    wow it is a great community. I feel for Axel. Though ,if he stays in BC for a while, it makes sense to do it properly. Love to see that done.

    Hey Axel, only thing I can offer is my shop here in Portland,Oregon:lol3
    I may go up to BC in a few weeks. As you keep us posted I'll see if I can meet you there. I could hold the lamp when you perform surgery !!

    on a nother topic: My question is still outthere fior RD07a owners: both of your low beams work together ( mine does not : RD07). I'd like to know if you have H4 for high beam. If your high beams are very effective I would be looking for a used set of lightd from an RD 07A to do the swap

    Oh, and still looking for a thin , OVAL exhaust pipe for my RD07, got one for sale?

    I would weld on the sprocket. Do that one or two times and your back in good old Germany:D

    If that doesn't solve the problem you can still change the countershaft. All you loose is the money for a new sprocket. Not much compared to the effort of a new countershaft.

    If it works you can build up your engine back in your own garage.

    Good luck and have a nice trip around the world!

    Greetings from the south of Germany.

    I have large diameter Two Brothers headers with a Two Brothers C5 canister, which is probably at least one inch narrower than Leo Vince. And I still had clearance issues at swingarm. I read others had the same/worse issue with Leo Vince. Therefore I'd be careful with Leo.

    As far as mounting. It is pretty poor/weak on most of these slip-ons. Original Exhaust still beats all of them in this regard. I carry an extra mounting ring with me, becasue the mounting points tend to crack/break.

    Hi Greg!

    The were made by Two Brothers but are to my best knowledge no longer produced. Does not hurt to ask, they might be pursuaded $$$ to fabricate a few more.

    I don't know how they compare to originals because I bought the bike this way already.

    Yes, they are both H4. For me they are effective enough.

    Cheers, Andy

    been on the MRT rally this weekend. It's said to be THE long distance traveller gathering in Germany. There where 60+ ATs and some TAs...

    My buddy Shappy and his "Outback Twin". He did a 3 years 160k kms RTW trip on this bike. He rebuilt and repainted it afterwars. This bike got more mods than I can tell, e.g. 43l Touratech tanks, Wilbers shock, extended forks ...
    [​IMG]

    Inmate T.J.s Transalp and my AT. This TA got 220k km without any major probs:

    On these bikes I don't know all the riders / owners personally so just some eye candy:

    There were some TAs also (for you lurkers from the TA thread):

    Wow ya, thanks for those photos. Some very interesting bikes have been created from the AT base. As to that first tasty tan and brown bike, where are the front turn signals?

    The front turn signals are the two narrow white stripes on the dark brown ground. They are the turn signals which are on the side of BMW 3-Series cars, heated and bend a bit to fit the curv of the AT side fairing.

    Been searching everywhere here for motors. Seems like any AT thats gets totaled here either gets repaired or parted out quickly.
    Just completed a 5000 mile trip on mine. Never let me down.

    Building crate Saturday for shipping back to SF......

    So I'm posting this from Honda Trailbike Forums. Thought I'd get some input from here.


    I replaced my front disc (OEM), with a custom wave disc on my RD03 a couple months back. After replacing the disc and the pads, I started getting squealing from the front end, typical of a set of pads that needed to be replaced (even though I just replaced them.) After a week of thinking that maybe since I'm pretty much at the maximum material condition (new pads + new disc need to wear on each other a bit before running smoothly), I went down and took off the front wheel. What I found was that my freaking disc had eaten away at the caliper. There is a good 1.5mm shaved off. See pictures:

    [​IMG]
    That whole slightly lighter gray area above brake pads is the wear area. As you can see, the disc has taken off a significant amount. It should be noted that the disc itself is hardly damaged. Probably since it is much newer and is much harder than the caliper material.


    [​IMG]
    Not a great picture, but just to be thorough...

    What I was noticing, as well, was that when I'm coasting to a stop, or using the back brake only, I hear no squealing whatsoever. However, when I start to apply the front brakes, I get the noise. This makes me think that when brakes are not being applied, the disc is running through the caliper with no contact, since it has eaten away at the caliper already and there is no more material to grind against. However, my caliper must be misaligned or something, since, when I apply the brakes, the disc comes in contact with the the caliper.


    Then, I went back to my old disc and had a big WTF moment. My old disc is not planar... not flat. It looks like the actual friction surface (where brake pads contact) sits a few mm offset from the mounting hole surface. This has the effect of moving the brake pad surface a few mm away from the caliper (where my disc has been eaten away).

    [​IMG]
    Here is the OEM disc. Looks flat and normal from this angle.... but...

    [​IMG]
    There is a clearly a height difference between the inner diameter and the outer diameter. The height is relatively constant around the whole perimeter.




    So my question is, is the OEM disc meant to be that way? I can't imagine my caliper has warped it into that shape... but it looks so uniformly offset... I have had one guy tell me that these are meant to be this way, and another guy swear that RD03 front discs should be flat and it looks like mine has dished from overheating... Which one is it?

    Checking standard disk thickness in your RD03 shop manual will provide the answer.

    As far as disk to caliper clearance goes: given your wheelbearings are OK, your wheel might not be in correct position due to wrong assemly or wrong distance-bushing.

    I support checking issues like this in the kithcen.

    does the caliper float freely on its bracket?

    @Andy: that was my first thought too. But if you look closer, it's his caliper mount bracket that is in contact with the disk.

    In addition, the problem could be the result of a damaged/bent (e.g. from a crash) caliper mount braket too.

    Well the kitchen was the closest flat surface I could find.

    The caliper floats freely on its pins. The pistons are not seized. I am in the process of replacing my front wheel bearing.

    I've played with the idea that my wheel is assembled incorrectly, but I've gone by the shop manual and I've used the same bushings as were being used with the old disc, and am confident I've mounted them on the correct side.

    As of right now, I'm just trying to find out if the OEM RD03 discs are suppose to be flat or not. The wheel bearings and steering head bearings are in the process of being replaced.
