Hi and welcome to JustAnswer,
Thank you for the question and your patience. Should you still need assistance for information purposes only...
Initially, two possibilities:
• air leak - check/ensure air box/cleaner is installed and seated correctly;
• over/under-voltage - test battery voltage when idling and when attempting to rev the engine.
