Looking for recommendations for someone to fit inserts in Melbourne- East or Peninsula, but will go anywhere. The horror stories associated with poorly fitted seats popping out have spooked me somewhat, so I definitely want someone that will shrink them in with the correct interference etc.
Also - I got some from Minispares for a look and the internal diameter is about 1mm smaller than the existing seat. I assume you grind it out after fitting to suit the valve being used, but how far can you go? I was going to use 30mm MED valves
