I have a 2013 HYOSUNG GT650R that sometimes has a slow start-up. Is there an upgraded rectifier on the market for this bike, assuming that other riders may have had this problem? Other than the slow start-up the bike is fine, any ideas? I live in the USA if anything is available can have the information

Have you had the chance to get it running and idling? If yes….
- Then grab your meter , switch to 20V DC
- Go to the battery and see what the idle voltage is at the battery
- Then rev up to 5k revs max and see what the voltage is at the battery
Ie.
Idle 14.1V // 5K revs 14.6VThen also check your charging to system while it’s running to see the output of the stator (Under 100V AC not DC) , in all 3 yellow lines.
Sometimes….
- It can just be the case the starter motor is starting to wane
- Flywheel Sprocket (Sprocket that is behind the crank rotor drum) may have lost a tooth or 2, hence slower starting/slower cranking (Have a visual look after you drain oil 1st) – I hope it is OK!
- Starter Motor Relay = Yup , very common, sometimes it’s this thing that’s slowing down the start up process.
- Because you have an EFi, your battery may be too low or too weak (meaning it’s loosing charge too easily if a starter motor is cranking while fuel pump primes and all other EFi electronics start to tax the battery to start
- I would get a fresh battery and make sure it is a YUASA YTX 14BS , I recommend the battery whenever i deal with customers here in UK. batteries like Powerline are just pure junk. VARTA (German) , UNIBATT are also my favs if i can’t get YUASAs.
I hope this info helps but keep us posted and I will digress further if need be 🙂
