the weak mount is what is being tried to get rid of

 

[quote=chuckbear;907012] I'd wonder if they have the same metal.. quote]


Bingo, thats why i wouldnt do it, if the F4i's swinger was strong enough, why would they make the RR with all that re-enforcement and added weight? I'm assuming you have both? Hold one in each hand, if they are the same weight I wouldnt cut anything off, if the RR is heavier you may be alright.

 

they are the same metals...

 

IDK man, the swinger to me is like the frame, I would never cut it. But I don't have a RR one in front of me. If you think it will be fine then go for it. From those pics is does kind of look like that piece stabilizes the two arms?

 

you're also changing the geometry of the suspension completely away from the way the unit pro link works

imo if you're doing this swap...(I did it last march) you shouldn't be hacking things and re-engineering the way it functions because it's easier. if you wanted easy why not just retain the factory swinger?

if it's for show then...whatever but there you have it

 

all fine and dady I'm just questioning the integrity of the mount...

I'm debating making a mount so I cann use the stock f4i top mount (to the frame itself)..1k rr shock the 600rr swing arm...

Fine and dandy that it takes away from the originnal set up but have you seen the pics with bikes missing their bottom halves of their motors from it?

 

and I'm not doing it because it's "easier" I have all the parts needed to do it correctly I was just seeinng if had been tried before differently

 

I just looked at my mount last night. It isn't bolted to the engine but it's bolted in the place where an optional center stand would be which in turn is a mount that is bolted to the engine. If you look at this area the f4i shock is bolted to this same thing but above it. Since the unit pro link is designed to isolate the forces to just the swing arm as a contained assembly I'm thinking those with their 600rr swingarm swaps that have ripped this mount either A) Got sloppy with bolt selection and drilling B)Didn't center the swingarm thus not centering the link B)Wrecked badly. I seriously doubt it just ripped off while riding. I've got 12000 miles on hard riding and one lowside.

Just looking at the graphic you can tell by studying where the lower mount is attached and the action of the unit there is really no heavy loading going on at that joint. Nowhere close to that of a direct shock mount.

One last thing, the f4i lower mount is way higher than the center stand mount and the 1000rr shock is considerably longer than the f4i unit meaning you'd just about have to have the swingarm damn near perpendicular to the ground to bolt it to the f4i lower mounting location.

I don' t have a digital camera or I'd take some pics. Might get some with my phone. I noticed there's not a lot of good shock mount images of a RR swinger on an F4i floating around the net.

 

thanks for your input aweasel.... after reading the first post i decided im just going to use the traditional mounting spot.... reason i was looking for alternatives is "stunters" have been the ones with problems... pulling numerous stopies (i realize a motorcycle is not designed for this) they rip the mount and the block.... im just a casual rider so its not a big deal for me.... but still upsetting to see that it can happen... ide hate to be rolling down the interstate doin 70 or whatever and have my back wheels fly up and lock up under my undertail

but i really do wish we had a cross mount support off the frame like the rr's do.... would make everyone happier....

 

The f4i is the heavier bike...
