Hey,
The jetting sizes for “Mains” are OK with a variation of 5 or 2.5 it is because some states in your country or even EU countries have certain emission regulations , so if the bike arrives “downjetted” with
- charcoal cannisters
- EGR (they errornously call it) (actually is called AIS or 2nd Air Valve System)
It would then make sense as to why Korea also has variations of their manuals but….”beside jetting” , 90% of the book tends to be globally correct for all their models as no other country has a “special carb” than the other country etc. The workshop manuals used to be for dealers in the old times when servicing or trying to honor warranties etc, we consumers just got the “cut down” version call owners manual which covers small owner maintenance leaving the big stuff to garages & dealers 😉 but i digress i assume you know this already
GT Naked models (250cc and 650cc) all use the same parts as the R model of the same year except ,
- R’s tend to be twin discs + nose metal cage added for face fairing
- Frame has a “2 stubs” to mount the cage (click here)
- Their own Box Headlight that is dual lamp (h1 & h3)
- A digital dashboard for 250R carbies only (Since carby GT250 has a twin old school dials)
A GT650 naked will have digital dash but usually towards the end of its carby era , transitioning to EFi (circa 2008-2010)
GT650R carby since 2005 has had a digital dash
Now if a bike has an “older twin clock” style dash , it will have a harness tied specifically to that. As some Naked models won’t accept a digital dash etc without its R harness variant (or EFi harness for EFi clocks) etc
All EFi models of GT naked use the same dash as their R sisters.
As i have learned over the years , the sections of manual covering the “facial” plastics or extra body work isn’t covered in great depth anyway, as fairings for R models are straight forward;-) , i am not sure what they would need to cover? Typically if a fairing breaks , Hyosung would say replace (or we over here in UK , send it to the bodyshop guy for repairs and repaint 😉 )
I think you will be OK with the current paper manual you have but if in doubt about a specific section , you’re welcome to ask!
