Question about Honda Motorcycles

1 Answer

I have a honda EX5 (GN5 engine) which is single cylinder and single cam.. the problem is,it's suddenly start to sputter after a ride in a heavy rain.. the idle is a little slack on it,sometimes it sounds like it having wrong camshaft mark..( well , it would've show the symptom if it's run off the mark)..I thought it was the chain slack..so I just rebuilt the whole thing, change the camshaft,chain,chain roller and chain tensioner. Also I check the spark,but its seems fine.. I wonder what caused this? Could it be a premature CDI failure? Because i thought it would misfire because it sputter and giving a slack idling even running rough..

Hi, Saisoku this happens to a lot of bikes and different brands it is usually caused by water getting into the fuel system and/or moisture getting to electronic components, wire connectors, wiring harness. This situation usually clears itself by letting the bike sit for a couple of days in the sun. For more information about your question please click on the blue links below. Good luck and have a wonderful day.

You may have a bad coil pack - try moving two of them around and see if the misfire follows the coil pack or stays at the same cylinder. If it follows the coil pack, get a new one. If it stays in the same cylinder, inspect your spark plug wires and make sure the plug is gapped correctly.

SOURCE: 1999 Town Car began running very rough - suddenly.

When cleaning your engine, water/degreaser went down the spark plug ports. Try using a air compressor blow gun to remove the moisture from around the spark plugs and boots. The water was causing the engine to misfire on 3 cylinders at first and as the ports started to evaporate the moisture, the less misfiring was occuring. Dry thouroughly and hopefully coils do not have damage to them. Also check to make sure the boot is making good contact with the spark plug.

Check the ignition control module. Sounds like the exact same problem I have had with mine. Took it to the dealership and the were able to tell me right away. The ignition control module is very easy to replace and is located on the top of the valve cover. Hope this helps!

Check for

vacuum leaks on intake manifold,

the air tube between the air filter.

intake manifold vacuum hose.

===
clean throttle plate with Berryman carburator cleaner

SEE sample picture HERE
===

Also remove carbon built up behind the EGR valve and the EGR passage tube.

===

Vacuum leak WILL offset the intended 14.7 to 1 air fuel ratio.

More un-metered air (leaks) will lean out the fuel mixture.

Use small amount of Berryman carb clearer at potential air leak area will help you identify trouble spot.

At idle,just spray and listen for the RPM surge.

The in-rush of carb clearer will increase the RPM on the motor.

Record the problem spot(s) and address it later.

===

EGR carbon built up require 2+ hours to clean from start to finish.

You will need a new EGR base gasket before your start.

Locate and remove the EGR valve after the vehicle is cool down.

Carefully record the connector and vacuum line (for older vehicle) location by drawing an easily to follow diagram.

Remove the EGR valve.

Inspect the location of the carbon built-up inside the valve and the EGR passage tube.

SOAK these areas with WD-40 spary.

You will need a small screwdriver,cloth hanger and lot of newspaper and time to get this cleaning done right.

RE-SOAK the carbon and let it sit for over-night will also help.

One the last round,pass a shop vacuum of the EGR valve and the passage pipe.

Install the new EGR gasket and connectors.

Allow the vehicle to warm up outdoor to burn up any remaining WD-40.


Take it for a test drive.

My dodge caravan is overheating and sputtering all the sudden. why?


definitely check ur coolant level. it might b empty /and or a hose leaking onto ur coilpaks or sparkplug wires causing a misfire or sputter. also check ur engine codes to single out faulty cylinders. if ur coolant level is fine u could possibly have a stuck thermostat not allowing flow. also dont forget to check cooling fan operation...just some obvious pointers u need to look at. good luck hopes this helps

Check your sparkplugs to determine if it is a single cylinder or random cylinder when the miss occurs. If it is a single cylinder, the sparkplug may have failed.

More likely to be your ignition coils. They heat up and expand this can cause an open circuit which will close up again when it has cooled down. Although, a bad charging system may cause this problem. Check the battery voltage with engine switched off ( approx 12 volts) and with the engine running (approx 14 volts) If you are getting 14 volts then your battery is dead, if you aren't, then your charging system has a fault.

Ignition components are getting wet. Check your ignition wires for leakage alobg their length and at the boots. You can do this with no lights at night with the engine running any leakage will appear as a spark. Some dielectric greas in the boots might also hel to keep the water out.

1994 s10 truck has spark and fuel but will not start This all happened suddenly no warning signs


Hi, An engine that has fuel and spark, no serious vacuum leaks and cranks normally should start. The problem is compression 57f07a7.jpg If it is an overhead cam engine with a rubber timing belt, a broken timing belt a35cd82.jpg would be the most likely cause especially if the engine has a lot of miles on it. Most OEMs recommend replacing the OHC timing belt every 60,000 miles for preventative maintenance, but many belts are never changed. Eventually they break, and when they do the engine stops dead in its tracks. And in engines that lack sufficient valve-to-piston clearance as many import engines and some domestic engines do, it also causes extensive damage (bent valves and valvetrain components & sometimes cracked pistons). Overhead cams can also bind and break if the head warps due to severe overheating, or the cam bearings are starved for lubrication. A cam seizure may occur during a subzero cold start if the oil in the crankcase is too thick and is slow to reach the cam (a good reason for using 5W-20 or 5W-30 for winter driving). High rpm cam failure can occur if the oil level is low or the oil is long overdue for a change. With high mileage pushrod engines, the timing chain may have broken or slipped. Either type of problem can be diagnosed by doing a compression check and/or removing a valve cover and watching for valve movement when the engine is cranked. A blown head gasket 1e00f0b.gifmay prevent an engine from starting if the engine is a four cylinder with two dead cylinders. But most six or eight cylinder engines will sputter to life and run roughly even with a blown gasket. The gasket can, however, allow coolant to leak into the cylinder and hydrolock the engine.
Take care
