Lucky Phil Posted August 2, 2016 Report Share Posted August 2, 2016 The single biggest improvement you can make to the shift action of your V11 is to lengthen the shift lever arm and incorporate a new eye end mount hole 12mm ctr to ctr from the original upper hole. Shortens up the shift action to Japanese bike standards and gives the gearbox return spring greater leverage over the shift lever. It also makes the shift action a little bit stiffer which means you need a little more load on the lever before it shifts gear which makes for a faster cleaner shift. This is the shift selector. The area that is blued rides over the pins on the shift drum during the lever return after a shift. It usually has a rough finish and often doesn't bear across the full face of the pin and causes the shifter to hang up on return. Draw file it smooth and blue it to check for correct contact and if it isn't right dress it so it is. Do the other face on the left of photo as well of course.This arm always has a bend in it due to the way its stamped from a flat sheet. Carefully rework it so its flat and straight without any twists and polish the faces with some fine emory. The shifter mechanism stop can allow over travel of the mechanism. This one has had pads welded to the stop faces and dressed back to prevent this happening. Don't ever be tempted to adjust the large eccentric on the shifter cover with it fitted to the bike. It is a very sensitive adjustment that controls shifter travel and over travel and needs to be on the bench to set up correctly. It wont solve your shifting woes alone so leave it alone when on the bike. Note the detent roller, it often doesn't ride correctly in the detents. Remove and bend the roller arm until it locates correctly. Note the different covers, the later type on the left with the shift selector arm return limit adjustable eccentric and the older type on the right with the fixed roll pin. Set up the eccentric with about 0.030" clearance to the shift arm at its closest point in the travel. This later unit also has the extra banana shaped support plate. Guzzi sell a mod kit for the earlier bikes. A close up of the return limit eccentric adjuster on the later covers. The return spring can be installed the wrong way. Make sure when fitted the spring isn't contacting the cover, if it is remove it and install the other way. On the bench set up and ready to install. The V11 shifts like a Japanese bike now, short travel, slick shifts with or without using the clutch and no return binding. This is the mod kit which comes with new cover with eccentric adjuster, new selector wheel pins with the ability to fit the banana support link and from memory a new shift selector arm and spring and new centering spring. Note the shifter input arm and stop assembly in the lower right hand of the photo. The pin you can see under the shifter wheel with the spring arms around it is the large eccentric adjuster which controls the travel of the shift mechanism and provides the stops in both directions. As mentioned earlier adjust it on the bench only, its very sensitive and governs how far the mechanism moves the gear selector dog to engage the gears. If its a long way out you can have a situation where it moves the gear to a fully engaged position and then pulls it partially out of engagement during the shift and under engagement in the other direction.
