20 Most Recent 1998 Honda CBR 600 F(3)W Questions & Answers

Check the compression. If it has low compression it will always be difficult to start. I have the same bike. It is a really good starter, comparatively to other older 'cycles I own. 1) Check the fuel level in the tank, and be sure to turn the fuel switch (left side of bike below tank and seat) to On, or even Reserve 2) In stock tuning, my bike likes full choke for cold start, in any ambient temperature, it likes to warm up with the choke on, until it starts to sputter from the rich mixture. 3) I believe this bike has vacuume tube that goes to the fuel petcock, this shuts off fuel to carbs when bike is not running. Thus if the bike has not run in a while, or the carbs drained, it will take several start attempts to get the carb float bowls filled. 4) This bike is hard to start if the battery is old or marginally charged. 5) Also pull the spark plugs, if they are brown, or black, change them. 6) check the air cleaner, if it is too dirty it will essentially act like a choke

When you say that you cleaned the carbies, did you remove all of the jets and inspect them? I have had an issue with long storage where some corrosion took place inside the jets and blocked them. The only solution was new jets. Also, stale fuel can block up some of the finer arteries by turning into 'jelly'. Look at the link attached =] How to clean the carburator CBR Forum Enthusiast forums for Honda CBR...

I would think about investing in a carb re-build kit.

when does it happen ? choke on or off / while riding or in neutral ? ... as a first guess i would say the throttle should be adjusted...

If you do not know this then I recommend getting a workshop manual before doing any maintenance. Oh...its 4.

Possibilities are: mount screws need to be tightened, tank is rusted through, cracked pump casing and bad fuel line connection.

hi would be good idear to also check spark and and timing also if you just got bike give it a good service this includes fuel filter

hope this helps

I would suspect a faulty ground in this case. I have not had this happen to me but that is what i would be looking for in your case.

If you park outside or live in a humid or salty area like I do, then I've found it can really help to split the switch gear open (be careful not to let anything fall out), clean every contact surface you can find and then spray everything with WD40 or Tri-Flow to displace any moisture and inhibit corrosion. I've owned a lot of Hondas over the years and had almost every switch stop working at one point or another and this almost always stops the problem. Plus an f3 is just abou the right age for this to start happening. If it doesn't work then you probably have a short (which would be odd for a Honda unless its been crashed or modified.

have u made sure the floats have not got stuck

There is a special plug wrench for this. The socket is very thin and narrowly fits in the hole. The plug cap has a rubber grommet that seals the tube.

If you look on each plug lead, there should be a number 1, 2, 3 4.

Put them onto the relevant cylinders . !

It's not the seal that's expanding, it's the metal. In any case, you will need to put a new seal/ o rings in.

put a volt meter across the battery, engine stopped must be over 12v.
rev the engine to 3-4000 should rise to about 14v, this will show the charge system is working
Some batteries only last 12 months or so. if it is a couple of years old buy a new one, the gel ones seem to last longer

The handle of the petcock should be pointed up.

The Bike Technicians Tactic

Phase1

An electrical inspection on the bike should produce results. First, the bike battery powers the entire lightening systems mentionable as ignition, meter readings, head lamps, signal indicators. However, the battery provides the power supply to several entities though also significant is the fuse box containing circuit protection coils. Inserting the bike key into the ignition to perform start mode displays the capacity power circuits. A charged battery should display an indication in the meter reading area also known as bike dashboard grading. A malfunctioning start mode on inserting key in ignition may be traceable several locations on the electrical circuits. Attempting to repair the electrical power of the bike usually requires batter power power test kit. The test kit ascertains the battery power making possible progress to the remaining electrical circuits. Test kit also ascertains the fuse box circuit functionality either with fuses still intact or extracted allowing for the next progress level. An observation tour of the bikes electrical wiring kits from battery hold through fuse box compartments to each lightening display area either headlamps, indicators, and meter reading should produce results of any visible damages that may require repairs after the electrical inspection has been performed. Once any faults were observed on the electrical channels, repair mode is the next level. A dull battery either may have been depleted completely of durational capacity requiring another for replacement. Alternately, a depleted power supply due to prolonged storage may require charge functionalities. Usually, a device capacapble of restoring a battery of electrolytes is resorted for charger ability. The type of battery may require constuents either liquid cathode replenishment in the battery entrapment area prior to charging feature is assumed with electrolyte machine. Once the battery has regained full functionality makes way the next repair task. The fuse box may have simply required replacement fuses either as missing or burnt out. A fuse box usually contains additional spare for replacement functionalities. An alternate arrangement at acquiring fuses on the auto mart may replace the burnt devices. The next electrical task is wiring fixtures achievable by mending broken cords with appropriate electrician's tapes else malfunctions may remain. Alternately, a worn-out electrical wire is replaceable by acquiring the entire extension lengthwise between significant areas. The last remaining electrical units are lightening indicators consisting of bulbs or luminescent displays reflectors. Observe the blub areas either by loosening covers to inspect for observable burnouts else the entire electrical circuitry is ready for functionality observations with separate entities.

PHASE 2

A bike engine inspection includes observation for indications of malfunction. Any fluid residue is indication of problem areas. Where oil leaks usually requires engine block inspections. A bike engine consists of an entrapment compartment where mechanical combustion takes place. First, the entire observable block consists of an external coating known as engine bloc housing internal component of pistons, rings, and fastens known as cylinder heads. A bike engine has every component embedded within requiring technical expertise to achieve an inspection. Once deciding on the engine task requirements, acquire a tool box with the appropriate componements as first requirement before engine works is commence able. Second, the bike may require an area environment as workshop requirement to attain engine inspections. Third, bike engine are least bulky compared with vehicle engines however assistance would complement the inspection phase. Prior to inspecting the bike engine, a strap mechanism has to be assumed to achieve expert maneuverability also as safe precaution. Unless parts hinder maneuverability at engine locations, the only removable components should be the engine. First, start with disjointing the spark plug cables to acquire accessibility to plugs imbedded on the cylinder heads. The plugs require tools to loosen thereby exposing the combustible area. Once the spark plugs are exposed, two alternatives are likely. First, a spark plug may have gathered rust residue only requiring cleaning to attain regular capacity. The pin area of the spark plug may have been twisted due to overheating and slight melting dislocation. Usually cleaning the residue from old plugs may simply expose the ignitable capacities. However, an observation of twisted plug pin may require twisting back in place to achieve full ignitability once bike engine starts. A bike engine bloc has the pistons as combustibles or blasters of fuel gasoline. The rings perform as strap fasteners whenever the pistons move about combustibility. Usually, the engine entrapment components would have collected residue requiring clearing. Also, pistons together with rings may require replacements either as worn-out due to prolongs tasks or overexerted biker features.

There isn't one. The cooler has the oil filter attached to it. When you drain the oil and change the filter, the cooler emties as one changes the oils and filter.
Hope that helps.
