Hello All,

I recently bought an '05 F4 1000 S, having owned an F4 750 in the past. The new bike has a RG3 exhaust and midpipe setup installed. It looks, sounds, and runs great, but the tips are not perfectly centered to the tail section. They are aligned properly up and down and the spacing between them looks to be even, but the entire set of pipes is shifted to the right (when looking at them from behind). I have noticed this (and worse) on lots of other F4s and it always bugged me.

Is there any adjustment available within the mounting system of the pipes? I looked but nothing seemed obvious. I searched both here and through Google but none of the search terms that I used found any results. Any suggestions for getting them aligned properly?

Thanks!

Just undo all the fasteners starting from the mid-pipe all the way to the dog-bone fasteners under the seat. Re-align the lot and do up all the fasteners again, keeping a eye out for which fastener moves the pipes out of line. Then you should be able to figure out what to do to sort the problem. Also be aware that the mid-pipe brackets can also be adjusted on the frame.
Hope this helps.

I played around with it and in the end one 1/2" aluminum spacer sleeve placed over the lower bolt on the right-side subframe to exhaust bracket, and a longer bolt, did the trick. Pushes the whole assembly over just right. I tried using spacers on the upper bolt on the left side to pull it over, but that was taxing the rubber mounts too much. Pushing it worked better.

Are they off from the factory, or does heat cycling warp them? It would be really odd to me if MV would allow one of their upgrade parts, and such a visible one at that, have such an obvious design flaw.

I take it you will have removed the RG3, stuck back on the original and the original pipes look good and square?

if not? is your sub-frame okay? (just a pointer) as I had a mis aligned sub frame which made the exhausts look offset

(but then i did throw the bike down the road with a 80mph lowside)

even with sub frame problems some (not so gentle) alignment technics and time did ensure all ended well.

if you havent put your originals back on, try them,

Unfortunately I do not have the stock exhaust or midpipe as the original owner had the dealer install the RG3 setup and did not ask for the stock parts (why do people do that?). However I went through the subframe and it all appears to be straight.

since you already have spacer add more washer to the side exhaust heading to that direction, don't forget take off two metal spring, play around little much sure it align in middle of the tail, tight to bolts then put the spring back.

You have to dick around with the two dogbones that the mess hangs from to move it one way or another. Also that semi circular piece under the the mufflers that ties them together needs to be played with. I made a new one----- Oh and you can get them lined up perfectly. Both the individual spacing and centered under the tail.

Putting a spacer on the dogbone on the right side worked for me. Now they're aligned with themselves and the tail section perfectly.
