An industrial drier can be used to heat the engine crankcase to facilitate inserting the bearings.

"This is not true! Ayrton Senna taught the world about running richer and I fully support it. If the blades are good quality, they will not break. While it is true that when making an engine run richer there is a greater chance of the reed valves breaking, it depends on other reasons, starting with how they were manufactured. Reed valves are made of carbon fibre and resin: the quality varies depending on the quantity of the two elements and the manufacturing process. You only need a micrometer to measure the thickness and, therefore, the durability of a reed valve. Over the years, I have had blades that lasted for a whole season and others that lasted a few minutes. It all depends on the quality of the reed valve and making an engine run richer has nothing to do with it: there’s a better chance of the reed valves breaking, but it is not the cause".
