Portcitygps I'm in the middle of doing this swap as we speak. The rear exhaust tube has to be removed in order to pull the sp1 swingarm off. But my concern at this point is that I have all original SP2 Hardware sleeve everything and when I put it all together static just on the swingarm before installation I have a fat eighth inch of play from side to side. My question is will the frame and swingarm compress enough to take out that play and if so which side is the sleeve supposed to go in on?

Portcitygps Anybody still monitoring this post?

Waldo I did some measuring and the old SP1 parts are 36mm. The parts list says the new are supposed to be 36mm. I'm not sure what came with the swingarm I bought. They measure at 28mm.

New parts on order.

Waldo I am finally getting around to installing a 03 swingarm in a 00 frame. I am a little confused at this point. Old swingarm and related parts have been removed. I went to put the new swingarm in but the below parts are too small to screw into the frame. What am I missing?

Part Number: 52108-MCF-D30
Description: BOLT, R. for 2002 Honda RVT1000R

Yup, that's the definitive answer. Thanks for clarifying everyone. I will tweak the document and repost.

Thanks everyone! Ride safe!

Update as of 03.21.10: docs have been edited, and a white background version added.

This would be the reason for the spacer in the back of the motor. The reason others have done this and it has worked was they had all the SP2 hardware. The SP2 hardware screws into the frame. The SP2 hardware then centers and supports the smaller pivot bolt so the swingarm does not move around. If you do not have the spacer in the back of the motor, the motor could still move around.

That is my understanding for the needed spacer in the back of the motor. I would bet that the collars in the swingarm are also smaller. They may not press against the motor very well without the spacer.

thewax Right im installing an SP2 engine into a SP1.

The SP2 engine will not go in the SP1 Frame & Swingarm without taking the spacer out of the rear of the engine.

So if you were doing the SP2 swingarm swap into a SP1 i would say youd have to put this spacer into youre engine as the hole in it is the same size as the SP2 swingarm bolt, and this is what the rear of the engine is mounted on

Hope this helps

Waldo I hope so. I have all the hardware and I was planning on doing this swap before the 17 of April (APEX track day). With the info I was given on Rouge, I had some bushings built (still need to pick them up). There was nothing said about the shoulder on the side. I will have to check the pivot bolt diameter to see if it is the same as the bushings. I will try to do this Monday.

3stripes I think where there might be a differences is that. The sp1 with sp2 swingers had all of the sp2 hardware(motor mount bolt/nut/stock parts) and there for does not need the sleeve?

Where the sleeve come in is when the sp1 with sp2 swingarm but all the original sp1 motor mount.

Does that sound correct/make sense?

bensexcessbikes Have I done the SP1 to SP2 swingarm swap? No, but I have parted out two SP1s with SP2 swingarms and neither had the special sleeves. I only rode one of them and it seemed fine. Well, I should qualify this a little more. I have swapped the SP2 swingarm onto the SP1 frame with no need for sleeves (it didn't wobble or do anything odd).

Some of you may remember my SP1 resurrection thread from a few years ago.

https://www.speedzilla.com/forums/rc5...on-thread.html

This particular bike had an SP2 swingarm on it when I got it, and no sleeves...The bike was rock solid, well done but cosmetically a little beat up.

Is there per chance someone out there that wants to do the swingarm swap who may be able to disable their bike for a while? First, try it w/o the sleeves and then try it with (if needed)?

3stripes thank Ben and everyone else that added to this discussion.

Question Ben,

Have you done the sp2 to sp1 mod your style meaning NO SLEEVE?? If not..then stop here.

If so, then how did it work/perform?

I've actually sold a sleeve someone else sold me because I wanted to do this mod..it end up being sold for $30 to another member..don't remember who it was.

vanessa you know Thorsten's will be correct !

2 identical sleeves 20mm ID, 25mm OD for 85mm with 3mm thick x 31mm OD flange at one end (88mm total sleeve length)

These are inserted into each side of the engine, but the flange on the right now means there is not enough space to fit the swing-arm, so replace the steel spacer beside the right hand swing-arm bearing, (originally 23mm long) with a 20mm version (aluminium should be fine, it only runs in a seal, not the bearing), which ensures the overall length is now as original.

i've pinched this from another post. having done the swing arm swap myself, using the spacer dimensions waldo has posted above, the bike wallows in fast sweepers and sends the handlebars into a predictable steady shake. this is due to the lack of contact area.

the above is the correct way to do this mod, hope this helps Ben.
So is it better to just buy Durbin kit? Does his have this same mod?

Waldo Found this on one of the other sites

Any average machine shop can make an insert for the engine case that can be inserted through the frame without removing the engine. It can be one piece or two, Deminsions are as follows:
OD = .98 [24.90 mm]
ID = .78 [19.90 mm]
Length = 6.875 [175 mm]

bensexcessbikes Nice, thanks!

So these are not the stock spacers?

Swingarm conversion sleeves ,CNC-Machined from T7075 Aluminum


...which you need for 02 swingarm-rebuilt for 00/01 Models 89 $
Or to lighten your existing sleeve,which is made from steel.
2 Versions available:

- I : If you have dissembled your Engine ,then it's easy just to mount the sleeve as it is
-II : if your Engine is mounted,I can machine the sleeve slightly (does not hurt the Function),
that your able to press the sleeve into crankcase without removing the Engine
Parts & Prices

This is what i came up with.

bensexcessbikes Hmmm...news to me, but thanks Vince & Dave.

Anyone have info on the spacers?
