Heh, Beemer on a tow truck, nothing new there.
Just connected TuneEcu to my 690R and noticed that it has loaded the 2009 stock map., however the bike has akrapovic exhaust, foam aifilter and powerparts airbox cover, does not stall, sputter, backfires, or anything.
Shouldn't it act all fussy with these mods and stock map?
It shakes a bit, nothing excessive, but its a single cylinder...
I'm almost inclined not to touch it rather than loading the akro map. If it gets better, it gets dangerous...
$10 says its lean, especially higher in the revs.
I tend to agree... next weekend i'll give it a try with the akro map then... which one BTW? In the TuneEcu site there is an all years Akro map and a evo1 map..
Can I fit a 690 enduro 12 light and surrounding plastic to my 690 R 2010?
OK need some help again. Backstory, I had the fuel pump replaced in March, then it started smoking so I replaced the piston and rings. I rode it about 60 miles and shut it off and it wouldn't restart, then it bound up. I pulled the valve cover and the wheel pin worked its way out of the intake valve rocker and was interfering with the exhause rocker.
I got it back together today and it started quick enough but is running like crap and sometimes won't start at all. When it does start it runs rough backfires a little, won't idle for long and if I give it throttle it bogs like a carbureted bike when it is still cold.
The only thing I know to check is the cam timing for the 3rd time. The engine light is not on.
I'd try to get some wideband O2 readings so you actually know what the bike is doing under load at various RPMs.
Running rich can create just as much damage as running lean.
I recently replaced the stock can on my 690 with the FMF Q4, and after examining the bike post ride, noticed the FMF was loose, even though the bolts are as tight as they can go. The FMF mounts via only one side of the exhaust mounting bracket. While the rubber grommets in the mounting bracket may introduce some play, they are likely present more so to decouple the pipe from the tank (shock absorption). If memory serves, the stock pipe was rock solid.
Anyone else experience this, and have a working fix ?
Tighten the clamp on the pipe, I have the same exhaust and its solid. Ridden all kinds of nasty with zero issues. You might be doing it wrong
(as the upper mount is riveted/siliconed to the pipe, and hence cant be tightened) How tight should the lower pipe clamp be ? I cant see the lower clamp being primarily responsible for rigidity, as that would put alot of stress on the header...
A loose exhaust is probably worse than a tight clamp, think of the weight of the muffler moving around. Think of it like a slide hammer.
Tight man, can't explain it..
Tighten I have, and she now feels much firmer. I'll slap myself for thinking the upper mount would/should bear the brunt of the weight....
Start off checking the injector. Sounds like it could be fuel related. is the pump cycling when powered up? I know you replaced the pump already, but I'd start with fuel, and spark.
Honestly it is acting like the pump but I don't want to go there. The pump is making noise. I checked the spark before I put it all back together. I guess I'll study up on the injector.
That's where I'm at right now also. I cleaned mine myself, and the 690 fired up all sweet like (previously was not starting at all) but it does stall. Changed the fuel filter, recleaned the injector and and runs poor. Stalls when decelerating/stopping, and misses when accelerating. Holding Rpm, it runs, say doing steady 80 kph, or higher. But crack the throttle and it misses.
I have checked spark, wires, everything I could myself and taking the injector out and putting it back in was the only item that resulted in a positve.
So now today I'm in the process of finding someone to do the "ultrasonic" cleaning? Or at least at more "proffessional" cleaning than I gave it. Funny though, the shops I've called so far seem to do the same, homemade cleaning style that I do, just blow air backwards through it.
Once I can rule out the injector, then I'll look at a different part I suppose...but I think it's got something to do with it...
Agree, although finding such equipment with qualified technicians around here is quite a task.
The power wires going to the coil, the 2 spade connectors, were very corroded on my 2010. The gauge size is too small. I was have similar type of problems, it would run great, than barely idle or not start at all and no pattern to it. Just something else you may want to check
I had the same problem on my 09 690r. Seemed like a fuel problem but it was those blade connectors on the coil being a little loose. They were not corroded on my bike but crimping them for a tighter fit solved the problem.
