    Ray, It is not from the gears our gear teeth are staight cut that bit of metal has a curve in it , can you see if it bends with say using 2 pair of pliers to make it bend or does it snap.
    I t does not look like to me that it came from a roller bearing cage either soet of looks like a bit of locating dowle not sure try the bend test.

    Now main jets the SR/42 ran I think smaller mains because it has more vacume at the carbies because of the bigger volume in the cylinder so sucking more fuel so they decreased the main jet size to componsate .
    they both run the same airbox same aircleaner and BST 33 carbs .
    Technically at full throttle at high revs using 117.5 mains it may loose some performance compared to the 120,s.
    This would burn me up inside knowing that there is extra performance for so little work :D.

    But the only time the locating dowels are exposed are when the engine cases/cylinder/head is apart. How can a piece come adrift if sealed into the case.

    Wait....don't answer that 'cause I don't want to know. I'll be stopping to assess every little weird sound from no on anyway.

    I dont want to give advice on this but can only say I bought a original YZ400F a while ago and like a good boy gave it a oil change after first ride and lo and behold metal fillings in the oil (aluminium I think) was real annoyed but anyway decided to give it another run and change the oil again, same thing, in the end I gave up as decided it wasn't worth stripping so have run it now for about another 20 hrs and it still goes real well and makes no weird noises (other than the paranoid ones I think I hear) Not advising you but it might be part of a tab washer or something and you may struggle to find its source even when stripped ?

    Regards jets My YZ290 had to be jetted down coming from a 250 as more suck more fuel and vis versa, and your altitude is another determining factor, more air at sea level needs more fuel and vis versa (sorry I know you all knew that but just in-case) I would imagine Suzuki would jet bike for worst case scenario so it would not overheat so in theory a smaller main jet should be ok though ?
    Some Carb and jetting links http://www.dansmc.com/carbs2.htm http://www.motorcyclecarbs.com/carbs101.pdf

    Fuel economy, things like time of year (air temp and moisture content) plus grades of fuel can make a big difference so when comparing it has to be apples for apples

    We await Bluesmans appraisal :ear


    Memory lane again (those were the days:D)

    Ladder, may i again draw your attention to the picture of doom that awaited me in my sump

    [​IMG]

    It was from a starter gear, was replaced and the junk was never fished out. It had done thousands of miles with that in it.
    I nearly had a coronary :huh and brought her to a very respected mech for a total engine strip down and rebuild. After handing over the sheckles the mech laughed and told me that it would have been better if i had never seen it as once shes shifting well, and running well these lumps are pretty damn robust:1drink Said he knew as much when he compression checked it before stripping too.

    My humble advice is flush it for peace of mind, change the oil and filter and see about installing one of those dr650 magnetic sump nuts or that magnetic filter ring (or something along that line from procycle) to catch anything that it encounters.

    I'd second what said above.
    Debris usually causing problem IF it block oil ways. In DR it is almost impossible with that oil screen design.
    You remember what I fished from mine when I took it apart first time? That infamous washer that sits on parasite gear - one side had it, other side - nope. And I was sure it is how it should be. Until I removed oil screen to find that 25 mm diameter washer just sitting there.
    FYI- I bought bike and done about 1000 km before I opened it :)

    And it does look like locating dove indeed.

    If it is soft and thin then it may as well be a tab from lock washer which has snapped off. You know these soft metal lock washers with bendable tabs.

    For Ladder106

    HER DIARY:

    Tonight I thought my husband was acting weird. We had made plans to meet at a nice resaurant for dinner. I had been shopping all day with friends and I thought he was upset because I was a bit late but he made no comment on it. Conversation wasn't flowing so I suggested we go somewhere quiet so we could talk. He agreed but didn't say much. I asked him what was wrong, he said "Nothing". I asked him if it was my fault he was upset, he said he wasn't upset, it was nothing to do with me and not to worry about it. On the way home I told him that I loved him. He just smiled and kept on driving. I don't know why he didn't tell me he loved me too. By the time we got home I felt I had lost him completely. It was as if he didn't want me anymore. He just sat there quietly, watching TV. He seemed so distant and absent. Finally, with silence all around us, I decided to go to bed. About 15 minutes later he came to bed as well. I knew he was distracted and his thoughts were somewhere else. He fell asleep and I cried. I don't know what to do. I'm positive he has another woman. My life is a disaster.

    HIS DIARY:

    Bloody motorbike wont start. Can't work out why.

    Cheers.

    Thanks, Lloyd....that was brilliant (and totaly reflects my life)

    Bent the tiny bit with pliers today. It folded to 90 deg then snapped in half. So its not a bendy nut tab. It's hard and brittle.

    Did a 150 mile ride this afternoon. Running well with no odd noises - guess I'll just keep going.

    Glad to hear that it bent to 90 deg. At least it's not case hardened so that rules out gears, valves, cams, rings, etc.
    Just do what your doin', cobber. She'll be right.
    Cheers.

    I looked at the two old drunks sitting across the bar from us and told my friend,
    "That's us in ten years."
    He replied, 'That's a mirror, dipshit." :rofl

    Cheers.

    One of my alltime favorites:


    A priest and a shepherd from Australia participate in a TV game.
    After answering all the questions, there is a tie. So both are given one final assignment:
    It is to write a poem in three minutes, using the word "Timbuktu".

    The priest returns with the fruit of his inspiration:
    "I was a father all my life, I had no children, had no wife,
    I read the bible through and through on my way to Timbukto ... "

    The poem makes a great impression, and the priest smells a sweet victory.
    But then comes the shepherd, with his winning masterpiece:
    "When Tim and I to Brisbane went, we met three ladies cheap to rent.
    They were three and we were two, so I bucked one and Tim bucked Two ... "

    SCNR,
    Lars
