Hi all, I have a couple of questions concerning the chain and rear brake of a 96 NH 750. When I visited Graham last week we adjusted the chain (among other things), since it was quite loose. Once I got back home I start hearing some kind of clocking noise when I start from a stop. It appears to be related to the chain somehow. It is difficult to describe, but once the bike start moving I can hear some "crank, crank, crank" few times and then goes away when I increase the speed. I cannot tell if still makes that sound when moving faster. Last night I though maybe the chain need to be readjusted or something (although I never experienced this when the chain was too loose). This time I tensioned the chain a bit more, leaving just a little slack (perhaps was even too tight). The noise then got worse, I could hear the same thing just at the instant that the wells start moving. Then I loose the chain again, and came back to the original point where I was, with the same noise. Since I moved the wheel back and forth, I had to adjust the rear brake as well. The I noticed that it was getting stuck after applying it. I mean, I push the leaver, it comes back, but the brake is still stuck. I had to move it with my hand to disengage. I went to the Common Service Manual to check what I was doing wrong, and then I saw in the section about chain adjustment "After adjustment, retighten the axle nut to the specified torque" (pag 46). I remember I had tighten the nut really hard. So I loose it up a little bit, and then voila!, the brake is working fine again. I drove it today, and actually the noise had been reduced as well, although I still hear an small crank when starting from stop.
Questions: 1) Does any of this makes sense? 2) Could the noise be related to the torque applied on the axle nut instead of the chain tension? 3) How do I know what is the right torque for this bike? 4) Is there a tool that indicates which torque is being applied to the nut? 5) How much slack should the chain have? is there any consistent way to measure it? Thanks in advance, Javier. -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group. To post to this group, send email to [email protected].
