20 Most Recent 2001 CCM 604 RS Roadster Questions & Answers

10W40 is standard. 5W40 is o.k. too. You can change the type but mixing different types is forbidden for some reason. One figure is for fluidity and the other one for temperature rating in extreme conditions. Ask a mechanic.

is the barrel surface ok ? if they did the total job then its down to them !! citizen advice people should be able to help also !

aint a hundred per cent on this on but if you reversed the + - wires to the starter would it not turn the correct way???

just looking for wheels now. I can turn spacers if need be but if discs/sprockets don't match I'll be stuffed.The hubs and bearing sizes are the same but either could be made by AJP or Talon. Some handy things to know are ; 604 sprocket is no good for a 644 unless a 520 chain has been fitted. You will need to turn the rear tyre round if the wheell was on a 604 and its to go on a 644. Talon hubs use a different speedo drive to the AJP,,,

Manual gearbox I assume. A similar thing happened to me. Tho problem was faulty clutch. The clutch did not open. Probably a work shop job.

It could be the starter gear is gone.

I think this may be another one of those faults due to the ethanol and other **** in modern fuels. There is so much rubbish in petrol the stuff just wont keep also ther have been a lot of problems with the stuff rotting fuel lines this may be your problem, the float needle may be getting stuck by particles of fuel line.

Flooding carbs often means that the needle valve that the float is supposed to close is leaking, causing the float chamber to overflow. replace needle valves.

Some common causes and potential solutions: Air/Vacuum Leak: If your Harley develops a vacuum leak in its air intake system, the air-fuel mixture becomes too rich. This can cause frequent stall outs, especially after the bike warms up. Vacuum leaks often occur due to dried-out or cracked air intake boots, faulty gaskets, or worn-out carburetor seals. When air escapes from the intake system, the fuel fills the empty space in the combustion chamber, altering the air/fuel ratio and negatively impacting combustion. Severe vacuum leaks can lead to excess fuel flowing into the exhaust system, causing backfiring and stalling while riding. Clogged Fuel Tank Filter/Fuel Injectors: A blocked fuel tank filter (due to coagulated fuel, moisture, dirt, or corrosion) impairs fuel flow, resulting in a lean air/fuel ratio. On fuel-injected Harleys, clogged fuel injectors produce similar symptoms. Regular maintenance, including cleaning and inspecting fuel filters, helps prevent these issues. Faulty Cam Chain Tensioner: A malfunctioning cam chain tensioner can affect engine timing and cause stalling. Regular checks and replacements are essential to avoid this problem. Faulty Cam Position Sensor: The cam position sensor plays a crucial role in ignition timing. If it malfunctions, it can lead to stalling and backfiring. Clogged Air Cleaner: A dirty air cleaner restricts airflow, affecting combustion efficiency. Regularly clean or replace the air filter to prevent this issue. Ignition System Failure: Faulty ignition components (such as spark plugs, ignition coils, or wires) can cause misfires, backfires, and stalling. Inspect and maintain these parts regularly. Compromised Battery Terminal Connection: Poor battery connections can disrupt electrical flow, affecting the ignition system. Ensure clean and secure battery terminals. Remember that diagnosing and addressing these issues may require professional assistance. Regular maintenance and timely repairs can keep your Fat Boy running smoothly on the road.
