For those who tow...

Well, Noel, if you read from the top of the thread, you would see that it is about towing an FJ, and the various options available. If you choose to tow the bike from its front wheel, and allow the rear to roll, the chain should be removed so the transmission will not be harmed. This is why I'm interested in towing the opposite end of the bike.

An option is just to remove the engine and then take the transmission out ,but that is a little more time consuming i think

Is there anything in the instructions about a steering damper?  I know most sport bikes these days have them standard.  I wonder how well the geometry works with the steeper fork angle?  It should act like a trailing link being pulled in reverse and be very stable.  But I wonder if some combination of speed and bumps could cause a wobble similar to the wheels on a shopping cart (trolley)?

Very funny Rick.

Anyway, it appears my question isn't going to be answered, so I'll drop it.

Noel - my guess is the output shaft is pressure lubricated - not splash lubricated like an old style truck manual transmission.  That said, the FSM does show pressure feed to the output shaft of the transmission - but I'm not sure what gets it.  I do know the transmission that came out of the engine I had with the spun rod bearing also suffered a lubrication failure and required a bushing to be replaced.  I'd guess short distance and low speeds everything would be fine.  I'd be leery of longer distances or higher speeds - but out of ignorance rather than knowledge!  As I've gotten older I've learned to respect not knowing what I don't know a little bit more!   :drinks:

But then again, I really prefer towing in an enclosed trailer - but my formative years on that were in Florida with frequent rain showers to and from a race track.

Maybe I missed your question, Noel. I answered why the chain shoul be disconnected at least twice and provided an image of the factory's caution. I'm not sure what question you still want answered.

This was addressed in the AV rider forum link above. It was resolved with tire pressure and tight straps.

Admitted I just looked at the ADV link.

Is the one pictured in the link a prototype?  Appears it is not painted?  Also, guessing this was a DIY project initially?  Really surprised to see the pivot bolts mounted in single shear vice double.   It would only take a very simple design mod to correct that.  Also would be a good time to incorporate a replaceable bushing for those wear points too.

The website would suggest more than a DIY prototype. I'm going by the apparent stability shown in the product videos, but it seems to be very stable, especially compared to the one I currently use, as Pat's heart rate will support. A closer look at the single shear pivot bolts reveals gussets in the elbows of the bracket, which should eliminate stress concerns there. I'll know more when I get my hands on the actual product, and I can make a "seat of the pants" judgement about viability for the Rubenesque FJ.

I don't know what's going on but this is a screen shot of your post.....



...you reference it but then nothing.


Anyway, I won't dwell on this, the forum has enjoyed a period of harmonious interaction between members recently and I have no wish to spoil that.

Chris nailed it. Some, but not all, motorbikes have gear boxes that are pressure fed, that is, they need oil pressure from a running motor to stay lubricated. Some even have surface mounted capillaries running inside the casing to route oil. All car gear boxes are splash feed.

I can see it too, but there have been times in the past when pictures have been mentioned in posts, but weren't there- I usually put tat down to typing errors, but maybe there's something more to it!
