Wtf Is This?!?!?!?!

[Lee_250f]

ive just got my bike back and run it in. after the run in i went for a blast throught the forsetry. when i got home my mate noticed a small bit of oil on the frame just underneath the magneto cover. so off with the cover and there is a fair bit of oil in there.WTF? oil in the magneto. it was just a bit under the magneto but nonew was on the magneto. anyway i found this small hole upo the back and i dont no if it has rusted or it is just overflow for oil or sumthing???please help with wtf is this?

Hmmmm that doesn't look like a very good piece of pie. I think what I'd be doin is grabbin the WD40 and a rag and cleaning that whole area right out, it does look rather rusty, then riding again and check what's going on with it. Because at the moment I can't really tell if there's oil or just moisture in there with the rust and dirt and stuff. So clean it out then go again and recheck, if there's oil in there take it to the shop and get them to look at it. I dunno what sorta bike you got or if that hole is supposed to be there but if anything's getting in/out of that cover the gasket needs to be replaced anyway.

[Lee_250f]

its a 96 cr125. that is under the magneto and it has a plastic cover so there is no gasket. i wont have time to clean it until wednesday probably so ill chuck some pics up then.

[GStylEr]

I got an '00 CR250 and it's got a plastic magneto cover also and still has a gasket so perhaps that's part of the problem right there... But yeah let us know how ya get on when ya clean it and that.

[ALLEN]

that hole looks as if its supposed to be there,take a pic a bit further back if ya can.

[Lee_250f]

shit eh. i didnt no there was suposed to be a gasket there because there wasnt onw on my 80 either. shit eh. well here is another pic from a bit further back.

[ALLEN]

id reccomend get the cat piss out and clean that shit up spray it on that rust and then post another pic.when its clean see if you can find where the leak is coming from.

[crustydemon_69]

very messy....but id say the oil leak might be coming from the seal on the clutch actuating arm (where the clutch cable goes to)

[Lee_250f]

im gonna clea it u tomrow night. i aint got no wd40 or nething atm so would it be ok to use petrol?

[ALLEN]

use turps or kero but if you use anything like that be careful it doesnt go im that little hole unless you know what it is and its alright but i guess petrol would be fine,dunno if itl do real much though.

[Lee_250f]

well had another go at cleaning it tonight but alas not much happened. i couldnt see the hole poroperly couse the light weas in a shit spot and couldnt fing the torch. anyway heres another hoto but its not much.

[Robbo66]

The oil isnt supposed to be there. does it smell like dirty gear box oil, or pre-mix oil?

eitherway, a type of seal in your motor is blown.

start you bike up, warm it up, then let it idle. then put your finger over the black hose that comes off the motor casing, and down through the suspension linkages and stuff.

if you can feel it sucking or blowing air through there, then your crank seals are buggered!

[Yammi_man]

cool tip... lol, but i wont try it just incase it is ***ed, i cant afford shit at the moment... haha

[Lee_250f]

hmmmmmm. DAMN ****ING BIKE. always shit goin on it. i dont think the seals r gone couse it was just serviced two days ago and they said it was fine. i think ill be dropping back into the shop and gettin it checked over again. im goin riding this weekend so ill check it all out after that again.

[redbull_fmx]

You could alway try putting High temp silicone over it to cover the hole.

[ALLEN]

^^^^^^^i wouldnt do that.

[redbull_fmx]

Thats only until he gets the bike fixed

[ALLEN]

it might somehow get down in there and then it might **** shit up.id just leave it cos it looks like its meant to be there.

[[TOPGEAR]]

thats pretty rusted and shit, u better clean it all up. get a gasket for it aswell

[redbull_fmx]

Dude No offence but you bike looks like its almost ****ed.

[Lee_250f]

yes i no its shitheap bike but it goes ****ing hard thats y i like it. tsurprisingly thats the only rust on my entire bike that little bit on the magneto. anyway im taking it in to the shop next week to be serviced again and fixed up then its gettin sold and am upgrading year models.

[StUmPnthqldD23]

My old 99 cr125 was the same. i believe the exact same bottom end gear box etc as the 96. the hole is a drain from a chamber in below the gear box, it has no oil or anything else in this chamber at all. When you wash the bike that area gets a little moisture and condensation type thing and if not oiled and aired out, it goes like in your photo. i used to drop the cover off after a wash and clean it up a bit and spray some RP7 type thing. Permanent fix is buy the factory style alloy cover as on later models 01 02 onwards i think. hope this answers your questions, let me know if it's still a little confusing.

[Lee_250f]

yeh the pics i posted up are after i have cleaned it out. a fair bit of oil drps out onto the frame when i ride so im starting to worry my box is gonna seize ill get more pics when i get home from school.

[Lee_250f]

ok i think ive found out wtf it is. a mate who works at a bike shop said it is a hole that leaks as mine does when the crank seal r screwed (think its the crank seals) so u no that they need replacing. hope it doesnt cost much. has anybody replace them before?how much?

[stavross]

dude, no offence but that bike is trouble.. there should be no rust in that hole(tecnical term).... that your bottom end more aless, and that shit is a real pain.. i would sell it asap even if it goes to the wreakers.... sorry to say that, but it will save you alot of headaces.

[Lee_250f]

nah man. the bikes alright now its jsut a seal. and there isnt rust in the hole or around it for that matter. there is only a little bit on the flywheel or magneto, i dunno which one or wateva. and thats onlyu a tiny surface rust to. the shit around the hole that looks like rust aint its just dirt and oil and crap lmfao. yeh i et ur point but the bottom end is fine its jsut one seal and that hole is supposed to be there. but i am selling it very soon. lmfao.

[[TOPGEAR]]

crankseals cost jackshit. mine cost $80 supplied and fitted. including oil too

[Lee_250f]

yeh sweet. $80 is alright.
