RPM clock doing weird things

[purplebear7]

Hi Guys,

I have a biking buddy in the USA .. he ends most of his posts with: 
    ''What do I know .. I just work at the Car Wash'' .. so on that basis .. here I go  :\ .

I had three Gen 1s .. and never ANY Exup Problems .. it really is an easy job to look after them .. once you've done it.

One little extra thing I used to do was 'paint' the whole Cast Iron Box (the lump that holds the valve) with a thick coat oil ..  OLIVE OIL  :eek ideally when the unit was very warm .. but not red hot. 

The Oil (of course) then burns on .. and smokes and stinks for a few minutes .. it forms a black 'coating' on the metal.  This coating is tough and seems to be waterproof .. it protects the whole exup area and prevents rust and rubbish forming on the cast iron parts .. as well as around the steel bolts  (they come out easily, the oil is not a problem)

The coat ends up looking Matt Black .. so visually it is a lot better than the rusty versions.

Best to also replace the original Yammy Bendy Bolts and get some stainless steel bolts fitted .. but a regular coat of Olive Oil really does seem to save a whole load of trouble  :lol . 

I have talked to Mike GTX (Falcon 269) who worked his magic on all my bikes and lives just down the road from me) about this 'Oil Painting' idea .. he seemed to agree that it was not a bad thing to do .. got get a 1" brush today.

I think any vegetable or mineral oil would work the same .. but here in Spain the Olive slippy stuff is very slightly less expensive  :eek  Try your corner shop  :rolleyes

Worth a thought .. maybe?  Stay Safe Peeps      Trev    (The Polar Bear)

Right, epic day of drilling bolts out and tapping the holes again. done a rather good job in my opinion 
had to take the collector box off to do it proper so cant put it back on until the new gaskets arrive. at least i can prep everything like cleaning and greasing the valve.

I did consider welding a plate over the end to just eliminate the valve but was unsure how this would affect low don torque. i then noticed you can buy an after market one with this already in place.

Anyone done this at all?

cheers,

If the valve is removed or siezes open, then it feels really flat below 6-7 thou rpm then behaves normally. if valve siezes shut it goes ok (ish)  up to say 4-5 thou then feels strangled. Keep the valve and service it properly and the bike is a good 'un

it would be interesting seeing how those downpipes fare against a standard working downpipe,as the ones listed are 4-2-1 rather than 4-1 the 4-2-1 would give a better midrange but not as good as a 4-1 at the top end.also looking at those pipes the shape where the pipes join look more efficient as on the oe exhaust the exup in its own right can cause a slight disturbance in the gas flow plus the oulet pipe is to one side,i dont think the oe exhaust is the most efficient in design

Sandy exhaust headers?  Don't waste your money.

solorider!!
          Jeez mine were in no way as bad as yours! I'd have gone straight to the blue spanner with them (Burning torch).  Mine were easy apart from one stud shearing, got about 20mm left to play with so not too bad.


FuZzBom,
          When I first got my Fazer the valve was stuck shut and it ran awefull, gutless at high revs.  I cant imagine for one minute having it open continuously would let it run well at low engine speeds. It made a massive difference when I first experienced a fully working exup valve, nuff power at all times! That's why we love em innit?  The one listed on eBay looks like it would make the engine sing on full throttle but I just wonder how often your full bore caning the bitch till she screams no more and the front wheels just coming back down while you snick it up into fourth....or summat you louts on bikes like to do. I myself ride like nun carrying eggs (not in a reproductive way, I mean like Chickens or Ducks if you fancy).  Anyway I'm off work sick so I gotta bit o time to type.  So I have, typed. I'm off for a coffee and to stare at the phone while waiting for k tech to ring and say my shocks all done


:rolleyes :rolleyes

Hi Rich, to be honest that was what i thought. i had a TZR125 back in the day with a power valve and the difference was night and day when i fitted it.
was just curious if the mighty 1 litre could cope with The reduction in back pressure but guess not.
I would also guess it will make it consume more fuel being open all the time.

I am not the fastest rider in the world so the thing howling up in the rev range would soon annoy me. this was the main reason i went from the 600 to the 1000 in the 1st place.

anyway.. you will all be pleased to know i have now fitted it all back together and it seems to work OK. i didn't get the chance to ride it last night because it was nearly 10pm before i got done and cleaned up etc.
I will go out for a ride this evening and see how it fairs.

BTW Rich, get well soon...

The hassle youve had was down to previous lack of service(out of sight/out of mind?) BUt youve got a low miler and the next time you check the EXUP it will be a delight to work on.Strange how Yamaha fitted a nice sophisticated power valve and tried to save a few pence on bolts made of cheese. That valve will be one of the reasons you are going to ENJOY YOUR FAZER
