    Grabbed a set of rearsets off ebay last week from this joint
    just showed up today, seem pretty good for el cheapo's.. bonus is they mounting holes are the same spacing as the RZ. and they are adjustable. plus they only cost me $130 all up including shipping.














    Cheers

    sweet thanks for that mate.

    too bad I've already cut off the mounting plates for the rearsets. lol

    I'd be interested in having a look at those at some point if thats ok?

    Feel free mate, they'll be sitting round desmo's soon enough.. pretty thick ally, solid construction..
    i'll be sticking em on and mucking round with fitment and the gear selector sometime this week.

    anyone know the outside diameter of the RZ 350 upper and lower roller bearings?

    RGV standard upper is about .2-.5 of a mil too small.
    Haven't got the bottom bearing seat out yet but it looks as if the rgv bottom bearing.

    anyone know the exact bearing dimensions i'll need to swap the front end over? been searching round but it's just giving me the irrits now.

    Cheers

    You can buy them direct from yamaha. As far as I am aware, they are not a standard size that would be stocked by a bearing supplier.

    All you need it a 5mm spacer (iirc.) underneath the yamaha bearing.

    You can buy them from Norbo on the yamaha-rd forum for about 20 quid I think. They are $90 here iirc.

    make sure you fit the spacer before fitting the bearing. They are a bitch to get back off if you forget the spacer.

    Ask me how I know

    You are talking the steering head bearings? Im pretty sure years ago i bought a couple of sets from a Timken bearing supplier. Take them into a bearing supplier, CBC or somewhere like that, they will measure them up and tell you yay or nay. What are you doing here, putting an RGV front end in a RZ?

    Yep, RGV front and rear end on an RZ.
    The external face of the RGV bearing sits in the headstock with about 0.5mm play, which is obviously no good.
    If you take the inner bearing from the RGV, and pop it in the RZ shell, the RGV bearing fits halfway through.
    Which is obviously no good.
    Once we've fixed this problem, we then have to get the lower shell out of the headstock.
    Now THAT will be a fun job...
    Oh, and back on topic.... Those rearsets look pr0n. Do they come in gold?
    EDIT: Oh mai

    Desmo - everyone who does the conversion (well, practially everyone) uses the RZ tapered bearings. They only need the 5mm spacer above the bottom yoke because the rgv stem is longer than the rz stem.

    I've got the spacer made up (by nigel kimber - the guy with the yzr500 rep) floating around somewhere if you want to have it measured and a copy made.

    If you find a cheap source of those bearing the let me know! I've been trying to get bearing specs for them for a while.

    So the RGV stem is the same width as the RZ?

    yep.

    I fitted the bottom bearing to the rgv stem already. interference fit.

    Can't get the bugger off now to fit to my new bottom yoke (SP alloy yoke...oh yeah)

    have to get the liquid nitrogen out at some point

    Had to heat the rgv bearing race with an oxy to get it off originally.

    Ahhh, so we need RZ not RGV bearings! doh!
    That'll be the problem then :/
    Yeah, we took an angle grinder and cold chisel to get it off the stem, but I'm thinking nitrogen/CO2 and oxy to get the lower bearing out of the stock.

    Any good engineering/bearing shop will be able to press the old bearing off/press the new bearing on. That's how I got the aprilia head bearings done.

    The bearing we are trying to get out is the lower headstock shell, so it's a PITA.

    actually, I just remembered. It took the oxy to get the swingarm bearing races out. It took a dremel to remove the bottom race.

    Did it cost you anything Lee?
    Just that I can get it off with the liquid nitrogen for free. Just need to get around to it.
    Maybe after exams

    Just so we are on the same page, the bearing is stuck on the head stem yes?

    Troy, yes it cost me around $100 but my situation was different - the bearing was siezed onto the stem and I had to get the head stem thread fixed as when the bearing came off it took the thread with it - this is a common problem as the aprilia head stems are very soft.

    It should be next to nothing for just pressing bearings on/off.

    yep, the bearing is an interference fit on the stem, and the biggest problem is that the bottom of the bearing is completely flush with the top of the yoke, which means there is no way to get anything underneath it to press it off. Liquid nitrogen should work, just going to pour some down the centre of the stem. Bearing should just fall off.
    Unless I can get a really cheap new bearing.

    Not the case here.
    We have removed the race from the headstem, it's the lower shell that is still in the bottom of the headstock, it's a flush fit as well, so no edges to hit from the top.
    Dremel and a slide hammer I'm thinking.

    dremel works well.

    A little heat may also get it off pretty easily. IIRC I got it off before I had finished cutting it, due to the heat.

    The bearing we are trying to get out is the lower headstock shell, so it's a PITA.[/b]
    The quickest and easiest way I've found for removing the the head bearing shells (I'm assuming you're talking about the cups fitted into the frame) is to use a stick welder.
    You weld around the shell (on the face the tapers contact) and this shrinks it, it also gives you a lip to belt it out.

    Gold!
    Awesome tip!
    Could also weld a stick on there to pull on too I suppose.
