Hello,
Thank you for taking a look at this thread, take the information you may find helpful and use it, and post anything that may be helpful for the problem being expressed. I currently have a 2007 Yamaha FZ6 S2. I recently purchased a de-cat to go with my Delkavic slip ons. Currently the bike has Delkavic slip ons, K&N air filter, and a de-cat from Delkavic.
Upon installing the de-cat I started the bike being completely cold and during warm up it ran perfectly fine. After it was 120f the bike started to lope and the RPMS would jump maybe jump at max 100 and before when warmed up it would never do that. Another thing to add is that during installation of the de-cat, I did replace the spark plugs which were at 12,000 miles. I double checked the seat and click(seating of the spark plug cap) to make sure the bike was not misfiring and I came up with no signs that the bike was misfiring.
IÂ’m pretty in tune with my bike as far as being able to tell when somethingÂ’s wrong because itÂ’s not sounding normal. I read other threads and saw that the lack of back pressure some how makes the bike idle differently? I do have the DB-killers in the slip-ons as of right now. Another thing to add is that the bike is still very responsive throttle wise and doesnÂ’t jump RPM when held at a higher rev. With all the mods that affect air flow, would a power commander be an advised option to fix the loping idle? Does the lack of back pressure have a negative impact on performance? Is it something that IÂ’m just going to have to deal with? I might be able to tell if there was a lack of power but I live in Minnesota, so the option of riding is out of the picture for at least a month.
Thank you reading my post. Please leave a comment if you have any knowledge about this problem and if you were able to fix it .
