woodbutcher Posted March 17, 2010 Report Share Posted March 17, 2010 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 Quote Link to comment Share on other sites More sharing options...
lulabel Posted March 17, 2010 Report Share Posted March 17, 2010 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 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. Quote Link to comment Share on other sites More sharing options...
