qcowboy Posted November 28, 2008 Report Share Posted November 28, 2008 (edited) The TL 320 I recently purchased has no rear brake stay. The only thing that keeps the brake backing plate from rotating is the torque from the axle shaft nut. There don't appear to be any bolt holes indicating that a stay is missing, so I'm inclined to think that this is the way it was designed. Because every other bike I own has some sort of a stay to keep the backing plate stationary, the lack of such a stay on the SWM gives me concern. Is the torque on the axle shaft really the only way the backing plate stays in place? I also ask because I have some sort of drag on my rear wheel, and I wonder whether the extreme tightness of the axle shaft is causing the drag. Any thoughts? As long as you are reading this, I'd also appreciate any advice on shocks. My rear shocks bottom frequently. I suspect this results from a combination of age and wear (probably spring sag and weak gas shocks) and my weight (210 lbs.) I realize that trials bikes have mushy suspension by design, but I can't enjoy riding a bike while hearing and feeling the suspension bottom out over minor obstacles. Any suggestions on replacement shocks that would be able to take my weight, without degrading the handling? Is there a ready source for replacement shocks for a TL320?

pedronicman Posted November 28, 2008 Report Share Posted November 28, 2008 On your rear brake plate there should be a large allen headed bolt on the outside of the plate it is on the opposite side to the brake pivot cam. if it is missing you may have a hole When the correct bolt is fitted the head of it slots into an elongated hole on the inside of the swingarm inline just forward of the spindle hole see picture - Quote Link to comment Share on other sites More sharing options...
qcowboy Posted November 28, 2008 Author Report Share Posted November 28, 2008 Thanks! The allen head bolt is there, but is not installed in the slot. That seems an easy enough fix: loosen it up and reset it in the correct position. What should be the torque on the axle shaft nuts? Mine have no lock washers, and are not castelated nuts, as on most motorcycle axles I've seen. Quote Link to comment Share on other sites More sharing options...
pedronicman Posted November 28, 2008 Report Share Posted November 28, 2008 The allen bolt ony needs to be bolted back ino the brake plate, it does not need adjusting but it should have a sprung/shake proof washer fitted also. The rear spindle nuts were never castleated but a normal nut type There are no torque settings available , just tighten up to what you feel is ok ,they have flat washers as standard but it wont hurt to fit sprung ones Hope this helps Quote Link to comment Share on other sites More sharing options...
qcowboy Posted December 2, 2008 Author Report Share Posted December 2, 2008 Thabks, Pedronicman! The rear brake is mounted correctly now, and is also adjusted and working much better. Now I'm waiting for a box of parts to arrive: new airbox rubber, intake rubber, kickstart splined section, new sidecovers, clutch cable and slow-acting throttle. So do you know a source for new rear shocks? Quote Link to comment Share on other sites More sharing options...
