Hey all, recently acquired an 05 GT250R Hyosung and would like little by little overtime replace/upgrade/modify parts of the bike so it can be more consistent and reliable.
My question is what would you do it your Hyosung to bring it more up to scratch? Possibly a priority list? I’ve read the rectifier is a good place to start and replace, any more suggestions?
I’m not the most mechanically minded but do like the process of understanding moto-maintenance and QOL changes one can do to a bike, specifically to a Hyosung in this case.
Current plan is to replace all the relatively easy-in-scale fluids and oils like: brake/clutch/fork/engine and find a way to adjust the rear suspension and the seller stated the owner before them were smaller in size and adjusted it to be quite bouncy in comparison when I’m riding.
Also noticed the brakes are quite horrendous compared to my old bike (97 TU250X), any insight on that?
Many thanks. -
Hey & welcome!
Honestly , the sky is the limit but off my brain , this what i could say in my opinionĀ (all are important), and whatever else not mentioned is considered “upgrades” to your desires.
Valve Clearances
Piston De-carbon
Stator UnitĀ (if not in OEM spec)
Regulator (first electric object) (don’t cheap out on aliexpress trash)Tyres = OEM ones are suicide bricks in the rain
Brake Lines = Goodridge Stainless
Brake Fluid
Brake PadsĀ = EBC Sintered Metal
Headlight BulbsĀ (old ones go yellow and get less bright) = OSRAM NightBreakers are great halogensĀ (We’re not allowed HID’s in UK or LED bulbs)
HID’s too fussy of a job.Ā LED’s make me want to throw spanner at the rightĀ (too bright & glaring but does not travel far enough) Halogen wins for now. Unless Hyosung makes a headlight out of LED’s & road legal like Audi R8
Carb Overhaul = (whatever is in it , ie fresh jets , fresh slides (diaphragms) , good clean up
Manifold Intake Pipe Rubber O-Rings
Air Filter
Spark PlugsĀ = Stay stock CR8E orĀ LASERĀ ones.Ā Ā IX-Iridium are rubbish.
NGK Spark Plug caps = too important as OEM caps crack a lot & leak sparks out!
Motul 7100 or 300V oilĀ Ā (or Silkolene Pro 4 Oil)Ā = Recommended oils.
Oil Filter
To make it last longer, i change oil every 1,000 milesĀ = Bottles are cheap but a replacement engine isn’t, call me OCD lol.X-Ring chain is good,Ā stick with JT or Japanese brands = You WILL snap with chinese chains.
Sprockets = stick with JT or SunStar Japan = All other brand sprockets are just rubbish, they slowly chew up the front engine shaft!
However PRO-X , Renthal are trusted sprocket brands too.// Meditation doesn't mean you have to sit still....
