hey you guys ive got a 91 cbr 600 and i have a slight tick noise that i get when i start my bike up sounds like a valve tick but then it will stop when its warm if not it gets a lot more quite. it cant be from the oil cause i check it on the daily and i use ams oil.(should i use different oil) or do i just need to do a basic service on the bike cause its a 91?

if there is any one out there that knows the f2 like the back of their hand hit me up im trying to know all i can

 

if the tolerances have not been checked over the 20 year lifespan its probally time. it sounds like valve timing but who knows what a mechanic can come up with

 

it it a singular ticking, or sound more like a tin can full of nails being shaken?

The latter option would point towards the ole' CCT issue. would be good if you could take a quick cell phone video recording so we might be able to hear it and help you diagnose.

Drop down to the F2 section - and welcome to CBRF!
