valve

I reconnect the flapper valve when taking the bike to the dealer for service work and last time when I did it I could not remember which hole to put the cable end into. This is the correct position in the photo so just thought i would share here on the tech section for anyone else that ever...

are there any technicians out there that have done the AIS activation test on a 2012 1199S with racing evo upmap and full termi exhaust? During this opening and closing cycle of the valve, the system monitors the injection time piloted by the ECU with active lambda control. The difference of...

We all know our bikes have this insanely expensive valve check job "requirement" every 15000 miles.... is this really necessary??? I mean if you could clear the Desmo Service indicator and just continue to ride... would this be injurious to the bike??? No doubt its recommended... but...

Ok, So I just got done reading another thread on the 15,000 mile service which brings on the dreaded valve adjustment and cost for it. My questions is this, has anyone attempted to perform a valve adjustment in their garage? My buddy and I have done ours in the past on his 998 and my 999...

can anyone let me know the original position of the cable on the exhaust flapper valve. Just reconnecting mine (don,t ask why, long story) and there are two holes for the end of the cable to go into the circular actuator. Looking from the chainside - is it the hole to the left or right ...

I'm currently at the Nurburgring and have the nightmare of not being allowed on today due to me hitting 104db static. I need to try and get it below 100db static so wondered if there is way to close the exhaust valve for the static test. I'm going to try again tomorrow but 4db is pretty...

is both the 1199s and tri color got the servo control exhaust valve? i heard that tri color got the servo, but the wire is not connected to the valve which means the valve is all time open? 1) if yes, is it because of the different exhaust? 2) what is the exhaust different between the tri...

There have been at least a couple of threads regarding the closure of the butterfly/flapper exhaust valve between about 2500 and 3500 revs, for those with stock exhaust, and the resulting power loss and potential surging. One here...

So I have done the exhaust valve mod involving disconnecting the cable, however, now it seems I am experiencing some issues that I didn't have prior to disconnecting the valve. Wanted to see if anyone else was experiencing similar issues"¦or am I just imagining things. Since disconnecting...

Has anyone noticed the flapper valve is open at start up (when it should be shut to help noise tests) and then at around 3200rpm it shuts when cruising or going down hill and only opens after you open the throttle some way which causes it to suddenly open and lurch forward! not good and is a...

Is this piece of stock kit for meeting sound regulation or they really have a contribution to engine performance? Was thinking if it could have some similarities to variable (or in actual fact 2 step) length intake manifold like found in past R1,MV F4,aprilia's V4...to optimize speed of...

Rode about 100 miles on my 1199s this past Sunday and had a curious thing happen. At three or four random times during my rides, I lost the beautiful exhaust sound. Happened at random times too. Once during acceleration from about 40 miles per hour, another as I was coasting in 2nd gear. Was...
