    Taking my 690 for it's first long voyage over Memorial Day to Moab, read through all the threads here and came up with a few main issues. Which of these do you all with experience think have to be addressed before I go?

    Tank bolts- yes I read up and know these are a major issue, problem is they are back ordered everywhere for weeks. Should I buy an extra stock set as spares? Anyone have an extra set of the RR ones they would be willing to sell?

    Fuel pump- bike has 1700 miles on it, runs perfect. No issues with starting or bogging. Is it worth pulling it out and cleaning the filter? How necessary is a spare? Am I ok just running some fuel treatment like some have?

    Anything I am missing? Would like to make it there and back with no issues...

    Re-read the entire megathread and repair EVERTHING listed:lol3

    I would check the filter, check all the grounds, check the wiring for possible rub thru's

    Just have the knowledge and a few tools to fix some minor issues and you will be fine

    You have 1700 miles (3000km) on the bike?
    Just take out bolts from radiator guard and ziptied it, and ride.
    Something might go wrong but possibilities it's so little...

    Just ride it and forget about all the hype.

    Unless you've had dirty fuel the fuel filter will be fine, clean it at 5000 or 10000km when its serviced.

    Unless there's play in the tank bolts forget about them until either there is, or you've got it apart for a service.

    I did the tank bolts in the 4 days I had between buying and taking on a 1200 mile OBCDR ride. they are a slightly better design, but as long as you don't let the stock ones get loose to let in some slop, they are fine.

    At 1700 miles your filter should be fine. You may want to take along some filter skins if you are using the evo airbox lid.

    three of us went on the trip, the oldest being an 08 with 10k miles and original fuel filter, none of us had a single problem.


    oh, change the seat and put in super heavy duty tubes.........

    Ok so clearly I cursed myself....took a couple rides and all was well, then the other day I go out and it stalls, then stalls again....now it won't idle for more than a minute without stalling and is running rough and surging.

    I leave for Moab Friday...well if the bike runs. Here is what I have done so far:

    -New battery, original was close to going, figured this might be an easy fix of low voltage, no such luck still not running right.
    -Did TPS calibration (key on throttle up then down and off)
    -Checked electrical connections to fuel pump, no issues I could find
    -Pulled pump, filter isn't black but isn't clean either even with only 1700 miles so I will be replacing this as well with the Napa version
    -Ordered CA cycleworks pump to install as a last ditch effort

    It has an FMF can on it, thinking of trying the stock one again to see if it makes any difference. Other than that I am at my wits end and if I can't get this worked out I will have to cancel the trip :waysad:waysad

    Anyone local have any expertise in fixing these 690 stalling issues or installing the CA Cycleworks pump? Anyone that can check for codes or upload maps? More than willing to pay in good beer...

    Good luck with a timely fix.
    Sorry I can't help.

    Is there a small filter between the pump and the injector? I've heard of injectors that need cleaning. Is it a good idea to put automotive injector cleaner in the gas sometimes?

    My low mileage '08 has just started running less than perfect (low fuel light just illuminated, like 2miles earlier so shouldn't be a factor?, flamed out for no reason when maneuvering, etc.)

    Pull the injector out (keeping fuel line and electrical attached) turn the ignition on and press the starter. It should spray an extremely fine mist of fuel in a cone pattern. If it does not do so, or it drips instead of sprays, (assuming you could feel the fuel line pressurize before hitting the starter) completely remove the injector and backflush it. The easiest way to do this (or at least how I have done it as instructed by a KTM mechanic) is to use compressed air. About 90psi through the nozzle will cause the injector to open and blast out any gunk that may have accumulated in the injector, back the way it came from instead of forcing it through the nozzle.

    I use a small piece of fuel line (you can fill this short section of fuel line with carb cleaner if you like) attached to the nozzle with a hose clamp and the other end of the hose attached to my blow gun. If you put a paper towel on the inlet side of the injector while doing this it will catch any debris that comes out so you can inspect it. After doing this, reattach the fuel line and electrical and double check for a good spray pattern, if it is still not perfect just repeat the flushing process until all is well.

    This has made my bike go from unrideable and unable to idle for more than 15 seconds, to running perfectly normal. All you have to do to access the injector is remove the seat and the airbox, so it is really easy and definitely worth a try.

    Thanks J I will give that a try tomorrow. Have the pump out now and cleaned the screen, was some white crud on it so removed that and will see if that helps too.

    After cleaning and backblowing the injector, I am periodically running injector cleaner thru the fuel system.
    I haven't had another issue with the injector plugging up since, and that was over a year ago I had issues.

    Great info.:clap

    Since I recently discovered that there is a some stuff on the Internet that wasn't Porn, I've been amazed by what I've found.

    (well actually when I thought there was only Porn, I was frequently amazed, but you get the idea)

    A couple of Brigstone vids, and a life long terror of tire changing - cured!

    Blew out the injector, a bunch of blackish crap came out as well as one chunk of brownish stuff that looked like resin. Bike idles and doesn't stall now, rode it for 45 miles and no issue, thanks for the tip Letter J.

    Fuel filter looked pretty dirty, definitely replace that this week given the black crap in the injector. Not sure if I should install the CA Cycleworks pump or carry it as a backup, not sure I would even want to do that job outside of the garage though.

    Now that it has me spooked I noticed some clacking at idle, wondering if it is the chain smacking the case a bit? Anybody else have this type of noise at idle?
