Might be a silly question, but.... What are the odds that there is no FI or check engine light after removing the stock Exhaust and installing a Werkes GP pipe? I did leave the servo in under the seat, but obviously removed the cables and stock Cat. Converter & muffler.

Victors is on it! 100%.

You need to read back 13 years worth of threads on this topic. The older bikes did not come on right away. Not sure where you're getting your info. But the answer to your original question is still 100.000%

Interesting... So then, does the ECU assume the servo is wide open, or closed? Does that affect rich/lean conditions? Hopefully getting in to Guhl next few weeks to have it flashed & tuned, just curious how much is affected in the meantime.

:headshake: Ugh. This thread is headed to the trash bin soon, I can tell. So much is wrong here. :heyyou:

If you leave the servo in place, the ECU doesn't know anything is different and no light turns on. Your 2006 636 was the same way until you took the servo out. The ECU doesn't assume anything other than the system is just fine. Therefore there's no fueling differences from the ECU. The airflow will be different and the stock tune is based on what it senses from the O2 readings and is based on the exhaust valve and catalytic converter in place.

You also didn't remove the stock "exhaust". You removed the stock muffler. If you replaced the whole exhaust then you had to screw with the O2 sensor and would cause all sorts of shit to happen. The "exhaust" is the complete system made up of the head pipe, catalytic converter, and muffler. You didn't remove that, only part of it. And if you left the servo in place, the ECU still drives it and you won't see anything. So,
"What are the odds that there is no FI or check engine light after removing the stock Exhaust and installing a Werkes GP pipe?"
= 100% no

Actually, you're wrong, the FI did set just from removing cables on the 636. I know, I was there. I didn't remove the servo for 4 days, until the servo buddy came in the mail. Like magic, the FI light went off.

And my bad for offending you with the term "Exhaust" as in everything but the "Header", unless you prefer "manifold". 99% of people do not purchase that component, as the performance vs. Cost is not worth jack to them. Therefore, we call mid pipes and slip ons "Exhaust". You sound like you may need a snickers good sir. Or maybe a nap. Enjoy whichever you choose. ?

:lol: I did need both the snickers and the nap. More so just the nap! :mrgreen:

The 636 issue is something different of course, but it doesn't make sense that the servo buddy removes the FI light when it just replaces the servo drive unit. So if the servo was still there and you got the FI light on, then the servo buddy is just emulating what that units does. :dontknow: But that's a discussion for another time. Carry on!

The 636 bike would set a light if the cables were removed. You had to replace the servo cam with a new one that would trick the servo motor into think it was still hooked up. Muzzy wpuld include it with their systems as would most other exhaust companies.

Removing the cables on the 10rs will not set a light... the ecu will not run richer or leaner or anything else that would need to be addressed... at all. Will the bike benefit from additional fueling changes because of the exhaust changes, sure but it's not mandatory.

I'm assuming this is your second bike and this will likely be the first one youre really getting into technically speaking.. I had an 05 636 that I just didn't know much about other than doing a slip On and the euro jumper mod.. and I'm now on my 3rd 10r and still lesrning. Sorry.. it's frustrating for most of us when questions like this get asked in the way ones like this are worded. We simply assume that everyone should know how this works already when thats not the case. I still ask questions, despite having had 2 years of classes at an actual school on the subject (not those crap tech schools who don't actually teach you anything) and I can tune and run a dyno (been trying to find a job doing it for bikes and not cars for once). So... anything else you need to know, no matter how simple or basic the question may be.. we will try our best to answer it for you.

it's actually my 7th bike, but newest by 10 years. I've done way too much in the ways of modding them all. But, most of the time, I buy all kinds of stuff, and do a lot in one shot. This is only the second time I ever just did a pipe, threw me off that it didn't set a light like the 636 did, and there is next to no info out there on Gen 5's just doing pipes, So, figured I'd ask. Thanks for the replies.
