Looks like he's wearing plimmys !!! WTF :(

I feel your pain mate, having been born and dragged up on the Isle of Wight i took the plunge and moved to Wales late last year, a bikers Dream and there will be always a welcome in the Valley for you Bud. ;)

Fookin tax haven, no wonder you can afford all those oil changes, plus not much going on might as well change the oil............ only joking Chapps. :rollin

7
If you can afford it fella you can never change the lube and filters often enough. Well done, a bit OCD for me though. ;)

Right now we have got the exhaust rings off how do we tackle the header assembly which has grown in with crud and corrosion ? :'(

I always thought Copper grease true application was for high temp threaded items like manifold studs etc, not for moving parts in high temps surely Yamaha could have fitted Graphite impregnated type bearings within the collector box. Still a shit conception though. (Exup that is.) :evil

Same as i do but minus the Akra system just an open can, so thats two of us running without Exup any more ? :eek

"I might be wrong here, but I think that there's two issues. First, you've got the valve not opening properly,  but also, the ignition map is altered if it's stuck."

Big up AJ, but is the ignition map controlled by the exup servo assy and if so and left functioning without the cables would the map perform as standard ?

Yes I think you are being stupid here , so I will no longer support saving  the "Whale" .

Hmmm , I wonder if he will return to you in a months time for the Quick 8 minute exup valve service now that its functioning OK ? Sounds to me as there is probably a lot of Gen 1s out there bogging around out there with seized or semi seized valves ........ and if thats the case all the moving parts are well worn by now and all the Copper grease in the world aint going to replace that worn metal. Bin the Bitch. :lol

with a perfect engine we would have fully variable intake trumpet length, cylinder compression, intake valve timing, exhaust valve timing and exhaust length.   An engine is a mechanical pump really and as we can't adjust many of those attributes the engineers have to optimise for a specific operating characteristic.   

What we can do is alter some of those parameters though ,  like honda with opening a second set of intake vales (vtech) , benelli with the intake trumpet change (lifts the 'cone' of the top) and putting valves in the exhaust to alter the back pressure.

I do look forward to the day when we have pneumatic valves, forced induction (turbos will return!) and variable exhaust capability to give us a motor able to operate at it's most efficient capability over a wide rev range.

Right now bikes are built as leisure devices and the requirements for fuel economy are secondary to power and basic marketing requirements.  In 20 years i think we'll be riding smaller (400cc?) engines yet generating more power and we'll go fully automatic,  we'll have a gear shifter and clutch - just they won't physically do anything as the computer will control the gear control as i think we might have more gears to allow the engine to remain in a specific rev range for efficiency requirements.

Brilliant I'll be in my 90's then much lighter bikes less physical movement to be able ride but to still able to bend the hands on the rev counter/ speedo, magic. Hopefully exup will be long gone by then so that i dont have bend over to remove it.......... :)

my exup valve had been broken for a few years.   One of the bolts for the cover had snapped and i couldn't drill it out.   So with two bolts holding on the cover / housing it didn't go on flush so pinched the valve off centre and jammed it. 


Anyway,  end result was the valve wouldn't rotate so i just removed it.   I took the exhaust off to paint the engine and tidy up the bike as i've done 30,000 miles now.  With the bolt removed and a helicoil fitted at a local engineering shop i could refit the valve.


The result - OMFG  :eek [size=78%]- [/size]i could not believe the effect, it was like a new engine was fitted.   I thought there would be a minor improvement and had forgotten what the bike was like with the exup working.   


I'd always keep a *working* valve - also i've been Ivanised (by the Mike incidentally)


[ although i will be posting a question about valve operation as it doesn't seem to be resetting to the fully closed position - but the performance is night and day ]

Was it possible that you had been experiencing the bikes performance with the exup in a seized closed position and after attending to it has remained in seized in an open position......... ?  :D

17
You certainly know what you're talking about with that last comment. :)

From you my friend I take that as a compliment. ;)

18
8 minutes is all it takes to bin this heap of mechnical crap, then Ivanise the carbs and modify the air intake. Afterall isnt that what Amal carbs (different size jets and throttle valves ) and the likes of K&N filters with their replacement air filters allowing standard engines to be uprated to a higher performance?

As previously stated " same old faces "   there is none so blind as those who will not see.

19
Same old faces.......... ;)   Exup belongs with the industrial revolution. :z

Atta boy Falc, that Kernow air must have a mellowing effect ! ;) Just going to boot the old Non exup Gen1 up the valley and let her breath and fart naturally.......... :D " Bluethou whip it out."

So everyone riding Gen 1 Fazers have entered the WSB now... no seriously  Falcon thanks for the technical info and your opinions on the pro's of exup. But I'm well into my 6th decade now and maybe, maybe my perceptions and reactions are not as fine tuned as they used to be which could be why i felt no benefit in keeping a well worn exup set up or having it removed.

 :D

22
Are you showing it off at the Bike Shed meeting this Sunday then?  ;)

Hardly good enough for that Steve, besides i would probably get Lynched by the Pro Exup mob..........for removing my system.  :eek

Most who have removed or disabled the EXUP do notice a detrimental effect on low-mid range performance, irrespective of any jetting changes.  You're fortunate in that you aren't able to discern any loss. :)


No, the bike has'nt experienced any loss, i as  the rider am able voice that experience and still maintain that re jetting the carbs and providing the correct air intake counteracts that over expensive mechanical abortion slung in our exhaust system.   :D

I'm a bit old skool as far as exhaust systems go, only ever used to tuning British 4 stroke twins and rule of thumb was always providing the top end had the right ammount of fuel and air get rid of it via the exhaust as quick as possible ( it was said 11 inches of pipe from the exhaust port was the optimum length ). So why on earth have this chunk of casting blocking your escaping gas ? My Gen 1 1000 has been Ivanised and such was the state of my exup system apart from the servo and the outer cables, the rest completly unserviceable that i have removed it. Contary to many comments made and possibly about to be made it has made no difference in my opinion, the engine performs outstandingly.

Stand back.. :)

Hah hah........ :D
