thruster8999 Posted August 25, 2016 Share Posted August 25, 2016 A much belated thanks for the offer thruster8999. I just ordered one, been running around all summer playing Mr. Mom for my girl missing all the prime riding So I should have this on in time for the fall season. With a little luck we will be enjoying riding into november. No problem. Let us know what you think. Link to comment Share on other sites More sharing options...
zimbob Posted August 26, 2016 Share Posted August 26, 2016 the surge at low rpm drives me crazy. I drive through a couple small towns with a 25 mph speed limit.At that speed the bike just sputters. especially at constant speed Link to comment Share on other sites More sharing options...

zimbob Posted August 27, 2016 Share Posted August 27, 2016 Too funny I kinda thought that as well. I had a 1974 DT 175 that only ran smooth at full throttle. Link to comment Share on other sites More sharing options...
docsimple Posted September 16, 2016 Share Posted September 16, 2016 well, install went pretty easy. A little more involved than the instructions as they were for the fz09. Just removing fairing parts. Looking forward to the test run tomorrow including some tractoring off-road. Gotta get one more night in the mountains before the rain comes 2015 Red FJ 09 2013 WR250R - little boy blue - sold 2012 DL650 V Strom - sold 2007 FZ6 - sold 1986 FJ600 - sold Link to comment Share on other sites More sharing options...
crempel Posted September 16, 2016 Share Posted September 16, 2016 I'm curious to hear your thoughts. I am considering it too. Did you go this way instead of a flash or did you do both? Link to comment Share on other sites More sharing options...
caferacer Posted September 16, 2016 Share Posted September 16, 2016 So what do you think?? My mods are 2bros full system, k&n filter and will be installing graves block off plates this weekend.....re: after installing the exhaust and filter I have a dead/surge spot around 5500 rpms that is driving me nuts!!! Are you still having problems wit the dead spot? You're the first I've heard to mention replacing the Yamaha air filter, sometimes the manufacturer gets the airbox right, it may be more than sufficient. I say this because on other bikes I've "upgraded" to a K&N only to find it just adds a lot of growl and a dead spot. Link to comment Share on other sites More sharing options...

I say this because on other bikes I've "upgraded" to a K&N only to find it just adds a lot of growl and a dead spot.Yes I do still have the dead spot but its very minor now in standard mode and almost gone in A mode. IMHO the O2 controller is a must if your not flashing the ECU and you want to smooth out the throttle. Interesting find about the k&n air filter...I just may swap it back out to the OEM and see what happens. TY for the info, gotta love this forum!!!!

docsimple Posted September 16, 2016 Share Posted September 16, 2016 I'm curious to hear your thoughts. I am considering it too. Did you go this way instead of a flash or did you do both? I am trying this as a stopgap. If its good enough i will leave it alone. I occasionally get annoyed with the speed limiter but to be honest this bike is not crazy about going super fast. To be honest my 2007 FZ6 was way more stable. So I may not bother with teh flash if this is good enough. Anyhoo I'll report back after this trip 2015 Red FJ 09 2013 WR250R - little boy blue - sold 2012 DL650 V Strom - sold 2007 FZ6 - sold 1986 FJ600 - sold Link to comment Share on other sites More sharing options...
thruster8999 Posted September 16, 2016 Share Posted September 16, 2016 I havent had any problems or dead stops with mine except when it is cold. Still have the factory air filter as well. Link to comment Share on other sites More sharing options...
pfontainejr Posted September 16, 2016 Share Posted September 16, 2016 I havent had any problems or dead stops with mine except when it is cold. Still have the factory air filter as well.Just to be clear, my dead/hesitation spot around 5.5-6k rpms appeared after the exhaust/filter upgrade. I will try caferacer's info on his past experience with K&N air filters and just swap back to the OEM air filter and see if that is the issue (very minor now with the O2). The Kev mod O2 controller helped a ton and I highly recommend it! UPDATE: re-installing the OEM air filter worked...no more dead spot!!! A BIG TY to caferacer!

docsimple Posted September 17, 2016 Share Posted September 17, 2016 So I give it an 7/10. It really does help a lot but I noticed a dead spot as well. It seems to be around the transition point from closed loop to open loop. Also this does not ameliorate the throttle snatchiness. I believe an ECU flash would fix that better, but I have never tried a bike with a flash. Has anyone tried both this mod and the ecu flash for comparison? Don't get me wrong, for the price and ease of installation its well worth while and i would do it again. 2015 Red FJ 09 2013 WR250R - little boy blue - sold 2012 DL650 V Strom - sold 2007 FZ6 - sold 1986 FJ600 - sold Link to comment Share on other sites More sharing options...
Premium Member 1moreroad Posted September 19, 2016 Premium Member Share Posted September 19, 2016 Maybe a stupid question, but here goes: I had in mind that this replaces the OEM loom. Does it actually hook up inline between the sensor and the OEM loom? Link to comment Share on other sites More sharing options...
docsimple Posted September 19, 2016 Share Posted September 19, 2016 1more sort of. it plugs into the existing plug which you move up under the tank. Their wiring then runs down to the O2 sensor and plugs in. THe wiring looks different than stock but its black mesh and not noticeable. 2015 Red FJ 09 2013 WR250R - little boy blue - sold 2012 DL650 V Strom - sold 2007 FZ6 - sold 1986 FJ600 - sold Link to comment Share on other sites More sharing options...
Premium Member 1moreroad Posted September 19, 2016 Premium Member Share Posted September 19, 2016 That's what I was starting to figure out. Bad assumption on my part. The OEM loom disappears into a wrap of wire harnesses. Now it's done. 20160919_124954 by gcsurb, on Flickr Edit to add: Back from a 20 mile ride with a few corners and a fair amount of traffic. This makes a huge improvement in small throttle opening/low rpm drive. The bike is so much smoother the way I usually ride it that it feels like a suspension upgrade. I've ridden javashot's bike with his reflashed ECU, and this is every bit as smooth. The motor was great before, but this is much better. Link to comment Share on other sites More sharing options...
