hi had my streetfighter now 1 year goes for its 15000 valve check next week went out for a blast today The bike seems to have got louder from the standard cans and can here the air filter more? ( put a new air filter in a couple of days ago because I thought the old filter was no good ) but coming home the bike is well loud need earplugs ? Don’t know if it’s the exhaust valve ( had problems on a blade years ago and that was the valve ) Any suggestions Cheers Gaz Ps Bike is a 14 plate 848 streetfighter
