How to support rear engine etc

Morning guys, I am at the point in my project where I need to take the swingarm cover/sideplates off and I am wondering what the best way to support the rear of the motor etc would be? I have the rear up on safety stands where the rod for the center stands passes already and the front will be up on stands too so I can get the lower triple out (using a stem stand atm).

A couple pics of the project so far:

What are you doing? I notice an OEM shock on the floor and one in the bike. What's up with that? (nice bedroom)

Im doing a Rc-51 front end conversion, clutch, 520 did chain conversion and possibly a vfr swingarm conversion. I picked up a adjustable 2005 shock and replaced my 2002 non adjustable unit with it last night, but may end up going aftermarket- this project is snowballing!

Oh ya, and a bunch of powdercoating, thats why I am taking the swingarm sidecovers off.

And thanks, that is my home office.

From where you are supporting the rear, you can take off the swing arm and side covers. That's exactly what I did when I powdercoated my swing arm, just put a piece of rebar in the holes where the factory center stand goes and put it on jack stands.

Should be one huge bolt (27mm if I'm not mistaken) on the swing-arm, then three more each on the side covers. Should be really easy, you are right there.

Thanks g00gl3it, so you removed both side covers when you took your swingarm off? How else is the rear of the motor supported so it doesnt try and drop or something?

The side covers don't support the engine; they bolt to the frame, which supports the engine. They are just covers is all, not a supporting member.

The swingarm bolt goes through the frame and those side covers just bolt to the outside of the frame above and below the swingarm location.

Start yanking, you'll see what I mean.

Give me a few minutes, I'm grabbing some pictures of my powdercoat job from my server at home.

I'll post a link to them; hopefully I've got one you can get a clear shot of the rear end.

Mine was torn apart like yours (not the front).

Let me know how that RC51 conversion goes; I might need your help on that some day, lol.

Well, I wasn't able to grab all the pictures but here is one that shows my bike right before we took off the swingarm.

That is Osiris in the pic.

I didn't put anything else under the bike when taking the swingarm off. I think it's supported just like you did yours, so you should be fine.

Thanks, do you have any close ups of the done powdercoated swingarm on/off the bike? Did you replace the bearings?

Here's the pictures of the powdercoating when done. And no, I didn't replace the bearings, but I did re-grease them as best I could. The swing arm doesn't see nearly the amount of movement as the axle, so I wasn't too worried about it. But when the powdercoater runs the oven, all that grease will run out so you want to clean that out really good, otherwise he might have to touch up the spots where it runs.

Then of course you want to re-grease before putting it back together.

Oh, and make sure you knock out (carefully) the seals on the bearings and remember how they go back together! You'll pull out 3 seals I believe, and two bushings. One side is smaller than the other, so make sure you mark or remember where they go.

When I had my swingarm powdercoated, the guy doing the powdercoating took my bearings out for me and told me that he wouldn't do it with the bearings in. He baked the powdercoat at 400 degrees F for 15 minutes. He didn't want the grease to run out and ruin the powdercoat or get all over his oven.
Are you doing your own powdercoat or sending it out to be done?

I dont even want to think about what the wife would do to me if I used "her" oven to bake some powdercoat

These guys are local, I am going to give them a shot:

Total Coatings


Anyone got a link to a 919 stem bearing kit? What ones do I want?

I used All Balls bearings when I did my project. Most replacement parts came from ebay and I didn't know their history so they all got new bearings - stem, wheels, swingarm. I'm sure other brands are good too. I got my bearings from ebay retailers.

I used the All Balls kit too. Just be aware that since they are tapered you can't do the pre-loading the same as the shop manual describes and All Balls doesn't provide any advice on it.

I gotta laugh.

Tell her the following, then try the good ole "see how much worse it could be?" line

The family dishwasher for cleaning parts, engine cases included AND with a varsol pre-soak

The family laundry room for a spray booth.
Plastic sheets hung on all walls.
But that did not stop some of the wet sanding fines from getting into furnace and throughout the house.
And that two part with the cyano kicker was vicious on the lungs - had to wear a real serious gas mask for that stuff, the eyes stung all the time when spraying.

The family oven for baking paint, like VHT applied to piston tops and exhaust ports, as well as the headers and the engine cases, barrels and head.

That was in 1975 when I did my CB750 build plus frame/body/engine paint job.

The little hooks for hanging stuff off the rafters are all still there, along with paint splotches on the floor. Petty Blue/Orange/White and a black engine.
Ahhhh, it brings back such pleasant memories.
And the CB is still mine and in the garage - although it has not been run since 95.

Thanks for making the post !

Actually, after reading your numerous posts, I just hope to have the same level of knowledge of motorbikes that you do some day. I guess I just need more tinker time...

More like GenG
As in Genesis .......................

The reality is I'm just lucky to have a real good memory.
As for knowledge, my base goes back to the late 60s and 70s beginning with cars and then moving into bikes.
Magazines back then were really educational, loaded with lots of tech and how to. That is the magazines that were written that way, and many were.
I faded in the 80s and stopped riding altogether in 95.
When I got my new 05 919 in 05, I realized how totally out of date I was.
I came from a simple world of carbs, and chassis was nothing more keeping spokes tight, steering head bearings and swingarm bushings good, different fork oil, a set of Koni shocks, and Dunlop K81s.
It was like being a rank beginner all over again.
Somebody told me about WristTwisters.
Lots of knowledge, lots of help.
It's been catchup ever since.
If a GenG like me can get reasonably current, anybody can.

By the way, for anyone out there that wants just ONE BOOK that covers lots and is well written and all encompassing, I challenge you to find something better than the illustrious Kevin Cameron's "Sportbike Performance Handbook 2nd Edition" ISBN 978-0-7603-3183-5. They can be had from Amazon for a song.
