major trouble with my bike

on way to college this morning and bike lost all power i hast to clutch it up a hill as far as i could to a stop and then push it on to the pavement,

then i tryed to start it and the starter motor was making a very very weird sound like it was stuck but i did eventually get it started,

then after 2 mins of holding the revs at 5k it dropped very quick and cut out and would start again

i pushed bike all the way home charged battery and it started but the engine is making squeaking and banging and clicky sounds and it wont stay started for more than 5 mins b4 cutting out again



i took some vids on my fone if any 1 wants to have a look ill have to send you on msn


any 1 got any ideas what this could be?

thanks
dene

Is there enough fuel in the tank?

tanks full and iv checked fuel and its all clean

I would assume the stater motor noise is not related to the running probs.

Did you just hear a clicking noise when trying to start it again, if so charge up you battery.

So many reasons why the bike suddenly loses power like that.

Obviously you have checked the fuel tank level and you have fuel, next check that the fuel is actually getting to the carb, take off the fuel line and check that the fuel tap on the tank is not blocked or partial blocked, if fuel pisses out then its not.

Also check that the fuel tank breather is not clogged with crap. If it is then this will stave the bike of fuel as the tank can not replace the empty space with air as the fuel goes down, therefore stopping fuel from flowing.
A easy test is try to start the bike etc with the fuel cap open.
Not sure on the XTc where the breather is, its either a pipe under the tank or a hole in the actual petrol cap.

Also if it is blocked a clear sign is if you open the cap after the bike has conked out you should here a quick hissing noise as the air rushes in.

Also whip out the plug and have a look at it, see if you have a spark. A weak spark maybe your prob.

Give them a try first

battery fuklly charged now it starts first time but the banging sound is louder than the engine noise very worrying

[faith183uk]

Has anyone changed the plug recently?

I had someone change a plug on my old rs 250 a few years back, put the wrong one in, and due to the plug being slightly longer than the correct one, the piston kept hitting it making a very loud banging noise?

[faith183uk]

If not, if its knocking is loud and rapid, especially when at idle, you could be looking at a partial seizure ending in your rings being shot.

Piston pin, piston or small end bearing wear or seizure.
Whats the mileage?

If you were reving the tits off it trying to get up the hill, you could possible have bent the con rod?

It also depending on where the noise is coming from, could be top end as above of bottom end like big end bearing wear. Could be this if the noise is rapidly getting worse.

its done 12 thousand killometres last service waz at 10k and iv had them all by the book


its loud wen idle and it gets wrose as u rev


wasnt reving the tits off it waz doing about 5k at 25mph coz of heavy traffic

[Biker_Dene]

ok found out what the problem is

i had a service at 10k kilometres and the bike is now at 12k kilometres


id been running the bike with no oil so it fucked it up


thing is i didnt think it would be empty on oil already after only 2000kils after a £100 service 2000k ago

or would it? i have no idea?


so warranty is now void and i have to pay for all the work my self


no idea wats wrong with it at the moment tho they are checking it out for me

well he should have coz it cost me £100 and it was done by a propper bike shop in manchester

You shouldnt be using any oil full stop on a 4 stroke. THe oil should be changed at a service purely to change the dirty used oil for clean stuff to make sure lubrication is at its best.

It sounds like to me that the dealer drained the oil for the oil change and never re filled it. Unless the drain plug was loose and it has drained out, which ofcourse you would notice all over the inside bottom of your fairing!!!

I would get straight on the phone to the dealer who serviced it - god knows how you will prove it was their balls up though?

Mentioning trading standards always seems to hit a positive response in my past experiences.

Also if the dealer was a authorised Sachs dealer -which is where you should be taking your bike to comply with your warranty. Then your warranty should not be void - its either a manufacturers defect that has caused your bike to break down and lose the oil causing major damage, or the authorised dealer has buggered it up. either way they cannot void the warranty as you have done everything possible to adhere to there regulations.

Hi

4 strokes do burn oil, the amount varies. Small 4 stroke will have a tiny sump so a couple of thousand km is enough to use up the oil if you are unlucky.

All the best

My mistake, as kickstart pointed out you will burn oil, but i still think its pretty unlikely to burn your whole sump in 1400 miles or so (2000kms)

Have you always had the bike serviced at the correct time and via the correct channels? If so, i would get on the phone or write to Sachs head office and plead for a good will percentage towards the rebuild costs. I ran an Aprilia RS250 dry of 2 stroke oil at 1800 miles and completely knackered the top end of it. I blamed the oil pump, which was fine, Moto uk (Aprilia) gave me a 60% goodwill payment due to the 2 services i had undergone in keeping with the warranty. Its definately worth asking they can only say NO

Has the dealer given you an estimate on the damage caused and a price to repair yet.

[Biker_Dene]

had a bout 5/6 services opn time with the same shop wich is the main sach dealer in manchester

i doubt i will get a discount tho
