Hi guys, I just bought my fzr250 a couple weeks ago. after forking over money for new tyres and rego i am now riding. <!-- s --><img src="{SMILIES_PATH}/icon_biggrin.gif" alt="" title="Very Happy" /><!-- s --> anyways, i noticed the bike i idling at very high revs. I though it might just need a tune up so i took it to the local workshop. the mechanic took a look at it and stuck his hand under the left fairing and turned some knob. the revs of the bike went lower but it wouldnt idle. it just died. anyways he recommeded a compression test to see if the engines got compression and if all is fine, he is gonna service the carbies. Anyone know what can cause this? ive already spent mega bucks fixing up other things on it. Also, my headlights just went out and i have no idea how to change it. any help anyone? Thanks Kev
The fzr should idle around 2000 revs. Most other bikes will rev lower, but then again most others don't have a 18000 red line. The knob he would have turned can either be located on the left hand side, just behind the fairing (you should be able to see this one) OR it will be in the middle of the engine just below the carbs, and just behind where the sparkplugs are) which you can reach if you put your hand in (if you take a torch you should be able to see it before you put your hand in - it will be a small metal 'cog' looking thing). I had a mechanic adjust the idling speed when I first bought it, but he turned it to about 1000 revs, but as you said it just dies. Fzr's have low compression at the best of times (most 250's tend to apparently) so getting revs slightly too low can cause a big impact. The most likely problem, if it isn't just set to low, is that the bike needs a carbie tune. As for lights - do you have a twin or single headlight model? If it is a twin you can reach behind your instrument panel and remove the covers for the lights - they just clip on. Then remove the cables (again these clip on) and then you can remove the headlights quite easily. But if it is a twin headlight I would have expected only one light to fail - which makes me think it could also be a fuse (under the seat on the 2kr).
mine is a 3ln. its a single headlight. when i first started it i noticed the lo beams were gone when i started the bike so i decided to ride with hi-beams then they died a bit later. also ur previous post confuses me. u stated 2 different solutions if i had the twin headlights or the twin headlights. thanks for trying tho. much appreciated
by the way, sometimes my bike idles at 6000rpm. and it seems to be running quite hot when it does this. do you guys think i should just service the carbies and not worry about a compression test????? cos this bloke wants to charge me by the hour for the comp.test
A compression test doesn't take long at all? I wouldn't say it takes any longer than like 20 minutes? and thats being generous. I think ud prob wanna do both though. Up to u
What I meant was that if you did have a dual headlight, then only one should have blown (i.e. it would not make sense if both blew at the same time - very unlikely coincidence). I didn't mean to refer to the single headlight as I don't know how to change them. I would say idling at 6000 is quite high, and it would get hot. Without any air passing over the radiator the engine would get quite hot quite quickly (even with the fan on there is only a limited amount of air passing through). Don't know about skipping compression test or not (as grendal said they shouldn't take long). My advice would be to get a second opinion from another mechanic. One of the other Sydney siders may have a good mechanic that they use. I have a reliable one here, but doubt that would be of much use...
well this mechaninc tells me its at least an hours work just to get to it for the compression test. anyways i've given them the flick. i took it to a mate of mine whos fixing it as i speak. could have been an air leak cos the airbox pulled off so easily this arvo. anyways, hes changing the carbies for me for free. god love him!!!!! hey, anyone know where the fuse box on my bike is? its a 3ln 1992 single headlight model. also, does anyone know how to change the headlight bulbs, i cant seem to get to it without pulling the whole front of the bike apart!!!!!!
i successfully changed my headlight bulb. for others out there with the same bike, you've got to remove the nose cone to get to it.
They really did not make the fzr250 'routine maintenance friendly'... removing the nose cone to replace headlight, remove exhaust system to change oil filter...
What were they thinkin eh Boz? Maybe hoping we all dont wanan bother and send it to the mechanics to get repaired.. wats that word they call that **** for?
