20 Most Recent 1987 Honda CBR 1000 F Questions & Answers

The question I have is, does the headlamp get supply from the same place as the ignition switch? If it does, chase the cable back to find the break or you can cheat and run a fresh cable from the battery fuse to the ignition switch. That would prove the theory.
Hope that helps.

Sounds like the slides on the carbs are sticking. When the engine is under a load it draws a lot more vacuum that just sitting & blipping the throttle...Lube your cables, check throttle stops, and check for vacuum leaks around the carb boots...would be the areas to first inspect. I hope this helps.

chance is something is loose and as the engine warms up it takes up the slack due to the metals expanding, try to track the location of the noise. this is an older bike and internal components may be worn out, and until oil gets there and engine warms up this would be normal. try using oil for high milage engines and some slick 50 treatment if you dont find anything loose. (like engine mounts, pipe mounts etc)

make sure your not looking at the 600 specs ? i know you are smarter than that but that all i got ... let me know what u find

the 1987 and 1988 had 3 adjustment 1 2 3 or soft ride a medium ride or rigid sports ride. i dont know if the 93 has the same setting but it should be the same idea high being sport low soft or touring hope this helps

check your idle jets it right behind the main jet remove and try to blow through it clean or replace around 15.dollars each . also check main needle valve make sure it not sticking and that its smooth hope this helps

try changing the high low beam switch

The fuse is on the starter relay switch near the right side of the battery box

sounds like a fuel flow problem to me open the fuel drain screws on those inner carbs and see if there is fuel in bowls

make sure it is sparking at tdc on the right sequence, also put all new jets and soak the carbs

check pulse generators first, i found one burnt and one was open on my 87 hurricane 600. Ohm the wires out for opens or low ohm readings readings,they should be about 400ohms or more. if thats good then check out spark unit..if thats good then check to see if coils wires are getting 12v. Then if that is good check resistance of primary and secondary plug wires. or just replace them anyway and that one less thing to worry about. you have new plugs and wires. it can only really be the coils or pulse generator. hope this get you in the ballpark can iget a helpful on this thanks but if i helped you fix it by checking the pulse generators i'd like a very helpful, appreciate!

The last time I saw one of these bikes, (back in 1995 or '96) I was able to improve the clutch performance quite a bit by adjusting the cable at the lever. I don't recall as to whether or not they offered a hydraulic clutch actuator, (the one I worked on was a cable) but if they did you can try bleeding it.

Sorry I don't have a manual that I can get the procedure from, try checking with your local dealer if possible, they should be able to provide the service information. If not I believe there is a Hayes manual available.

Good luck.

With the float installed turn the carb upside down so the float is pointing up adjust the tab until you see the underside of the float is parrellel to the carberator's metal flat body section. This setting will provide the proper fuel level in the carb providing the proper maintained level of fuel for performance around tight turns as well as idling.

I had the same problem with a cars clutch. Get yourself a kit and take the whole lot apart, that is the total hydraulics involved with the clutch. Clean it out and fit the new rubbers and O rings etc. You will think it is a different bike after.

hi,might be able to help,i dont want to be the bearer of bad tidings but generally the only thing that will do that is the exhaust gasses getting into the cooling system,which will then pressurize the system and blow the water out of the overflow bottle,you may find that the head gasket on your bike has failed,i would recommend getting it checked over fairly quickly because if you dont 1 of 2 things will happen,1 all of the water will get blown out when you least need it and the engine will overheat(this normally happens miles from anywhere in the dark and it is raining)or the engine will start to cough splutter and die as water in the cylinders doesnt burn nearly as well as petrol,this will also happen miles from anywhere in the dark and the rain,hope this helps...cheers ian

if its similar to my 87 600 cbr hurricane it under the small left front fairing panel.

That is a typical sound on any 1987 CBR1000f. It stems from the cam chain slaping inside the case. An adjustment can make the sound go away for a few thousand miles, however it will inevitably come back. If its realy bad (aka, doesnt go away over 1700 RPM) then you should probably adjust. Typicaly there is no problem, and just let the bike warm up and the oil pump all the way arround before wraping it up. Hopes this helps.
