  • how noisy is your transmission?

    I need to know if it is normal to hear a whine from the trans on xs11's. I quieted mine down a bit and can hear what sounds like gear whine. one of my co-workers made the point that they are straight cut gears known to be noisy. Anybody in Harrisburg, PA? Take me for a ride, I wanna hear yer gears......

    Hey Ron,

    Yes they are square cut, and do whine a bit, but you'll want to check your MIDDLE DRIVE gear oil levels to be sure! There was a recent thread about this, the middle gear can sometimes develop a leak into the driveshaft ujoint area, so you won't necessarily see a puddle, but can eventually run low and then burn up your bearings!

    Also, have you removed the final drive from the shaft housing and greased the driveshaft splines lately!?

    If you'll go to the MEMBER's Forum, and do a search as per the sticky message, you'll find a few folks in PA, I know Randy one of our electrical gurus lives there, along with several other Xsives, but PA is a large state!

      Thanks TC, actually I swapped the mid drive with a good used one from andreas in spring. I did the shaft greasing as well and I recently (yesterday) verified the oil level in the mid drive. I have determined that the noise has to be primary or mainshaft related because the tone drops and rises with each gear change. I have a complete trans that I have undercut the gears 2 degrees, I just have to pull the motor when I get time. The delay is that I lunched a piston in my other bike and have it torn down right now and cant live on 4 wheels alone.
      What all do you suggest replacing in the starter clutch when I tear it down?

        Hey Ron,

        That's seems like a lot of work just for some "noise"! I know if bearings are going bad that it's a different story, but have you verified that they are indeed going bad?? I've not heard of anyone having them fail on them, the roller kind for the gear shafts anyways?? Many folks have commented on switching to different oils, and have reduced their engine/tranny noise as well as improved their gear shifts!

        So..you might want to try to get up with another Xsive in your area like you mentioned to have them listen to your bike, and also to hear their bike to compare the tranny whine!

        But, if you decide to go ahead and split the cases, then these parts are what are available for the starter clutch rebuild from Partsnmore.

                I'm going to have to split her open anyway due to 2nd and 4th gear damage. The lift trick usually works on second but 4th grinds 50% of the time. And this is riding vey conservatively. If you really want to wind her up you cant shift (clean) fast enough to be smooth. I'm all for keeping the gearbox in good shape, my wife likes to ride along and I'd hate for something to come apart possibly hurting her(us).

                  If splitting the cases would R&R the cam chain too.
                  Easy to do then and does not cost to much.

                    Hey Ron,

                    The act of grinding gears sounds more like you may have some bent or badly worn shift forks, shift drum. Again, the countershaft and associated gears and shift drum can be removed WITHOUT splitting the cases, just going in thru the bottom and the side covers and clutch removed!

                    You sound very knowledgeable and skilled, so I'm sure you can do it precisely. But I would think that most folks that have had the gear problems have only needed to replace the gears/shift forks on the countershaft, not the pinion gears on the primary shaft.

                      grinding into 4th

                      My tranny grinds going into 4th as well . Sometimes there seems to be a neutral between 4th and 5th - scarey

                        Hey Axel,

                        If you'll review this Trans explanation by Steve Borenstein you'll see why you/we all have a false neutral between 4th and 5th gear.....very common!

                        But grinding gears is/should not be common. What rpm are you shifting at, and are you using the clutch? Are you sure you've released/eased off the throttle a bit while attempting to shift? If you're trying to accel before you're fully engaged in gear, then you might experience some grinding when the gears finally try to mesh!

                          shifting

                          If I try to shift positively and do all the things you suggested ,I can get a shift with no grinding , but not quite every time . It takes a bit of focus . If i'm tired or distracted or different boots all contribute to the grinding . I'm shifting anywhere from 4k to 6k using the clutch .Sometimes I speed shift with everything happening very fast but lately I'm trying to take it easier . I'm suspecting swing arm bearing play or some play in the driveshaft because I hear a click when I shift this way . I'll read the article .

                            you mean to tell me that neautral between 4&5 isn't just me missing a shift
                            ALL this time I thought I needed to move the shifter more (longer throw),

                              I can do that on ony one of my bikes if the shift isn't complete. I wouldn't worry about past shifting and concentrate on sticking each gear.
