I agree with you in that the idle motor/compensator could cause an erratic idle & stalling. Has anyone tried unplugging it? Obviously the engine warning light would come on.
I just ordered the Wuka booster and now patiently awaiting for it to show up at the door. My Terra has been Mossed by the dealer but it still wants to fall on its face around 3k. I'm really hoping this takes care of this issue as well as the occasional hiccup, cough, sputter and stall that still seem to be happening.
I think I'm going to kick the can to the curb while I'm waiting for the Wuka to show up. Sounds like a plan.
Why does it run better without the canister? I've had mine mossed and the Wuka installed. It seemed to be running pretty well until this high heat showed up around here. Now it's back to it's old tricks.
the canister has some stupid electronic valve on it that controls it and allows pressure to build up and then release. Dynojet found even completely stock bikes would build a lot of pressure and then release and could see it jacking the idles all over the place.
I am very temped to try that at some point. Maybe remove it all together. Might mess with it some day when I have some spare time which seems less and less.
Ok, canister has been removed. Thanks a bundle to High Five for providing such a detailed, documented procedure. Due to his post the procedure was straight forward, easy and quick. Removing the plastics and putting them back takes longer than actually yanking the can. So I took the Terra out for a 15 mile test ride to see if I could notice a difference in the way it ran. I didn't have any hiccup, cough and sputter that so often happens but it's still a little dumpy around 3k. It doesn't seem as bad and want to fall on its face at 3k though so I think it was definitely worth my time. I'll know more after racking up some more miles. Now I'm just waiting on the Wuka to arrive. Got my fingers crossed that it will cure what ails me.
I think the most single improvement/upgrade we can make to our TR's is to install a Booster Plug or Wuka.
MPG after Wuka Booster Plug Just completed a 430 mile, one day "Iron Butt" Cascade Loop Ride over two mountain passes up to 5500 ft elevation from sea level. All pavement. Winding mountain roads. Weather: Hot - 90's (Red setting on Wuka) Performance at elevation: outstanding. Gotta love fuel injection. The carb bikes struggled. MPG: 62.5 MPG average; 64 MPG best Comments: I made the same run earlier in the year before the Wuka and got 58+ mpg average. To be fair, I had full camping gear and Happy Trail Teton panniers on then. No panniers this time. That said, the MPG is better than before Wuka, which surprised me. As usual, the Terra just purred along at highway speeds, even while climbing over the high passes. The stock seat was tolerable with my butt about as sore as if I sat in a folding chair for 10 hours, but not painful. I would say better than my KLR 650. I think borderline for a seat upgrade.
I installed a Boosterplug on my Terra and now its running as it should have done from factory. A real improvment of drivability and throttleresponse. The best spent money on the bike this far.
I mounted the booster plug. Actually performs the miracle, disappeared unwanted shutdowns. For the rest I have not noticed any difference. But I have a doubt, when it gets really cold, during cold fear too will enrich the mixture. This fear can do flood the bike. Some of you have already tried it with cold temperatures? However, I have assembled to see if the plug would solve bosteer because my mechanic told me that there was still a solutione by husqvarna. solution arrived by magic after threatening via email the parent. Friday will bring the bike to a mechanic then I will tell you. Ho montato il booster plug. Effettivamente fa il miracolo, spariti gli spegnimenti indesiderati. Per il resto non ho notato differenze. però ho un dubbio, quando farà veramente freddo, nell'avviamento a freddo temo arricchirà troppo la miscela. Questo temo possa fare ingolfare la moto. Qualcuno di voi l'ha già provata con temperature rigide? Comunque io l'ho montato per vedere se il bosteer plug avrebbe risolto perchè il mio meccanico mi ha detto che non c'era ancora una solutione da parte di husqvarna. soluzione arrivata per magia dopo aver minacciato tramite email la casa madre. venerdì porterò la moto dal meccanico poi vi saprò dire.
Is the huge difference good or bad? i.e. does the booster plug help or hurt? (It is *real* easy to forget we are on opposite calendars with regards to weather)
You definitely need to fill the location in on your profile! I am keeping track of places I want to visit...
