    I did a post on rivet vs clip link for chains on page 513

    Rivet links give 98% strength of original chain.
    I now only use rivet links as I have had the clip ones come apart.

    I like DID chains too, but use a clip master with press fit side bar. I know some guys say they have come off, I believe under hard riding this could happen. For my style which is medium hard off road, I have had no problem.

    Thanks for the chain thoughts.
    I will likely stick to riveted based on responses and what I could read for 650's in general.

    I still run clip link chains even though I lost a clip in Alaska on KLR one year. The side plate had required pliers to get it on far enough to set the clip so the plate was still there. Had a spare clip. I have since used rtv gasket sealer or silicone to glue the clip on the plate and never lost one since. Use acetone to degrease the clip and plate.

    Rain again today so I jumped in and removed the swing arm and happy to say no drama. Even a hint of grease in there!
    Looking at the chains again.......is it a 520 or 525? does it matter? Both sizes come up as matches for the bike.
    Is the 112 endless chain available? I havent seen that listed and assume I will have to press rivit the new one.

    Also I would love a little confirmation on the correct torque for the Left and right side swing arm attachment. Both the cap head screws and threaded bolt had very little resistance in removal. Threaded stud is listed at 80nm????

    As usual thanks for the guidance in advance.

    My Xchallenge has weak power, especially in low RPMs. Also, if I go with a steady throttle and suddenly crank it open, the bike "cough" for a second and then start accelerating.

    Bike has:
    • unifilter main filter, no cover, no pre-filter
    • leovince exhaust
    • boosterplug

    Things already checked/tried:
    • new iridium spark plugs
    • new ignition coils
    • new fuel filter
    • checked the wiring of the ignition coils (both color & cabling)
    • tried to "back flush" the injector and tested it outside the engine - spray pattern seems OK to me but I'm not an expert
    • checked for vacuum leaks - none found
    • valve adjusted and timing checked - OK
    Things I have to check yet:
    • new fuel pump
    • new fuel injector
    I am forgetting anything? A new fuel pump costs a lot of $$$, but if that's a possible culprit, I'm ready to get one.

    Thanks !

    Try cleaning the throttle body real well, and all of the little holes in it, it seems they tend to clog up on these bikes. Also, i could be wrong, but these bikes are also very sensitive to having a good battery, so it would be worth checking and making sure the battery is good

    Thank you - I forgot to mention that I've checked the battery and cleaned the throttle body including the idle actuator, but still no results.

    Is it possible you have bad gas? Some water in it?

    Also noticed this part is being sold by Motorworks in the UK if you want to deal in English .
    19UKP (about $25USD) plus shipping, only need to buy one for this price.

    Well, the problem is there since a couple of months, so I would say it's not the gas

    Is this message for me? Because I already replaced the fuel filter (and noticed a power increase!).

    No advice on the chain other than I've used both types of links for 40+ years and never had a problem with either.

    With that said, never pass up an opportunity to pull the swing arm and inspect it. It's not hard to remove if done frequently and a bearing gone bad is a pain to replace. Experience talking...

    Nice, do these filters require a little modification as per Terry's post somewhere around here??

    Something to do with cutting of a nipple, sealing a flange, trimming an edge etc... :D

    Off to score some KTM wheel nuts now.

    BTW: I'm looking for XChallenge spokes. Full sets front/rear with nipples if possible. Looking to do two sets of front and rear wheels so if you have any doing nothing I'm interested !

    Cheers, Ard

    Hey Dutchgit,
    Does the KTM fender help?
