March 17, 201016 yr I`m having problems finding a con rod kit or bid end for my 242 montesa. Does anyone know where I shoul try or if something from another bike will fit?
March 17, 201016 yr A CON ROD OF COTA 247 SHOULD FIT . ASK *ULTAC*UK/*AVE RENHA* .( DOES MONT PARTS ALSO ) GIVE HIM ALL SIZES , LENGTH , S/END DIA. + THICKNESS , BIG END DIA. + THICKNESS . SHOULD MATCH UP
March 17, 201016 yr Hi, You may find that a genuine 247 rod is little wider at the small end. This can be resolved by making modified small end endfloat control shims. Piston supply still seems to be a bit difficult, although we have found a couple of options. One involves moving piston ring pins, and another involves machining and replating the cylinder. If anyone has come up with a better option, please let me know! Regards Steve

Regards Steve Steve,I have fitted a steel liner,matched to a mahle 238 bultaco piston from dave renham,just had to drill two holes in the piston to match the transfer slots as per the origional piston.No problems with ring pins as they missed the ports. Cheers,Paul.
