2-1, 2-2, kein Plan, war jetzt ne Vermutung, weils bei meiner Virago immer nach CO eingestellt wurde. Die hatte allerdings ne 2-2

die Virago ist ein Vergasermodel das kann man mit der Warrior nicht vergleichen .... und die hat einen Abgassammler .... ist aber egal ;)

Nix Abgassammler. Silvertail K02.

changing the mixture - fuel / air to richer or leaner is straightforward now..gerry or wolfgang will have to translate for me please...as the forum thread harry found shows, you have to find the yellow wire with red stripe down the side..it's grounded at no.27 on the ecu.. which you can see under the wire engraved into the black...do not pull this wire out....what in fact yamaha has done is loop that wire back into position no.29...which is not marked but counts along the wires from no.27 properly, and is in the line above ....this wire has been looped into the end of the loom and when you place the 2 wires side by side together, you can pull them gently out of the loom when you will find it is a proper loop sticking out.....now i have done this and it works ...with the engine off ...you cut this wire in half having marked the wires 27 and 29...and use a male and female spade connection with weather proof covers that go into each other when joined...the 29 will have female on it and the 27 a male...these wires can be joined back anytime to run the bike...to use them to bump the ecu... have an earth wire [say 20amp but it doesn't need to be a thick wire]...fit a male connector to one end and a spring clip the other ..that's it...this earth wire can be earthed to the helmet hook for instance...so with the engine off...undo 27 and 29 at the nerw connectors and fit the new earth lead to 29 [male to female]...and 27 is just left to hang in the air!..it''s ok.....now switch the ignition on...[not engine]...and you can access the mixture readings for C01 the rear cylinder and C02 the front...via the steps set out in the link from devil ...if these settings have not been altered before, they will be the settings made by yamaha for the stock engine and settings ...which should be recorded in the owner manual, so they can be the standard settings to return to if things go too rich or lean in the future - if the stock setings they should be between rear max -7 and front max +1 - usually the front will be 1 or 2 settings [+] of the rear as the front runs cooler than the rear - it's thought 3 increments [settings] = 1% change in mixture - mine for instance were -5 rear and -4 front - the bike was running really well...but it was noticed my front exhaust header pipe was very slightly gold so i bumped them to -4 and -3 ...the gurus insist we should always keep the same difference between the cylinders as the original settings ...+ = richer and minus = leaner...i have noticed the bike isn't quite as good as original even with one bump up each [richer] but i haven't checked the plugs yet to be sure...the gurus pull the left plugs every 60 miles if they have alterd the mixture to check....they use the plugs colour as the guide to the best mixture settings....please note that when accessing the cylinder readings you can go to rear then front.. but have to switch off and start again to re access the rear etc.....you cannot access anything else by mistake by pressing the buttons in this mode so you can't riun anything!!!... once you have read and noted the original settings...when your finished playing.. just swicth off, and undo the earth wire and push 27 and 29 back together and maybe wrap in waterproof tape to be sure....it is that easy wasn't understood...................sorry if this seems long to read...but i hope it helps you as you alter the bike exhaust you might want to make it bike run more rich - cheers tom ;)

my earlier post is setting the mixture with the ecu only ...assuming you do not have a power commander!?...the gurus in rs warrior are discussing if having the ecu settings at say zero will anable the setting of the power commander better...

Arizona Warrior [my best friend Mike] [i call him prof..lol] has asked about this thread..i'm sending him details..as he has better knowledge of the ecu with a power commander set up than me especially with modified exhausts [i don't have either...lol]...hope wolfgang and gerry can pass this on - cheers tom

Hi Tom,
had already been thinking about a Power Commander ;) , but is not the part in Germany legally :shock: , because the engine management is changed and therefore the type
extinguished. But what heck, legal ilegal shit

Greeting Dawel 8-)

greetings dawel - so it was the ecu bump that you wanted to know about...i've asked wolfgang and hopefully gerry to translate what needs to be done for you....that is a surprise - the power commander being illegal in germany!!?..here in the uk we would have to tell the insurance company so thjey could charge us more ..lol...but otherwise it is legal to fit - cheers tom

Ich hab die V&V dran und nie mit dem Gemisch rumexperimentiert. Zugegeben, ist auch nicht unbedingt mein Ding (das rumexperimentieren). Im Gegenteil, ich hab sogar den Eindruck, dass ich mit dem Wechsel vom Ofenrohr zur big shot eine Leistungssteigerung hatte bei mehr oder weniger gleichem Verbrauch.

Habt ihr keine Bedenken, dass allzugrosse Eingriffe nicht sogar schädlich sein können???

für jede weitere Zahl, die Sie bewegen den Ecu Mischung Einstellung ist es nur ein Drittel von einem Prozent [3 = 1%-Schritten zu ändern], so sollte es nicht von entscheidender Bedeutung sein, um den Motor, wenn Sie es langsam

for every extra number you move the ecu mixture setting it is only one third of one percent [3 increments = 1% change] so it should not be critical to the engine if you do it gradually

Ich überlass das erfahrenen Schraubern, in dem Fall meiner Werkstatt. Das ist für mich, ohne Prüfstand, subjektives Rätsel raten. Auch wenns nur 0,33% sind. Messwerte lügen nicht.
