Reply To: First time GV650 owner seeking guidance
If the bike looks good , generally the GV650 is a solid bike.
Every owner would be wise to:
– upgrade the stator and regulator to a mosfet one (like what you saw on the shop)
– upgrade the caliper pistons to stainless versions and braided brake lines from Goodridge UK.
Use motul factory line coolannt.
Look for any burnt plugs near the regulator to see if previous owner put a knock-off aliexpress regulator on it?
Go for a little test ride again and take note of the clutch , if there isn’t any rattle or slips , then the clutch should be OK. They love Motul oils, so as per Hyosung service manual it is advised to use “premium oil” , cheap oils are not worth the engine rebuilds later even if it’s an actual distant cousin of the SV650 (Hyosung made both SV and Hyo650 engines, as they did make engine parts for Suzuki since the 80s before they split up as Hyosung did have an R&D plant in Japan. ) so quality of the bike is dependent on how well the owner looked after it .
Tyres = check for any side wall cracks , then you know if the owner was using OEM tyres or not , at that mileage you said, it likely still has very old rubber tyres on it. So expect to put fresh ones in for a peace of mind, blowouts are not fun.
You also have the comfort of downloading the manuals on this site which will help you look for every small thing during service time.
Lastly , check the forks are in good condition or if they need new seals. If you ever have to change seals, put fork gaiters in to protect them from road pittings as they use GTR forks)
