Has anyone any idea if there is another model of Yamaha clutch that can be adapted to fit the TY 175, mine has wear notches and am struggling to get a replacement in good condition, bought one off flea bay and it was worse than exisiting clutch (advertised as in great ?? condition) I know that the gear can be removed and rivetted to a new basket but dont know if anyone has found aything that fits or have had succes with somehow repairing wear notches on exisiting parts.

also if anyone knows where I can get some frame mods done local to Leeds (I want to steepen steering head angle but not that good with small gauge welding and not really got the right gear, I am fitting leading axle forks to retain rake/trail somewhere near)

There's no reason why you can't just file out the notches. I have done it a couple of times on bikes and had no adverse problems.
