1998 Honda CBR 900 RR Fireblade - Answered Questions & Fixed issues
Hi,how can i check that my coolant fan is working
the fan wont cut in till the engine is very hot,,, well over 100 degrees near to 120! if you realy wont to test the fan out pull the bike up on its stand and leave it ticking over,,, it should take forever before the fan kicks in,,,my bmw has only ever switched the cooling fan on once in 3 years!!!! and that was after standing with the motor running in a traffic jam for 35 minuets !!! but if you wont to find the temp switch pull the plug off the switch and short the two plug pins out with some wire that will start the fan up,,,watch your fingers,,,you only get 5 free fingers on each hand with each body,, and there are no spare parts going cheep?
My Honda Fireblade will not start?
Hi and welcome to FixYa,
Initially, confirm presence and consistency of spark on the plug ends when cranking. Thereafter check for fuel reaching inside the cylinders by cranking with sparkplugs in place but not HT wires connected. Remove the plugs and note for presence of fuel.
Perform above spark and fuel tests; postback results.
Note: Almost always, the carbs has to be pulled out for a complete cleanup. The old gasoline could have turned to varnish like substance and coated the ports, jets, passage ways and carb bowl/walls.
Good luck and thank you for using FixYa.
Jerking at low speeds.
Probably a blocked low speed jet / jets in one or more carbs you can try a fuel additive(cleaner) but probably won't work, the whole lot should be removed and cleansed not really recommended for the DIY guy
Changed ignition on my CBR900RRW today yet no
There is a good chance that the "Hotwiring" has caused a failure of either the immobiliser or the ECU. The only way to be certain which is to replace them one at a time or to get them tested at a Honda dealers.
The battery is not charging
Its either a bad stator or rectifier. Most likely it will be the rectifier that went bad. I've had that happen last year. You can get one off ebay for 25 - 80, I suggest changing over to one of the newer designs with the cooling fins. The rectifier is located behind the rear side fairing, above the exhaust, on the frame near the battery.
My 1998 cbr rr honda motorcycle battery is not charging
Do you own a volt meter?Get a voltage reading from the battery while the bike is off (the resting voltage). A short cell should prevent you from ever reading anything more then 10.5 volts. If the battery is 12.2 volts or less, it's discharged. Fully charged is 12.8 volts. Next, start the bike (or jump start it if the battery is down) and take a voltage reading while the bike is on. The Voltage should go as high as 14.8 volts. That's normal. If the battery is down, it will have to climb up to that point. I got this info from
here.
When engins is running, fuel
Sounds like you need to replace the fuel hose or connectors from the tank as fuel will only flow through them when engine running as the tap is vacuum operated.
Can i adjust my timing
no, there is already a part that will tighten your timing chain we called it chain tensioner. if your chain is loose you better change no need to adjust. thanks!
How do I remove the
The battery is located under the seat of your bike just remove the seat and remove the battery.
3Does Honda sell a rebuild
No Honda does not sell a rebuild kit. Honda only sells assemblies. The petcock is pressed together and therefore can can not be disassembled and reassembled to replace parts.The main valve from Honda runs about $175. The vacuum diaphragm assembly, if this is the only thing leaking, can be had for around $40.
Oil coming throught the rocker
check your crank breather, to much block pressure will keep the oil on the top end,not allowing gravity to do it's job, maybe??
What's the best choice for
For most riders the standard (hotter CR8EH-9) spark plug is the best choice. Most cycles are set up for sea level running and on the rich side for longevity of the motor. As you move higher in elevation the thinner air makes the cycle run even richer. Vacuum carburetors and EFI systems on Honda's compensate for most of this , but a colder plug can be progressively more prone to fouling under these conditions. If warm temperature, long distance, and high speed running (combined) is your style of riding, then the colder plug (CR9EH-9) is probably a good choice for you. I do a lot of long distance riding in the heat of summer and have never felt the need of the cooler plug. I do recommend that you carry a second set of plugs in either case, just in case you foul a spark plug (I carry my old plugs that still work). The plugs you use may not be readily available unless the rare fouling of a plug just happens to be next to a Honda dealer. There is a relationship between temperature and plug heat range. If you had a sidecar and liked to drive around in 30 degrees F you might find the cycle started better with a CR7EH-9 (At 100 degrees F you would probably melt a hole in your piston with the CR7EH-9 installed).
