I have recently perchused a yamaha fzr250rr, and i have changed the oil and oil filter, using penrite fully synthetic 20w60w and it seems i am loosing alot of oil... I approximate that im loosing 1litre every 500km's, and i took the fairings off and drove it to the mechanic to ask for an opinion and he thinks that the engines using it because there doesnt appear to be oil everywhere so its not an oil leak... I first thought it was a leak though because my bike isnt blowing alot of smoke any coments/advice?? maybee a different type of oil i could use or an additive or something to stop it from burning the oil? does anyone know whats wrong with it?? thanx for any help/advice anyone may offer -steve
Sounds like an interesting problem... I have no ideas regarding what it could be. Hopefully tim's suggestions help!
the end can?? are you talking about the oil filter because the oil filter is a paper one not one of those screw in ones if thats what you mean?? sorry if you mean somehting else its my first bike and i dont know that much you will have to be specific
The end can is the muffer on the end of your exhaust pipe. You might want to check the plugs and see what colour they are. If they're black/sooty, then your prolly burning oil. The mechanic may not have checked them due to the time/effort in getting them in/out. Worth a look, good luck. <!-- s --><img src="{SMILIES_PATH}/icon_smile.gif" alt="" title="Smile" /><!-- s -->
ahh ok... umm yer thats what he was showing me all the black stuff at the end of the exhaust he said it was carbon dioxide mixing with air or something i forgett exactly but after seeing that he said 'its definetaly using oil' is there anything that i can do to make it use less oil?? fix it up a bit maybee?
Did you buy private or dealer? Is it under warranty? Gee, I hope someone on here can help you, I don't mean to sound alarming. <!-- s:-? --><img src="{SMILIES_PATH}/icon_Eyecrazy.gif" alt=":-?" title="Eye Crazy" /><!-- s:-? -->
did you put the sump plug back in? <!-- s:lol: --><img src="{SMILIES_PATH}/icon_lol.gif" alt=":lol:" title="Laughing" /><!-- s:lol: -->
- Check that there is no oil being dropped; stick a newspaper under the bike overnight after you've ridden it. - Check the plugs; if their gummy, sticky, and black you've got some internal engine work that needs doing. Major expense, major bummer. - Check the seals on the engine; just inspect them once you've got the fairings off. Any obvious oil coming from any of the seals? Out of interest, i know you said you bought it recently.. but it may take a bit of riding before the oil residue on the outside of the engine will come back. It's a favourite trick of private sellers (and dealers) to just go to work with a full bottle of engine degreaser before selling. Sad, but true.
its definately not dropping oil... theres oil around the engine which the mechanic said was normal because engines just sweat oil bought it from a private sale not really keen to spend big money to rebuild and stuff if it is kaktus i might just sell it and let someone else fix it up and buy a 2stroke bike like an rgv... i havnt checked the plugs i dont see much point in checking the plugs because if its not leaking and its using oil it must be burning it but is there a better oil i can try that wont burn as much or anything like that im pretty convinced now after speaking to some poeple that its burning the oil
The bike is also abit out of tune and possibly has fouled plugs because when you stick it it hesitates alot if i got it tuned and got new plugs would it do anything good for the bike? i was riding it home tonight and it was the first time i really gave it over 100k/h and after about 130 it just wouldnt go on about 16,000 revs trying to stick it and it was just hesitating i went up a gear because i thought maybee the revs were too high but still wouldnt go anywhere was a slight up hill but not major ??
You should be able to accelerate (all be it slowly) up a medium incline at about 100km/h in 5th. If it's having a hard time doing this you might seriously consider laying down the cash to get the plugs replaced & having the carbies looked at (ie. retuned, possibly even re-jetted).
Yep, i agree. Don't give up on the bike till you've had a crack at the "minor" things (you've done the oil, so just spark plugs, valve clearances, fuel and air filter, fuel pump, carbies, battery). I had similar troubles early on but all this stuff just needed sorting. Was well worth it. Good luck!
if i replace all of those things... plugs, fair/fuel filter will it stop using oil?? also i cant find the thing to turn up the idle on my bike i have a 3ln1 i think the 1 with 2 headlights and twin disk brakes at the front... my friend has an fzr with 1 headlight at the front i think its a 3ln3 and his idle adjustement i believe from what he has told me is on the right hand side near where you put the oil in theres a little thing you can turn around... he couldnt find it on mine? Also how do i check valve clearances? Sorry if my questions are dumb its my first bike and i like to do things myself so i can learn...
idle - on the 3ln's the idle adjustment is relatively easy to find (as you know). On 2kr's the idle adjustment is in the centre of the engine, behind the engine block / below the fuel pump. If you get a torch/flashlight you will be able to shine it in there and see the dial. You do not need to remove fairings - you can get in there without. It won't be very comfortable for your hand though as it puts it in a very awkward posture. I don't know how to check valve clearances - from what I understand this is a pretty major undertaking! changing plugs etc> it may reduce oil consumption. However, I would be guessing the main benefit from doing this is to check out the other parts of the bike to see if they could provide any indication of why the oil is being lost. Spark plugs, air filter, etc. are all easy but can be very telling at times. For loosing oil there are only 2 possibilities (in my view): you are burning it (in which case you would see smoke) or it is coming from the engine and you are dropping oil (in which case you would see a small pool below the bike). As a question for anyone - is it possible to only loose oil while actually riding the bike? If so, then this could explain why oil is not being found when left sitting... A possible check, I guess, would be to turn the bike on, and while in neutral rev it to 6000/8000 for about 5 minutes and see if anything happens.
If you are loosing oil it'll be either from either the top or the bottom of the engine. If it's from the bottom, then you'll see oil on it, if it's from the top, generally it'll smoke as the oil is burnt. warm the bike up, get a mate to follow you as you ride the bike. Rev it right up and get him to watch for smoke. Don't be scared about reving these things, I've lost count on how many times i've hit the rev limiter on mine. <!-- s --><img src="{SMILIES_PATH}/icon_smile.gif" alt="" title="Smile" /><!-- s --> If you really are not sure, then spend some $$ and get a mechanic to check it over competely - then you'll know where you stand. It's worth the money for the piece of mind. I had some sooty smoke (not oil) come from mine when I went above about ~15,000, but after giving it an absolute hiding on the track it cleaned up. My ZX9R runs rough after a week of commuting, opening it up once a week gets the cobwebs out and it runs smooth again. <!-- s --><img src="{SMILIES_PATH}/icon_cool.gif" alt="" title="Cool" /><!-- s --> These engines are designed to run hard.
i have already done that, and thats why im saying it doesnt blow alot of smoke... my mate said it was blowing a little bit but not much... the mechanic said the engine was using the oil though because of the inside of the exhast at the end the black stuff
from my understanding oil should not be able to get into the exhaust unless there is a broken or worn seal somewhere. Exhaust is effectively a seperate system. So unless you are blowing blue smoke then I can't see how you would be able to tell oil is being used on the basis of the carboned exhaust . I may be missing something obvious though...
The way for oil to get into the exhaust like that is by worn valve seals. The oil pump pumps the oil to the top of the engine and gravity takes it back to the bottom. If the oil passages are restricted, then the oil will pool in the head and leak past worn valve guide seals. It is then blown out with the rest of the spent gases into the exhaust system. It will not necessarily be burnt oil as in smoke. From my understanding, smokey engines are in need of a ring job.
