Good eveing fine ladies and gentlemen,

Done a wee search and found lots on the not so hassle free exup valve hoever i could quite find the answer i was looking for!

I have just bought a well serviced fazer 1000 gen one on 37k, runs beautfully pulls as she should. On the 300 mile run home at the one and only fuel stop (impressed) she flicked up the 7k exup error inditcation. Knowing the bike had stood for a month or two, when I got home I decided to service the valve and see where the fault lay. I was blessed with all the bolts comeing away freely they had clearing be serviced regulary in the past. Valve was slightly sticky and cables where slack as you know what. Greased it all up and bunged it back together going by the tutroial I found on here.

Now, ever since she has a rattle at around 2-5k fromt he exup as soon as i power on it goes.

I have read a few probably causes....

1. Cables to slack?
2. Worn bush / bushes?

I will check cables again tomorrow as its only really started since i stripped it...

My main question is, if as i suspect the bushes are worn... regardless of cost, should I buy OEM bushes or shall I get two made up by a local engineering shop?

I'm not trying to save a few quid, I was worried if I shell out for oem bushes, do the VALVE'S themself wear? Could OEM bushses still be slack?

Has any got any expeirience?

Or

The thickness of the valves as new perhaps?

From my 2007 fz6 excellent condition sounds amazing comes with complete fitting kit all you need is two rubber grommets from your standard end can! Comes with baffle! Fits bike with no modifications or mapping needed. Once more, it fits standard exhaust cowl so it's not visible!! Very expensive new grab a bargain! 

Update
Dug out a de cat to, will come with exhaust although I have never fitted it so can't garrentee fitment or running.
