micky Posted July 28, 2007 Report Share Posted July 28, 2007 I have just bought a 1977 Ty 125 off Swiss e-bay (Ricardo). It is very tidy but totally gutless! Are there any quick fixes that can be done at home to liberate a few extra horses? I wonder if it was maybe restricted for use as a learner bike?

jer Posted July 29, 2007 Report Share Posted July 29, 2007 I used to have one, they never did have much power. The barrell and piston from a TY175 fit sraight onto it, everything else is the same, except I think for the tailpipe which was much bigger.
