the no.1 inlet valve goes down & then comes back up; continue turning until the T mark for cylinders 1:4 lines up with the rear mating surface of the 2 crankcases, number 1 cylinder is now at top dead center on the compression stroke.
The cams are marked 117 IN & 117 EX so they don't get mixed up, align the IN & EX marks on each sprocket with the the cylinder head surface so that the IN marks face to the rear & the EX marks face to the front.
Next check the no of roller pins in the cam-chain between the inlet cams IN mark & the Exhaust cams EX marks, make sure that all the slack is taken up on the rear run & that there is none at the front or between the camshafts: There must be 30 pins in between the 2 marks (including the ones next to each mark)
If everything is still the same when you have the camshafts bolted down you are OK

Ride safe
Please mark this as very helpful (if it has been!!) - it helps my ratings

When running, the front cylinder is cold and the back cylinder is warm. what does that mean. i bought a 1990 hd fxr. hardly any compression coming from front cylinder exhaust.

Check your compression at the plug .front cylinders get more air so are cooler the rear is always hot due to lack of direct air flow and get hot air passing over the fins from the front cylinder.
