25DC with expansion chambers seen in West Yorkshire

[John Wakefield]

This 25DC reg No YBE413 was seen at The Oil Can Cafe bikers meet at Hepworth near Holmfirth in May this year. Has been fitted with expansion chambers with long stingers. Also looks to have a Mikuni carb in place of the Villiers S25.
Is it your bike, if so how does it perform? Has any tuning been done to engine?

Quite so Mike, I wonder if it is actually a 325 (3T) engine there looks to be a 32DC badge on the right hand side of toolbox, but according to DVLA its a 250.
