    Hello Chelsea, welcome to the site!👋

    I’ll start of by saying I always fancied a go on a norton bike, few years ago i was involved in a shed built cafe-racer type project.  I had sold the honda anyway!  fun times.

     

    Aquila 250s are quite punchy & honest vtwins compared to the Ninja 250s (which Americans think its a fast bike haha).  Congrats on your purchase, I would also look in servicing the whole bike myself if it was stood for sometime!

     

    Fresh oil, fresh fuel, filters & the usual TLC goes many miles away.

     

    For GV250 service books in PDF.
    Have a look on this link below:

     

    https://hyoriders.club/forums/topic/download-gv125-gv250-aquila-mirage-service-manuals-hyosung-owners-books/

    Let me know if that book helps, I got many PDF files uploaded to the website. Still got more to do

    Also GT250-EFi/Ei also shares the same engine as the Aquila250 so it uses the same electrics (in most places anyway)

    Hi,

    It would be better to drain old gasoline if there is any left  🙂 .

    Hi Marcel

    Thank you for coming back to me. I enjoyed riding the Norton’s and am looking forward to riding this Aquila GV250. Just need to tax and insure it. I know the previous owner did put fresh fuel in to demonstrate it running, but I take on board all the other things you say I should do.

    I had already clicked the link you sent but that covers the owners manual, which I already have in book form. I’ll have a look at the GT250 because if its the same engine and wiring, then that will do fine. Thank you again

    Just downloaded the GT250 EFiService Marcel and that’s exactly what I need, thank you, saved a few quid lol. I’m not a mechanic by any means but can do the simple service jobs as long as I have a manual to follow. Now I have thanks to you.

      Glad to hear you had spotted the other books, if there is anything missing just give us all a shout!

      Who knows, you’ll be back on 2 wheels just before this summer break!

    Hi

    Finally getting round to using the bike for the first time, insured and taxed but taking advice and changing oil & filter first. What is the best filter to use ? There are so many on eBay. Are they specific to year and model (my GV 250 is a 2016 efi model) because most have the same number HF131.

    Also I need to charge the battery, I assume my ordinary 12v car charger will do the job. Is it OK to charge it  on the bike or should I disconnect the terminals first. I don’t want to do anything that might damage the ECU as I know that is an expensive box of tricks.

    Sorry that these are simple basic questions but I’m new to all this and your advice would be appreciated.

    Hi,

    I use this oil filter without any problem : https://www.la-becanerie.com/maxi-scooter/moteur/filtres-a-huile/filtre-a-huile-hf131-pour.html

    For charging the battery, I recommend : https://www.dafy-moto.com/chargeur-de-batteries-moto-optimate-3-tecmate.html

    It is connected permanently, exepted when i ride, of course  :-P, and my battery is always OK (13 V) and there is no problem with the ECU.

    I hope this will help you.

    I own a GV 650 FI 2007, so be careful that the oil filter I indicate will fit with your GV 250 2016.

    This one might do too, but it’s much more expensive : https://www.ebay.fr/itm/FILTREX-Filtre-a-huile-pour-Hyosung-GV-250-i-Aquila-classique-2016-/162993316392

    The Hiflow HF131 is confirmed as the correct one and I have purchased off eBay for £8.64. Thanks again Daniel.

    Daniel is correct.

    The aftermarket HIFLO HF131 is correct for all 125/250 twins.

    Normally i send the genuine DAEWOO filters that I import from Korea anyway with  O rings

    As per books its a good call to replace the o rings too.

    Best battery charger i have is the DR. BIKE BATTERY charger.

    You can get it from J&S accessories UK  locally or online.   has light bars that tell your battery’s health when charged up  (is it holding up etc..)

     

    Good luck!

      Thanks for the advice and information. Yes I did notice that the O rings are not supplied which is a bit stingy when you consider the costs involved. My bike has only covered 40 miles since new so the oil ring shouldn’t need replacing. I’m just taking your advice as its stood unused for over a year.

      When I got the bike home,  I found a rubber gasket hanging on the handlebar mirror. I’ve now found out that it belongs to the rear light assembly. Why the previous owner found it necessary to remove the light and then replace it without the gasket is a mystery. Once I have the battery charged, I’ll check if the rear and brake lights are working correctly. In any event I shall have ti take the whole assembly off to replace it properly with the gasket installed. Strange eh ?

      Funds are a bit short at the moment so I’ll give the battery a quick boost with my car charger, its only a small one and of course I’ll disconnect the poz terminal and keep my eye on it. I will certainly buy the Dr Bike charger when funds improve. Will it be OK to keep it  trickle charging with the battery connected or should I take off the poz terminal ?

      Thanks again for your help and time Marcel.

       

      Regards John

    It will discharge slower when kept in a dry place disconnected.

    Or a bike trickle charger helps too!

    Reason I didnt mention cars is due to the huge amounts of current that passes through the car electric system (too strong for a bike battery or bike loom)

    Some cars can fry up a bike harness ( they are only rated 10amps mostly) when the car is on/running.

    It is OK to disconnect the car battery.   then join it to the bike ONLY to start it.

    Once it fires.  ride 10miles, the magneto of the bike should add some battery juice by then (charging)

    I think I’ve solved the mystery of why the tail light gssket was not fitted. Ive taken the light assembly off and its been damaged. All three bolts have been broken and fixed/ glued back on with body filler. The problem is that one or more bolts are angled incorrectly and consequently the light unit can’t be pulled tight to the shape of the mudguard. Therefore the gasket won’t sit tight as there is a small gap.

    Im reluctant to tighted the nuts up excessively as the pressure may damage the bolts again.

    Although I’m not sure if it will work, I’m thinking of using a black rubber sealant to fill the gap. Any ideas as to what would be the best product to use ?

    That should work.

    If you can, take a photo of the situation.  Then access this forum via a mobile device , tablet or pc – Then click “Add Media” at the top to attach a picture in your replies.

    It’s just strange what has been done to the bike! bit of a Frankenstein situation there!

    Thanks for the reply Marcel. Yes its very strange situation, I can only think the previous owner gave the tail light quite a wack to break all three plastic lugs.

    By the way I did take a photo but when I clicked add media it come up with a completely different set of pictures that were not mine. The workaround looked a bit technical so abandoned the idea. The light unit is back on the bike now anyway and the gap at the top is only about 5mm so hopefully will fill with the sealant OK.
