My winter project is to shove a 900 ssie motor into a superbike frame. I have just started and I am trying to iron out some problems. So everyone chim in with their suggestions.

First off here is a picture with the frame and engine


Engine mounts of course line right up, but the swing mounts in the frame and the engine are off by about 1/4"



The other problem I knew was coming was the frame brace... How bad is it to move this up the frame?


Some more pics...



Let me know what you guys think!!!

you could reassemble the engine inside some 748 cases. that would fix the swingarm problem.

get all medieval on it's ass and force it. just kidding. i applaud your sense of adventure and am awed that this stuff practically bolts together. i remember helping my dad a long time ago with a kawasaki motor swap and it was like separating conjoined twins.

that or knock the bearings out and die grind the cases to get the pin thru.

the cases are the same pretty much - make sure they're 3 phase alt ones tho, just on suspiscion.

Re: My winter project (dr_apoc)

I'm doing the same thing but with a 620 engine.
What are you doing for a swingarm, you pretty much have to go with the SSSA or maybe the xx9 swingarm, but I'm not sure about the xx9 swingarm matching up with a xx6/8 frame. I'm using a SSSA from a SBK and have already die grinded the swingarm mount point I just need to do some final sanding. The frame, engine, and swingarm all line up perfectly (with a little shiming b/w the swingarm and engine mount) There are marks on the cases where they need to be cut. Check the image below. You have to remove the 4 needle bearings first (2 per side case) and their seals. I pointed out the needle bearings with the arrow. These are a bitch to get out if you don't split the cases, b/c you can't get a drift in there b/c the bearings on the other side are blocking the way and you would just push those into the center of the cases.
But if you get that first one out the second slides out pretty easy. All in all I would recommend splitting the cases, it would probably be easier and cleaner cause you could use a drift for the bearings and a mill for grinding the swingarm mount point. The cut you make on the case is not precise it b/c you will be shimming the swingarm anyway.


The bottom pic highlights in red the section that need to be cut out. A little more needs to be chopped out the alt. side, but you can clearly see the marks on the case showing where to stop cutting. The top pic points to the bitch ass needle bearings and you can see the markings a little better, w/o my mad photoshop skills covering them up.


For more info you can check my thread: http://speedzilla.zeroforum.co...36242. I will be updating it soon now that the swingarm mount is almost done and the dry clutch will be done when the gear puller gets here (hopefully).

Feel free to PM or email me at matty22c (at) msn.com. Norm is a valuable resource, he does lots of custom monster work and has done tons of SSSA conversions. That is where I got most of the info I provided above before I started working on my project.

Re: My winter project (jager)

So basically you are saying by grinding the cases down to make the swingarm fit, it will also take care of the 1/4" offset?
