just got a 675R 2016 and ordered the Coffman exh/tip, whatever...
when I rip out the valve control wires from the original exhaust, is there anything else I need to do ? saw something called servo buddy on ebay...is that necessary to fool the bike into thinking the valves still exist?
I put an Austin racing slip on on my bmw s1kRR and had no issues after taking down the valve control on the exhaust and didn't have to put anything extra....
Hi Jjrho, I believe you need the servo buddy so it doesn't give you an engine error code. I also have a Coffman exhaust and think it looks the part. Enjoy you bike
hey I am thinking about getting the coffman slip on too. Did you have to remap when you did your bike? Mine is still the stock exhaust and set up. It is a 2013 if that makes a difference
ok, so, what if I just take the cables off the servo and let the servo just sit there.... then I won't need that servo buddy thing right ? I did same thing on the bmw s1000rr, put a shorty slip and removed the oem valved exh. and took the cable off the servo but left the servo in.... the servo weight is negligible vs the exhaust I am removing so...
am I right on not needing the 'servo buddy ' and no FI light of CEL on , if I just remove the cables and leave the 'servo' on the bike.... ?!??
Someone with a '13+ will have to verify, but on 06-12 models, if you removed the servo wires the valve would remain closed. Had to safety wire the valve open. Guessing the same idea here.
I am also curious, so I ordered a exhaust and will be putting my input later next week. I believe you can leave the servo motor in, disconnect the wires and still receive NO FI light. IF anyone else has a answer for this, let us know so I can order a servo buddy sooner.
You really shouldn't just leave the servo and cables disconnected as the servo motor is actually quite heavy and it's easy to remove it all. Be sure to install a ServoBuddy or ESRM-2 (which is cheaper) and pull the wiring up under the tank. Otherwise, you will get a CEL error. Here's a link for the ESRM-2:
*removing the cables not the whole thing is what we are talking about. ESRM-2 is a good option if someone wanted to remove the whole thing vs the expensive servo buddy.
** tested - may or may not work - just buy a servo buddy or esrm-2 instead of wasting time
- did not work for me soo beats me if i did something wrong i dunno. **
