[quote author=Silverlegacy link=topic=16061.msg186007#msg186007 date=1425638719]carb rubbers not leaking, although not cleaning carbs yet as might be a bit beyond me to be honest.

I am talking about the diaphragms inside the carbs, not the inlet rubbers.

well not had carbs apart so cant check this, might have a look in the haynes manual see how big a job it is, im sure its not going to hurt to at least look and clean that carbs, as could obviously tick a few things off the list in one go.

diaphragms are easy to check.


take seat off
take tank off
undo the 2 10mm bolts on the mount for fuel pump and coils.
move it out of the way


2x phillips screws on each carb top.


take the black cap off watch for the spring and loosing screws.


pull out the black rubber bit inside and hold it up to the light to inspect for holes.


push the needle out and check which setting the E clip is on.
push needle back in
put back into carb
cap back on the correct way, it has a little bit sticking out that should match the carb top


move on to next and make sure the E clip is in the same place whilst checking diaphragm.

Cheers for that Paulfzs.


Pretty sure i can follow those easy instructions :-)


I dont mind tinkering a bit to see if i can resolve it, just doubt i can do anything too major.


But appreciate the help a lot :-)

Did this happen suddenly of was it a gradual thing?

pretty much since i had the bike? which was around July time last year.
I put up with it for a while but then started looking on here for a cure for it.
I tried to iron out the little niggly things like the headlight buzz and had it serviced and new chain and stuff on there.
I can live with it as i only use it to daily commute to work and roads are pretty slow where i live and only 7 mile commute through town (30) roads and a bit of a 50 main road, so if i just keep the revs down and change up early its ok, but i should be able to ride the bike like its supposed to and use the extra power if i need to with out it feeling like somethings wrong with the bike.
Like i said before i am probably doing a terrible job of describing the noise/buzzing and obviously makes it hard for people to help me diagnose the fault.
When it was dyno'd all the guy said was its running lean at 6-7k and could do with being jetted, but as there a dyno jet dealer i guess this might just be a ploy to make money and several people on here have commented saying that its not done there bike much good.
I keep going through different posts on here and a few point towards different things, so trying to check as much as i can but trying to take every ones advice on board and see if i can get it sorted.
