Does anyone know how to differentiate between a 250F coupler and a 450F coupler? I have some extras laying around and not sure what they go to. I've had a lot of Kawi's.

The physical plug does not store the map at all, and im sure the plugs are the same between 250/450.

The ecu sends a reference signal through the circuit to the "mapping coupler plug". Depending on the resistance of the plug, the ECU receives a voltage back. From this return voltage it knows what map to run. I am not sure of this, but I would be willing to bet there are only 3 voltages it recognizes. IE: you couldnt measure resistance of the current 3 plugs, and then alter the resistance of the extra plugs you have to create the ability to store additonal maps that could be run via these new resistance values. Basically these resistors just serve as a look up to which map the ecu should run thats stored internally.

You could probably just wire up a Map switch to the bars, with each resistor on its own leg. I dont believe the bike would recognize a change on the fly, but it would allow you the ability to pull over, shut bike off, and flip switch to different position and restart bike without having to go to the pits and change the plug.
Thanks, so I should be able to use the coupler on a 450 regardless of whether or not they came with a 250 or 450?

My 17 needed remapped. It was detonating in colder weather. I sent it to Tokyo mods and had them do it. It's much better now, also it doesn't pop on deceleration anymore.
I just picked up a 17 but haven't ridden it yet. I was curious if the 17 still popped any. Were you all stock on pump gas or do you have a pipe and fuel?

Be careful with that,if they aren't right. Why not just buy the correct ones. ?

Well I don't really use them. I am about to have my 450 remapped anyways. I just found some in a drawer and I wasn't sure how to tell the difference. So I asked here.

I still have a 250 and a 450, so just wondering. My 250 is already mapped so I wouldn't change couplers on it anyways.

Plus, what DMM698 would kind of make sense to me anyways, the couplers look the same, without taking one off the bike and trying to install the extra ones I have. They look identical between both bikes. If they were different wouldn't kawi think ahead and make the plug a little different? Certainly they know that people will probably have 250's and 450's under the same roof. So the resistance theory makes sense.

Are they marked?,. If you don't use any couplers, it will be on the stock map. Fyi.

Just verify the pins are in the same locations, cant imagine they wouldnt be. Then just test resistance across the pins. The green plug from your 450 may be say a resistance that would drop voltage to 2 volts instead of 5, (V=IR). This may correspond to say like the white plug from your 250 . I highly doubt they would change this but you can check easily if you're concerned.

I think it would be cool to do a map switch now that I think about it even if it wasnt on the fly. Wonder if anybody would be interested in this.

It was all stock on pump gas. It popped on decel all the time and ran lean in colder weather. Remap took all that away. Seems to start easier now also. well worth the $100.

two things

1) I purchased a Race Tech spring fork conversion off of Vital Bazzar for $350 with the spring. Best $350 I have ever spent on a dirt bike.

2) before sending my ecu off for re mapping I did a bunch of research and found that people were finding there TPS (throttle position sensor) out of tolerance and causing the decal pop. I found mine off and adjust it and low and behold the pop is gone and throttle response is crispy! procedure is in the service manual. Pretty easy if you know how to use a volt meter.

Just for the record, I have confirmed that the 250F and 450F map couplers ARE the SAME. Just making note in case someone else has this question down the road.

I would also like to note that as of now, TLR needs your whole bike to do a remap on the 16/17 Kawi. Todd does not have the harness needed to map the ECU alone. So I am sending mine to Tokyo Mods.

Thanks!

Does anyone have a PDF version of the 16/17 service manual? Hate to ask but I have searched and searched. I know someone has it.

Did you not find it or do you not want to pay for it? If you had trouble finding it, here is the link.

My TPS on my 16 was definitely low as well. My post on TT might have been one that you came across. I bought the TPS connector from an automotive electronics guy in NJ and made my own harness to jump into the TPS with to make "probing" a snap. If anyone needs the info on the connector, let me know. I'll go find the guys site and get you the part numbers.

eBay, local kawy dealers $60-70. Best $$ spent.
2/15/2017 6:41am
I'd prefer to not have to pay for one. As much as we pay for these bikes, they should come with one!! But that's a different discussion.

If anyone can help me out my email is mxryder119@netscape.net. I am mainly interested in checking my TPS.

Thanks.

Try that ransome guy who's building the 500 hybrid. He bought a new subframe to use for a mock up for his titanium one he's made. He was selling it.

Already tried that. He's an asshole. But I ended up getting a brand new one for $350 from someone parting out a new 2017 on eBay.

Thanks anyways.

I rode the bike yesterday at a local practice track and put almost 2 hours on it. Here is my impressions on riding it totally stock.

The forks are way better than I had expected. I was quite surprised by how well they worked. So was the 44 year old former pro I let ride it, who is still crazy fast. He had a 15 and sold it because he hated the bike, and especially the forks. When he saw me pull up with this he was itching to ride it though. Both of us felt the suspension was damn good out of the box with just a baseline setting. I ran the forks with 160 psi in the inner, 14.5 in the outer, and 175 in the balance chamber.

This bike handles very well and really wants to lay over in a corner without much effort.

The stock tires suck. I'm gonna throw on a set of Dunlop MX3S.

The clutch is meh. Will be adding stiffer springs for sure.

The brakes are good, but a bit spongy. I have Galfer lines on order and that should fix that.

The ergos are fantastic. I moved the pegs down and the bars forward in the clamps, but spun the mounts around so it's not all the way forward. I felt natural on the bike right away. After two laps I felt like I had been riding this for a full season.

I forgot how good 7/8" handlebars feel. I think I'm gonna keep running them.

The grips are made out of concrete. Terrible. ODI will fix that.

It's geared too tall, like I suspected from riding in the yard. 51T rear will be here soon.

I only heard the bike cough or pop once or twice all day. Even with the pro on it There was no issue. I ran it on the black coupler with 93 pump gas. Gonna try the green one out next time.

The bike is fairly quiet for a Kawasaki, but still not as quiet as my friends YZ250F or my other friends RMZ450 with a Yoshi exhaust. At least it didn't sound like a 2010 KXF. Still though, I'd like to put a different silencer on it to get it a bit quieter. I hate loud and obnoxious four strokes.

All in all, it was a good day and I'm happy with my purchase.

That is consistent with what I have learned over the past few weeks on my bike.

I have been running the stock green coupler with good results and tried the white one to try and make the 50T rear sprocket work in more conditions with not very good results. My motorcycle has a PC re map ECU and I can still get it to pop slightly on deceleration. With the white coupler in it made it worse and I was running Sunoco 98 unleaded non ethanol which is the lowest octane fuel I can get in the area with no ethanol.

I am very close on my air pressures and with the FC re-valve the sweet spot seems to be 155-158 inner 10-12 outer with 203 in the balance which are lower than what FC recommended for me. I was having some issues with the front climbing out of ruts, probably rider error, but I fiddled with and adjusted the rebound in the forks and it was much better. Overall I like the forks, but still think they are a bit of a pain in the ass as they are not consistent once you start riding and pressures fluctuating.

Overall I love the motorcycle, this is my first 450 ever and I really like how easy it is to ride, how it handles, its easy to start and jumps really neutral in the air!

4/17/2017 9:18am
Man, you guys are both running some low inner pressures there..
