Question about 2005 Honda CRF 450 R
I just got a crf 450r and every time i go to start the bike it always back fires for ages then it mite go or not is it stale gas or is av gas the bike shop ffilled it up when i got it what would be a good gas to run plz
Hi and welcome to FixYa,
Initially, backfiring is a spark/timing issue or contaminated fuel (water) or as you stated stale fuel. AVGas would not result to backfiring but rather a stronger pull though would heat up easily.
Good luck and Thank you for using FixYa. Happy Holidays.
