G'day one and all,
The back torque limiter fitted to the Busa isn't what you would call the most effective piece of engineering. However it has it's uses, but I'm still to find them? Welding the limiter can be helpfull but a certin process need to be followed to achive the results required. First of all it must be remembered that this piece is case hardened so pre heat of the part must be done before welding is commenced or the weld will become brittle and fail. Oxy will do fine as long as you don't overheat the part, a slight browning is all that is required,then the weld process can be done. It would be best to set up a jig for welding this piece as you need to get it in the right position, and that is maxium engagement pressure.
A good mig or stick weld will be better tan a tig weld as the depth of the weld is more important than it's appearance. Once the back torque limiter is welded up a set of 5.00 mm spacers will need to be machined to adjust the static spring pressure. You will find that your clutch now responds as it should, and that is by the rider imput. If you are unable to do any of the suggested modifications please get someone who has experence at these modifications to do it for you.
I trust this helps out. If you have any further questions just post here and I'll answer as best as I can.
