Also,
- What size Pilot Jets are on the bike?
- What size Main Jets is it using?
- Is the airbox intact ? (put the airbox on the carb first…… then drop the airbox and carb together in to the intake pipes very carefully as those rubber necks are very difficult to get nowdays.
- Standard air filter used ?
Consider O-Rings below?

If you can’t wait for them, try to ask a local hyosung dealer ? = Don’t buy any parts from Hyosung pages that are “Blue/White” as they have a lot of bad reputation, we don’t promote them here either. Too many people got scammed online.
