Larin Adapter Question

[2fs2ns]

I'm going to make this up so I can use my jack...I have one question though.
You have two 7" pieces, with 2 5" pieces on top of them on the one end.  Then you have a single 7" piece on it's side right in front of them.  It looks like it's notched out to match the 5" pieces, is that the case?  It looks like it's only done on the one side though, not both.

I circled the area in question...



Granted, I'm sure it'll make sense once I get it put together and put it under the bike...it just caught my eye in the writeup.

Sorry I can't help you with the details.  I made up one of these to use with my lift (which is emphatically NOT a Larin), but it was too tall to fit under the bike.  Apparently the Larin lowers further than my el cheapo ($55) Harbor Freight unit.

So, I welded up one by cutting a drill stem in two and connecting the halves with angle iron.  Added a vertical piece of angle in the center at the back, to fit against the underside of the swing arm, and it works like a charm. 

If you want the wood unit I made, you are welcome to it, although it comes sans guarantees, of course.  (I live near Austin, between Oak Hill and Driftwood.)

Could post pictures of the metal unit, if you have cutting and welding equipment, or access to same.  Or, if you want to stop by some day and use mine, you are welcome to do so.

I can't answer because I didn't use an adapter when I had my Magna.  I just stood a short 2x4 on edge on one jack runner (the one under the rear of the bike) and let the frame tubes rest on the other.  Worked fine.  It was lots easier than the adapter I made for the Valk.  The one for the Valk took a whole ten minutes, LOL.

Hmm, I don't have a Larin either, it's a Big Red or something...maybe I'll check my clearances....

[Magnum Magna]

Just to get my big red under my Magna I have the sidestand on a concrete block (about 1.25 inches).

[2fs2ns]

Hmm, mine goes under fine, just doesn't lift up the back of the bike...

[Magnum Magna]

That make me wonder if it has been lowered.  I just changed the rear shock setting from one extreme to the other.  I will see if that raised the bike any.  I wonder how do they normally lower the 3 RD Gen Magna?

[TLRam1]

Mine goes under my cradle fine than use a 2X4 under the rear swingarm.

[2fs2ns]

How do you guys get a 2x4 under the swingarm in the process of jacking up the bike?  I just can't picture it...

[TLRam1]

You jack the bike up first than the bike acts like a seesaw with the rear tire on the ground, but not much weight on the back end. Lift the rear of the bike and prop a proper length of 2X4 under the swingarm. At this point you can lube your chain (rear wheel spins free) or remove/service your rear wheel.

Some people have measured theirs but I have several pieces and grab one that fits. I think I have heard others say it's about a 12" piece. 

[2fs2ns]

Ahh, easy enough.  Maybe I can strap the front of the bike to the jack to help take some weight as well.

Replacing the rear tire soon....

Well if you can make it to my wrench session in Feb 2nd well I have 2 of them my bike is too low to use it one is for Jesse and you can have the other!!!  I had a friend that made them for me!!!

Below is a link to a diagram, which seems to show the ends notched out.

I am somewhat of a woodworker so it was nice to use the old table saw on a bike project.  Other than that saw dust and oil just don't get together too often.  I bolted it to a Harbor Freight jack (the yellow one) and it slid under just fine.  I actually like the design alot myself.  But again, I got to make some saw dust in the process so that made it that much more enjoyable.  Good luck, dc

To  be honest I think you could build the adapter bottom like the plans show then save a piece of a 4x4 post and use that instead of the several pieces...  That part is basically a fulcrum to keep the rear from dropping.....

[2fs2ns]

I wish I could make to down for your wrench-a-thon, but unfortunately I can't

I had looked at that drawing, but thought that was a smaller piece of wood on top of the 2x4, but now I see that it's probably just notched out.  I'll probably try something like Greg menioned, build a base with a piece to support the swingarm.  My only concern now is the bolts that will go through the base into the jack.  I'm afraid when the jack folds all the way down, the bolt head or nut will prevent it from collapsing fully.  But that's something I'm just going to have to experiment with.

Thanks again for the info!
