Random Stall – a Silver Bullett or as close as we may get. TR650 Husky

Interesting...

Note that the oem injector has a 25deg nominal cone. Although the 124 injector specs 20deg, the split cones seem to spec the angle between the nominal centers of each cone, with the spray being wider overall than the spec.

Overall, I would guess the 124 injector is in the 30 deg area.

I did a very rough measurement and believe the injector is mounted around 30deg from vertical in the throttle body. Working through the angles and specs, I believe there is plenty of room for a little wider spray pattern without having it spray on the walls.

Absolutely not an expert. But I've convinced myself that it should be fine, whatever that's worth.

I happen to be in the middle of my valve adjustment and took the opportunity to install the 124 injector. Thus, I happen to have a specific interest in this at this particular moment.

Depending on time constraints & budget, it would be interesting to take both injectors to an injector shop and have them bench tested to see the differences in spray pattern.
hasenpfeffer, thank you for taking the time to perform some basic measurements.

Has anyone who installed the injector logged the WOT AFR? I like this idea but think the WOT fueling performance will suffer

The first step in all of this is to determine the firmware version on the BMS-E, the latest version is important

The second step particularly for those who have had dirt though the air box is to ensure the Idle Actuator and air passages are all cleaned

Those who dont have access to a dealer to check firmware version put out a call in the BMW community around you and see who can do an Autoscan with a GS911 and get a copy of it. In terms of both the Injector and the Idle Actuator look to the research and work done by the G650X BM owners they are leading the way on this and learned the hard way

The results from KiwiApe suggest improved atomisation, lots of luck with info from Bosch it is like blood out of a stone, wasted a lot of my time finding data

I get the impression from this post on another thread that KiwiApe hasn't changed out his injector yet; just done the coil change out.

He is testing each component separately and is putting some kms on each before final fitting of both

Fair enough. Just waiting to hear feedback on those who have fitted the new injector.

AUS_TR650. When mine was running like poop I put the bigger injector in and straight up it made a huge difference, (cold warm up splutter/die and over run / throttle on miss - gone) so for the money and simplicity its a no brainer. Since then I have backed up, taken it out and done Pulstars and all adaptive resets (on OSS) and it is running really well. So for those who can get to a OSS Tool, both items are a simple bolt on solution that makes a big difference. I will put big the injector along with Pulstars one day soon but for now its running so well its not the problem like it use to be and installing the injector does take a few hours.

I got onto a tech guy at Bosch in Aus and he was awesome, gave me everything I asked for and more. PM me if you want.

I'm trying to keep up with this thread and I want to say thanks to all for the conversations.
I need to find a shop that can actually tune the bike, though. I had a Booster Plug installed when I bought my TR650, with the hope that I would avoid any of the issues mentioned in this forum. At about 2200 miles, the bike started stalling, mostly on accelleration from turns/stops etc. And it's backfiring a little. Additionally, when it's in the heat (90deg F or more) it overheats. I'm not tech savvy - heck I don't even have a garage to park in - and I'm working with shops locally in Seattle but none seem to know more than the basics, including the local BMW shop (they had no idea the engine has a known stalling issue or what a Booster Plug is).
All that to say: Do you or does anyone have an idea the steps I should take while I've already got the BP in place? I think I'll get it disconnected/uninstalled and start with the ECU/GS911 testing. Does that sound like a good beginning point? Next I can uprade to the Pulstar plug (an easy change) without the BP. Any input on an algorithm re: what order to try these interventions will be helpful. I love the bike and I've invested way too much to give it up!

Note that you have one of the best dealers within reach up there. Bill's Motorcycle Plus in Salem, OR knows a lot about the TR and would be able to help you out. It's a bit of a trek, but it might be worth it just to give them a call and see what they might be able to do for you.

Its not all about the AFR......

Ditching the booster plug is a good first step, it is pretty much snake oil as far as i am concerned, even on the 650GS which runs mostly open loop it did not do what was claimed

The second step would be get a GS911 and determine the firmware version, if it is not the latest as per the pdf I have on line get it updated by a dealer, that early firmware is a dog and the machines will never run at their best with the early firmware, the GS911 particularly the WiFi version is the only way you can quickly determine faults out on the road.

After that fitting the Pulstar and the injector KiwiApe has sourced cleans up combustion to about the best you will achieve and it will improve not reduce fuel consumption. From there well you can consider other performance enhancements but you will probably just get on with riding a well running machine

In terms of the stalling you mentioned one lesson from the M 650s is look first at the idle actuator, it took us all a while to work that out, second is adaption reset

I'm interested in trying the Pulstar plugs but having a hard time trying to order them. Where are fellow Aussies getting them from? Ordering from US ?

I emailed Pulstar about shipping costs. Got an email reply from someone in Aus claiming to be the agent but my reply emails to him (George) keep getting delivery failures. His web site comes up with dns error, unresolved host name. Googling the Aus. agent's business name brings up some poor service reviews from some customers that have purchased other goods from him.

Here is the Aussy agents details where I got mine from John Riley https://hicloneqld.com/orderform.php to order on line or he can call me on 1800 683 466 or 07 4038 3102.

cheers kiwiape. I'll try John Riley.

What's the bottom line on the fuel injector? Has anyone installed it without any other type of spoofer?

I'm running pod-mod and BMW EJK. My bike runs fairly well. It still has the little hiccup moving from light throttle to off-idle. I want to try the injector with the O2 sensor removed. I deal with a bike shop in town that has a dyno. I'd like to see the WOT AFR with the larger injector. Problem is I have too many irons in the fire and my Strada runs "good enough".
