    Convention, standard nomenclature? Probably because during 'normal' throttle operation the second cable doesn't do anything but get pushed around.....

    "The linear movement of the inner cable is most often used to transmit a pulling force, although push/pull cables have gained popularity in recent years e.g. as gear shift cables." From here: http://en.wikipedia.org/wiki/Bowden_cable

    I wouldn't say I'm "Hell Bent" on removing it, my biggest issue is the extra drag it creates and the logic of its placement.
    My throttle has never "snapped" shut since I've owned this bike, it always closes steadilly (with bike off).
    I have been dealing with a "hanging idle" as have most others, previously.

    I have since removed the carb, replaced the 160 main and 65S pilot with a 175 main/ 68S pilot, placed B53E needle onto middle clip position and re-assembled. I have yet to start/ ride the bike.
    Upon assembly I tweaked the adjustment of the cables and the throttle returned significantly better than before the tear down.

    I also had even better results with the throttle return with only the single cable connected, hence my questions as to why it is necessary for it to even exist?

    Pro's- can be used as a spare cable, can be used to close the throttle manually if "fail safe close" mechanism becomes non existant.

    Con's- Creates extra drag on system actuation, something else to replace/ buy.

    In summary, I will keep the cable on there, its not causing me any issue at present and its supposed to be there plus I can use it as a spare if needed.
    The back and forth discussion and input from you guys certainly helped me make a decision for which I was unsure initially. I appreciate the comments, opinions and banter....all part of what makes this site the special resource that it is.
    Glad it didn't turn into a sh!t fight, thanks guys.:1drink

    I removed the push cable about 3 or 4 years ago and it's been great *knock on wood*

    I too had a hanging idle issue and it didn't help a ton (maybe a little, but I think it was a kinked pull cable mostly). It's snappy as heck though. I kept it on my 600 though because it has no issues.

    I'm thinking my pull cable might also have issues, would anyone know where to get extended cables for this bike?
    I have 1" risers on the bars.
    Looking at replacing both cables.

    If your throttle is hanging up, you need to fix the issue, not just remove things until it works! Lube the cables and make sure the throttle tube is not sticking on the bars or inside the housing. Remove the return cable and see if that helps relieve the issue. Good place to start trouble shooting but I would not remove it all together, not make if "a racer you know removes his so I am going to do the same" That is idiot logic. I know it was not you that said it, I am just bringing it back up. Good luck with the throttle issue!


    EDIT!!!!

    Sorry, I didnt see they part where you said it worked better with one cable. How does the return cable feel when you run it back and forth by hand? It should be smooth as butter with no hard spots.

    I think they both need replacing, due to the feel of them.
    I did lubricate both cables when the carb was removed, I have a cable lubricator however the only lubricant I had on hand at the time was Silicon Lube, they felt much better afterwards but I still feel they need replacing.
    Just looking at the external tube of the cable, it looks as though its "had its day"..
    They are both 8 years old and still in one piece, once replaced they will both make adequate spares.

    Any idea as to where to get extended cables to suit XR650R?

    I have not had a good search for them yet, best I can find are standard length cables..

    Motion Pro. They will set you up. It may take a couple of weeks, but these guys were very good to work with. I added Rox risers on top of 1" block spacers. They made me some +3" custom cables. Plenty of length to spare...just in case I decide to add some ape hangers some day.

    No, it gets pulled by the carb linkage as the throttle opens and it gets pulled back by the grip as it closes. There are push/pull cables, like the Bowden cable shifters, but these are pure pull. Other wise you would need two of them! :deal

    My cables are adjusted so that there is a little slack in the cables. That helps prevent binding and herky-jerky throttle response (especially on my 950). Twisting the throttle open reduces the slack to zero in the 'pull' cable, increasing it on the 'push' cable. Therefore the throttle tube is pushing the 'push' cable before the carburetor linkage is pulling it. During throttle closure, the spring on the carburetor still keeps the tension on the 'pull' cable, so there is still excess slack in the 'push' cable, thereby the carburetor linkage pushes the cable back to the throttle tube. If something hangs up on the 'pull' cable or carburetor, that's when the 'push' cable becomes a pull cable when closing the throttle.

    So mine ARE push/pull. But I'm not the only one calling them this. :deal

    YMMV.

    Anyone know if a Weisco wristpin fits on a Pro X rod? I know Weisco and Pro X are sister companies... If not I'll just buy a Pro X piston kit. Where is the best price for a Pro X piston kit?

    thanks

    Was just told inner and outter diameter of wristpin and rod should be same regrdless od brand and match OEM specs, is that true?

    Rad guards should fit fine. Tank has to come off to get to the plug and as mentioned it can be a pain to get back on without the right tools.

    There is a new Acerbis XRR tank on Kijiji TO right now.

    You see Sean,
    if you meant to make me jealous with that clip then I'm a afraid to say you succeeded. Not much wood there though by the looks of it, so better wait until you're home again :lol3
    The colours looks like here, could have been here even but for those massive mole-humps - what are they, outcrops, granite intrusions/sills or what? And it was a surprise to see water on top of that dry sandy bit, quite amazing actually.
    Ride safe and enjoy!

    Anybody have any pics of Acerbis 6.3 sahara tank fuel line routing? Specifically with regular black hose and and a brass t connecter. Just need to know how long to cut the hoses. I bought 5/16 fuel line. Thanks for any help.
    Searched and only found pic of the purple acerbis line and y connecter.

    Yeah, I know that's an allowed way, they say you may - but it ain't a good way doing it like this. Better is to wrap the HT line i.e use it working on induction rather than connection, if only for the possibility of messing up the utterly reliable ignition system of this bike.
    And do not mount it in the aluminium cradle on the bars as it will break due to vibration. I ruined 2 in an astonishingly short time, both replaced under warranty though (sterling service!). Mount it away from hard parts (so not on the triples) and it'll be fine.

    I fall in love with my BRP every ride.....

    Did a nice easy 90 mile DS ride today, mostly pavement twisites, and 20 miles of twisty gravel roads.

    I love pitching the back end out on gravel roads in 4th gear. Puts a smile on my face every time.:clap

    that is all....:1drink
