Reset ecu....with stock air temp sensor in place today. Its running great without the wuka-temp spoof. No stalling yet! and no knocking at all.....great to have a happy motor again. Thanks for the help fellow riders.
Some interesting reading http://www.tomorrowstechnician.com/service-advisor-a-plug-s-life/ Pre-ignition and Detonation Although pre-ignition and detonation are rarely encountered on late-model engine management systems, engine damage can occur if the EGR or detonation sensor system has been disabled, the base ignition timing is incorrectly adjusted or an incorrect spark plug heat range is installed.
I was discussing this issue with a friend who is a long time Ford mechanic and was around during the earlier years of Ford fuel injection. He told me they had similar drivability issues back then and the simple solution was to widen the plug gap which apparently solved the problem. I know others have tried this with our Terra without success but he suggested I try it with an iridium plug because it has lower resistance and would tolerate a wider gap. So I picked up a set of NGK CR9EIX single element iridium plugs and set them at .040 rather than the recommended .024. Short answer result was no improvement and maybe slightly worse running. So I then backed them to .030 and I would have to say again no improvement. I'm still running the iridium plugs but back at the .024 gap. Just thought I'd pass this info along to save anyone else the time if they have this idea. Or welcome anyone else to try the same to confirm my results. I'm pretty much back to thinking we're just dealing with an AFR problem.
Thanks for the experiment information spiderman. I was going to try a different plug but I think you nailed it pretty well. Mine is back to being VERY difficult to start. I am considering going back to 91RON fuel just to lower the activation energy to get it to start. I run 95RON exclusively usually
I finally changed out the new ngk plugs and put in the brisk. Not the cure all, but the flat spot at 3k is gone, and when I crack the throttle to jump speed bumps, I can do it now, without the bog. I'm going to hook up my Lexx now, and use some ejk settings already posted, and see what happens. I may try opening the throttle butterfly before adding the Lexx fuel controller. I did not know what to expect from the Brisk multispark, but they do make a difference, the bike is smoother at 5k rpm. Awhile back I posted up about a vibration etc, that is gone. Most noticeable no more cracking the throttle and falling into the bars and able to launch the bike into the air off of a speed bump. I have not checked fuel consumption per mile, as I only drove about 40 miles today. New plugs installed at 2,800 miles (ref) Torque for plugs is around 7 ft lbs. Because of the 10mm thread diameter, I must stress using caution. They don't feel tight like a 14mm thread plug. Trust that it is correct. DO NOT use anti seize. The Brisk plug uses a 5/8 wrench, the NGK is a 14mm. My spark plug wrench just barely fit into the head with the 5/8.
The spark plug is interesting. Did you get in touch with Brisk for the cross referencing? What part # is the plug you are using?
So I am curious what these do in 1000 miles. I have been chasing bad under load vibrations and it seems when I replace or regap the plugs and reset the computer the right way it goes away for about 1000 miles then comes back. ALmost looking to trade for a ktm 1190 adventure r. Maybe this bike was not designed to do 70-85 mph 60 miles daily? I wanted to put 100k miles on it but I do realize I am riding in the 65%-80% max mph 60 miles a day. Any opinions?
It depends on your aspirations for this bike. We all know it's too heavy for tight trail work. It'll absolutely eat up gravel and spit it out. It's a great compromise bike and is similar in that regard to he KLR, and DR650. It does it all but isn't particularly good at any one thing except secondary and gravel roads. Me, I like fiddling with things to make them work better. I have my bike just about sorted now and I am fairly happy with what is is. I got mine cheaper than most people did so I can't complain.
Brisk told me realistic mileage of about 5,000 is what they see. I'll pull em at 1000 to take a peek. I think so far for me and my riding this is a good remedy. Time will tell. I did hook up the Lexx (dobeck) and not sure. I changed settings in the zones while idling, and it does change things up. I did not drive it. I think with one exception, my bike is near perfect for what I would do driving/performance wise. When idling, if I slowly open the throttle, it will dip off slightly and then perform. If I crack it hard with the dobeck it screams. I don't drive like that, I putter around. Nothing seems to affect that little stutter, off idle. That is why I am leaning towards the idle set screw and a TPS reset. Dang, sure hope that GS911 gets here before I buy the XD500 street "Scramber". Dr Z, on my ride today, I took it on a dirt road. Hot diggity, we have had recent rain, and the roads are not all loose. Cracked the throttle and roosterd right up to 45 in a heartbeat. It is good at that fur sure. On loose gravel, it floats like a boat. Probably the tires, but the weight has alot of impact as well. Still, after driving that nimble DR200, the TR is a bit of a behemoth of a ride. I cannot plant my feet, it is slow to steer and wants to tip over all the time. The 15 tooth sprocket made it nicer on the road, and better than the 16 for the dirt/slow stuff. The 14 was just too low for the road. But yea, bog gone, seemed to start a little easier when warm, probably not going to use the Lexx version ejk. I have plenty power. And will check economy at fillup. $45 was a bit pricey for spark plugs, but one of the better performance changes from stock. I ran the eruption and wuka, and didn't like them. No surprise that I do not brag on the Lexx. I had hopes. I have mentioned before, that I am not convinced it is a fuel issue, plugs point to that. More fuel can get more power if that is what you want, no doubt. But I feel there is something wrong with the air delivery or that initial mix off idle. I may consider dimpling the TB after the butterfly. Probably would have to use a round (bb sized) dremmel bit and lots of care. Only after I have done some butterfly adjustment and calibration. Dang I need a gs911
I just took another ride around the neighborhood. Under driving conditions, no issues, palenty of power, good useable reliable power. I like that about this bike. The idle issue is just when I am monkeying with it at idle in the driveway, I can make it stutter. I think I am leaning towards timing advance, as with the richest settings on the tuner it did not affect that part. And I could nearly make it smoke black with the tuner, well at least I could get it so much fuel it would run rough. Or I could get it to speed up, it definitely adjusts the fuel. Or maybe the TPS is not in sync or sensitive enough at low/closed throttle angles. When I tested the BMW TPS, I could get nearly a quarter turn on the setscrew without changing the tps resistance. And that is where I'm thinking my particular issue is. That surely could explain why the Lexx didn't adjust it out. Today yet again I tried to get at that darn idle set screw. Without removing the airbox, or some super special allen wrench on a cable, just does not seem to be a way to get at it. So, workaround could be bending the stop tang. That is reachable. But still, you would need the moss or gs911 or equivalent to reset/sync things after each adjustment. Could get expensive unless under warranty, but they will not do it under warranty if the computer is not showing any issues. Oh well, next up, economy monitoring with new plugs. Bike runs probably better than most out there, even other than husky. It just don't run perfect. Still a little back poppin some times on hard decel. Shifts decent, better than before, who would have thought that would affect shifting, eh? Didn't have a bad 1st to 2nd all day.
Update on the Brisk Plugs. 1-awesome 2-spectacular 3-best $40 performance upgrade I took her out for a full tank and then some and totally sold on these plugs. Before the plug change I was averaging 60 mpg and had a flat spot/bog at around 3-3.5k. I also had a little bit at off idle. I did not have the stalls as other have, which I did have before the moss. The bike before could not pop the front from a slower speed because when you hit the gas, it would hesitate and nearly toss you over the bars. That is gone, and the flat spot at 3 k is gone. Bike purrs on the highway. I did notice an odd thing about this bike. When going up to speed and hitting around 4.5 k rpm, the motor would vibrate. After maybe 30 seconds it seemed the bike self corrected and got smooth all by itself. It still does not start first pop, usually 3 pops. But here is the final wow ee, 69.1 mpg. No octane boost this tank. My best mileage tank ever. Previous tank was almost 64 mpg. I'm going to see if I can get one for my scooter.
It will be nice to know if mine is an anomaly or if they work with every TR. I damn sure didn't expect to see that kind of mileage. I need to get some trail miles now and see what happens. You are at higher elevation, so you may see similar results. The guys at sea level may never see those numbers. I'm going to have to take a drive and see how she runs along the beach
