Right, noticed this today, done a little reading up and it sounds like it may be the gaskets at the headers have gone? It isn't blowing from the can and iv read that if its burbling on acceleration at low(ish) revs and popping alot on decel, it could be those gaskets.
it also ticks when starting from cold which goes away after it warms up, iv heard this is ANOTHER sign of dodgy gaskets,

are there any particular bolts that have to be used to bolt the headers to the engine because its been mentioned that they just tend to f**king snap for fun?

Another thing iv read is that it could be the carb rubbers and to check those first i need to take the tank off etc and spray a little WD on the rubbers and if it stops burbling temporarily it could be that.


any advice would be much appreciated :)

well its easy to check. best remove your mids and if possible get a mate at the back to cap the end of the can with a rag for short bursts, it helps lesson any noise and this should help pin point where the ticking is coming from. if you have talc powder puff some over the top of the pipes and clamps before you start it up as this might also help pinpoint any leaks. it may go away when warm simply due to expansion.

Also look for loose clamp nuts or worse still snapped studs or even the clamps themselves, something i have seen. if tightening nuts they must be tightened level and not overtightened, not tightened right down to the base of the stud.
Changing gaskets is easy, i prefer copper rather than alloy gaskets and if you have reused them after removing your pipes then its maybe best to replace them with new now.
