fazer 1000 exup valve noise

[dudejb46]

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?

On my Exup1000 the bushes are different to the arrangement on my 5JJ R1,in that there are two on the shaft opposite to the pulley on the Exup and one bush on the R1.In order to remove the single one on the R1 there are two very small screws that are removed so that a small punch can be used to knock out the bush in what would otherwise be a blind hole.But on the Exup1000 the two bushes are quite a loose fit.

I do get a slight 'squeek' every now and again and while on holiday in France the other year I did get the tacho indicate an Exup valve problem,but it only happened that one time and not since.

Did you remove the Exup valve itself when you had it apart?
Is it at all likely that one of the bushes has fallen off the end of the valve if it was removed from the housing?

From what others have said on the www.exup1000.co.uk forum,some high temperature greases do not last very long in that environment and others have said that where the genuine Yamaha manual says not to use any grease,then it is better to follow that advice.

From what I have seen,the cost of those bushes is quite expensive for what they are.Having got some stock of the required material then,as and when I need them,then I will make myself some.They are not complicated and so should not cost an arm and half a leg should a local machine shop be asked to make some for you

Just found this fiche and it does suggest that the bushes on the end are two piece and that there is a bolt in that side of the collector so as to access them if they are stuck
