Drak's Ducati dry clutch pushrod spacer mod' allows selecting neutral with the motor running!

If you ride an older Ducati and are unable to select neutral when the motor is running, this mod' is for you. It seems to be an extremely common issue, especially when using an after market slave cylinder like an Oberon, whether you have a Cagiva Elefant 900 like the one I did this mod' on yesterday, or a Ducati Monster like the m900s that I had until a couple of weeks ago, or a 900ss or a Paso... people seem to just put up with not being able to get neutral and call it 'character'. Well I refused to accept it and spent a couple of hours trying to figure out what the issue was and how to address it. Assuming you have ruled out other possibilities like the master cylinder not holding pressure, worn out clutch plates or air bubbles in the system, then pushrod length could be your issue. The travel of the slave cylinder piston is quite small, and the 'lighter action' after market slaves like the Oberon have even less piston travel. Such slave cylinders as the Oberon, reduce the effort required at the hand lever by altering the ratio of piston size between the master and slave, by increasing the piston diameter in the slave and therefore reducing piston travel in the slave cylinder compared to a smaller piston, thereby reducing pushrod travel between engagement and disengagement, making pushrod length even more critical. The slave cylinder needs to be able to work on a variety of motors, and not all of them will have pushrods of the same length or clutch plate stacks of the same depth and also the clutch plate stack depth will vary from when new friction plates are fitted to when they have some wear but are still working. This means that with a stack of new plates and a short pushrod much of the slave's piston travel will be taken up just reaching the pushrod, leaving very little travel to push the pushrod far enough to disengage the plates enough to allow neutral to be selected. So a spacer is needed to take up the gap but if the spacer is too long then the pressure plate will be held away from the stack even when the clutch is released and the clutch with just slip and you won't have drive. Oberon includes a 10mm spacer with their slave but I found that to be too long, and using it meant the pressure plate being held too far from the other plates even when the clutch lever was released and so there was no drive, just slip. The answer is to 'tune' the length of the spacer to your precise set up and find the sweet spot between enough disengagement for selecting neutral but not so much that you loose drive. I experimented with odds and ends that would fit, from a 3mm thick m4 nut, to a 6mm ball bearing to the ball bearing plus one spring washer to the ball bearing plus 2 spring washers, but that was because this job was 'spur of the moment' and i was too impatient to order and wait for a pack of washers that would fit. If you want to try tuning your clutch like this, I suggest you order a set of washers with 7mm or 7.5mm outside diameter and then you will quickly and easily find the height that works.
