Newbie: DIY tips pls

[Hammerstrike]

Hello,

Passed CBT recently and have a Hyosung GT 125. Aware it isnt everyone's dream bike but is decent and runs well for me.

I want to learn some basic DIY stuff so that I don't have to go to a garage for everything. Some of the stuff I wanted to ask was:

A)How often do I need to service the bike? I ride 70 miles a day 3-4 times a week so 300 miles a week approx.
B) How often should I change/fill the oil. Which Oil should I use for my bike?

anything else that could be done at home with not too much fuss.

Regards

Is this a brand new bike? If so follow the manufacturer's interval's, if not and it's got over 500 miles on it then I personally wouldn't let it go over 3000 miles between oil changes - especially as it's made of Chinese cheese

Change the filter at least every other time or every time you change the oil to be on the safe side.

Clean and oil the chain weekly, check chain tension at the same time.

Clean it weekly and check tyre pressures and tyre condition at the same time.

This is the minimum I'd be looking at if you're doing over 300miles a week, especially once the winter weather hits.

EDIT: Oil is a matter of preference. Find out the manufacturer's recommended grade and use that. Some people are cheapskates and use the cheapest stuff they can find, I'm an oil snob and only use Silkolene.

Note, there is no need to necessarily purchase a huge toolset. It's nice to always have the right tool when you need it, but you don't actually need that many.

If you buy a few tools of good quality, it'll likely serve you better than an entire toolset of cheese.

Some specs here
https://www.motorbikespecs.net/index.dyn/contact.dyn?flag=2&model_id=5835950&make=Hyosung

Personally I'd fit Irridium plugs
Must haves (IMO)
Buy a digital meter they start at £2.99 but would suggest getting
something a bit better if you can afford it.
Plug spanner
Buy decent quality tools you'll actually need/use to service the bike
rather than a shit load of cheap crap.
I couid probably fit the most used tools on my bike in my pocket

Like most other jobs, swapping plugs and oil changes involves threads
but these two jobs have caught out a few newbies who have cross threaded
or stripped threads in alloy which can turn a 10 minute job into an expensive nightmare.
Not sure of your mechanical abilty but it pays to RTFM at times
or as you doing here, ask for advice prior to spannering.

Read the service manual here and do all the maintainance recomended there:

https://files.hyosungmotorsusa.com/GT125_250_Service_Manual.pdf

It says oil and filter change every 4000 km = 2500 miles. Do that.

I know somebody here say use cheap oil. Do not. Engine is expensive. 1.5L Oil is cheap even if you by quality oil. For you that means you will pay say for 2500 miles for two months ride 1.5L quality oil X £9 = £13.50 if you buy cheap rubbish oil you pay 1.5 X £6 = £9 total.

You save about £4.50 really?

Given the fact that this oil lubricates the clutch too, I'd prefer the best quality ester oil like:

Let me see. Overpriced oil from that Opie site, or 20litres from Costco for ~£40. Given that the costco oil is significantly cheaper, and (insofar as I'm aware) meets the necessary spec, I'm waiting to hear why I'm so very wrong, valko?

Awesome stuff guys. Few more questions based on ur comments. Havent cleaned and oiled my chain since i bought it(6 weeks). Luckily went to a garage who did it while tighting the chain 2 weeks ago. Do i need to buy greese for it? and just give the chain a wipe..
need to you tube how to change oils.
how often u check ur spark plugs?

Cheers

A lot of your questions could be answered by a manual. Oil change is different for each bike. How long a spark plug last can depend on what type of plug it has.

For tools wait till halfords do a sale and you can get a good set for about £100 get the proffesional life time guarantee range.
