Hey,  15 ft lbs  with a bit of loctite-medium-threadlock so they don’t undo themselves under heavy vibrations.  You can type in google to convert ft-lbs to kg or NM if your tool doesn’t read foot-pounds.

Could have dealers sales brochure inside or some kind of digitized format of books to read who knows lol.

It’s a USB flash drive.  Either the dealer/garage or last keeper forgot to take their item back lol.

Picresize.com is a good site to scale down images , try limiting to 1mb each on that site and save them again (that’s plenty on the forum).   I keep forgetting to change the size limit on the servers, i’ll get on it.

As for your question, no idea how to respond. Need specifics to what you’re asking.

No such thing on a standard Carby 125R it uses a regular key & barrel.
Must be for something else but we don’t know without visuals lol.

Unless you have the “numbers” of clearances per valve, you won’t know if that’s causing heat issues on the bike or premature cam wear. 15,000 is a lot of rides, so i’ll leave it there.   I usually do them at every 4-5,000 miles.

Yes the manual is correct not to tamper with the mixture screws, as then you’re in the abyss. I know what they are b…[Read more]

On the needle , put it on the “lowest setting”  (which is closest to the pointy tip) , that will lift the needle 1 more step out of the carb , then you have some fuel much sooner around 4-7k , its good stuff.   {{No extra washers etc, don’t know why other places say this but never mind lol}}

As you have a K&N, maybe consider 95 and 97.5 main je…[Read more]

Go to a local bike salvage or shop, look for mikuni DF52  or  SV650 carb rear pump.

The Hyosung uses a legit mikuni rear pump from 125cc to 650cc (same unit), its single vacuum port with 2 gold liquid ports (IN & OUT)

Running from the tank -> directly to the carb isn’t ideal.    The 250cc won’t exceed the capacity of the rear pump anyw…[Read more]

Fair play to your comments,   though i can say that if you have the books at hand and stick to its maintenance schedules and that , the bike will keep going.    Things like valve clearances can be done by even suzuki garages since it uses old style “tappet under bucket” style gixxer tappets.  The valves likely off old GSX (off the top of my head)…[Read more]

Slimmer to the rear since it allows extra fuel to cool the rear motor. I shall confirm this next time i dig thru’ some archives , but generally the rear gets a little more fuel hence larger main jet as standard than the front.

0 miles ? It should have a warranty from the dealer and let them fix it since its a new bike,  within 250 miles the FI lamp light comes on?  that’s warrants for some attention and they should replace the parts free than you forking out already.   I’ve had the FI light come on at 1K, but then the bike was 2009 and stayed in a garage for many yea…[Read more]

Hey,

Can you reply with some pictures of what your current fuel pipe set up looks like ,  click “add media” inside the white reply box,  this will upload pictures on here.     My 03 donor has a fuel pump , and an on/off manual tank tap by the left side of the frame.  Upload some pictures so it helps understand if your pipe set up is correc…[Read more]

Did the bike develop a specific issue ?
Another shout is to check the harness near the ecu sometimes when i moved my efi gv, the fi lamp would blinking if i touched the harness meaning the ecu plug wasn’t fully in, making it seem i was getting trouble but the bike still ran fine,   ofcourse  , apart from FI read outs, there is also ways to te…[Read more]

Hey,

If we can get to the basics , let us know before we go deeper in to it?

– Battery = Size should be 14BS & new.  It’s hard to tick over with a failing battery.

– AFTER it has battery changed => Check its saying 14-15v on a meter while revving around 3,000-5000 revs.  (ANY 13.X volts WHILE revving,  => change the regulator)

– Carbs = Op…[Read more]

Hey, off the top of my head it must be “YTX7A-BS” size type from Yuasa (halfords),  no fleebay links to post as there are many fakes online, best to see it in the flesh and usually halfords or bike shop pre-charge it for you to use it right away, though always best to check at home with your charger or a long ride for the bike’s charge system to…[Read more]
