Okay, this is a topic in which i was getting help on earlier in the totally wrong forum [sorry guys! <3 ]

Having trawled the internet like a possessed woman on speed, I've decided to go with my mechanic's wife's bike which is for sale! [YAY!] its a Suzuki GN125, it last had an oil change about 4 months ago, they've used a cheap oil out of Halfords and I'd like to put a better quality oil in...

However... I've never done a thing on a bike, [ignoring being seven and taking apart my dad's bike because I don't remember doing it but he remembers it] so I'd like someone to walk me through how its done and what I should be looking at to keep the bike maintained. Its going to be my pride and joy for the next two years and I want her purring like a kitten so to speak.

Help would be greatly appreciated. <3

Where does one start? Smile

You will need a manual. Haynes do them but they're expensive.
There are manual for lots of bike on line but you some time have to go to bad sites to get them (or maybe not and just get a disease).
Perhaps some of the others on here have links to safe sites.

You need a set of combination spanners, a 3/8 socket set, Long nose pliers, engineer's pliers (The ones with shorter flat chunky jaws)
Not sure if that engine has a spin on oil filter or not. If spin on you will need a filter strap or a pair of filter pliers.
That's about £60/£70 of tools for a 'starter' kit.
As you go you may want to add to it. (You will add to it as tools are like drugs.)

I like to use good oil it's not much more £ for some peace of mind.
Some folk shop at Aldis/Lidl/Iceland I can afford ASDA/Morrisons/Tesco (sometimes Sainsburys if flush).

sorry to be a pain in the behind but spin on oil filter? I have so much learn... looks like I'm going to be googling all night! <3 hehe

I'm really sorry but I'm a complete newbie who is more than eager to get her hands dirty and covered in motor oil *grins*

My tool box at the moment contains.... *peers at box* long nose pliers, stanley blade, computer/laptop screw bits [including torx and tri-wing], hammer [coz every girl loves a bit of demo work ;p] and mains hammer drill [see ref to hammer]

^.^ looks like i'm getting some more tools then! *excited squeal* Off to B&Q in the morn' then xD

The are two bolts under the engine.

One is the drain plug I believe is 17mm the other is 14 and not to be removed.

Worm the engine up put it on the centre stand and drain oil
into container.leave for a while to drain.
Put drain plug back in not over tightening it.
Put oil in checking the inspaction glass window in the clutch cover until
half way up window.
1.5l iol I think but it says below the filler cap.

Change oil filter every second oil change and this one as you
can't be sure when it was last changed.

There is a cover to the front of the clutch casing with 3 10mm
nuts.
That is where the oil filter is.

@Paddy Blake: umm.... is there something wrong with the information he gave me?

EDIT: The bike doesn't have a center stand, will that make a difference?

The GN 125 should have a centre stand and you check the
oil level while up on it.
This means that if you check the oil level off centre stand it
will look to be too much as the bike is not tilted forward as
it would be on the centre stand.
Check what it says on the right engine casing how much oil it takes
and all good as the oil filter change does not make that much
difference to the oil needed.

Are you sure it's a GN 125 and not some other Suzuki *N 125. ?

I never seen a GN 125 without a centre stand but some other 125s
don't have them.

Well.. he said its a GN125... and he's been riding for so long [20+ years] I think he has bike coolant for blood. He said he modified the bike so it'd take a side stand rather than a center stand as his wife is a short ass like me. ^.^

Just be sure the bike is upright when you check the oil.
Then all is good.

I found them to be good bike.
Had 3 GN's and more GS 125's

Thankies! <3 I'll post up in pictures when I get the bike! <3 *cracks knuckles* Then i get the fun stuff of oil changing! *squeals in delight* Is there anything else I should know about? The owner did tell me that the bike has new tyres and brakes.

Christ on a stick, the bloke could at least do the oil and filter before flogging it, ought to show you how, if he is that cleverer superer spannerman?
Take a non shiny motorbicyclist with you, before you shell out on a nail.
However. Somehow, that '4 months' smacks of honesty, but then I am a gullible fool. There is no reason why you have to be one, too.
But a GN125, any 125, will have had a hard time in 4 months.., maybe a nail. Maybe it weren't owned by an eegit!

caveat emptor. Wink

The GN should have both a side and centre stand.
I would ask him to put it back on as it's needed for when you
have to take the wheels off for tyres/back brakes/back sprocket.

It makes no difference what hight you are as the centre stand is not for
when you are sitting on the bike.
It's for use when you are off the bike.

Tbh it all seems odd to me.

Do post a picture BEFORE you buy the bike or at least be sure
it says Suzuki on the engine.

I think it could be a Chinese copy of the GN and that is why
it had no side stand.

Just off topic slightly - it's worth upgrading the front brake on these. They really are woeful. I got so used to using rear brake only I had a hard time getting used to using the front again on my lessons!

Firstly, do not set your heart on buying a bike unseen, no matter how charming a rogue is selling it.

Apply the same pre-ride tests to it that were covered on your CBT and if anything seems wrong, walk away. There are no shortage of 125s out there.

Which will already be far better quality than it was designed to use, regardless of whether it's a legit GN or a copybike.

You're right to change it straight away, but any cheap 10W 40 mineral or semi synthetic oil, bike or car, but without friction reducers will be fine.

I use whatever's cheaper in Morrisons or Lidl, which is often "CarLube" branded, and I change about twice as often as the manufacturer recommends. Fret about oil quality if you have a race bike or genuinely plan to keep the same bike for 50,000+ miles.

On that, I guarantee you that the moment you ride anything bigger than a 125 that you'll want to get licensed up ASAP.

Height is not an issue. My big tall rugged manly adventure bike has a lower seat than many 125s. Don't waste too much time on a tiddler.

Had to turn the bike away. I'm really glad i could your advice on this!

The bike was not that great. Sticky gear box that grinds horribly when trying to go into neutral, brakes weren't great, exhaust test [put hand over exhaust and the engine is still rumbling away when i'm pretty sure the engine should choke on its own fumes]

So I went to my local bike shop where my uncle works... and boom I end up buying a Lexmoto Michigan new. xD I finish paying for it by 27th Oct. Woo! XD 1 Year worth of warranty, an uncle who will get me discounts on servicing and friends willing to teach this newbie how to maintain her.

To be fair, if you know nothing about spannering, the bike has a warranty, and you're asking a family member to maintain it under said warranty, it will last until you do your test. A CBT only lasts two years after all.

My thoughts entirely. I run on frequently-changed supermarket oil and have no problems. Talking of which....

What is the cheapo supermarket oil de jour? Last bottle was the Blue-bottled ASDA 10W40 semi-synth but seems to have been discontinued.

Home bargains - £9.99 for 4.5L 10W40
Wilkinsons - £15 for 5L 10W40

I alternate between them (whichever shop is nearer when I think I need to buy oil).

Lidl sometimes do 5L for I think £12 but the one near me is always sold out.
