Why did the Menshiviks not like the bolshiviks?

The Mensheviks and Bolsheviks split at their 1903 party conference in London from the Russian Marxist party the Social Democrats. The Mensheviks, led by Julius Martov, believed that the capitalist stage of Marxist ideology was yet to be played out. The revolution would have to wait for this stage to be completed and only then would the workers rise against the elite ruling classes. In the meantime, the Mensheviks wanted to recruits as many members as possible to assist with the revolution when it came. The Bolsheviks, led by Vladimir Lenin, had conflicting ideas about revolution. They believed that revolution in Russia was imminent and wanted to hurry it along as swiftly as possible thus skipping the capitalist stage of Marx's ideology. Furthermore, Lenin wanted Bolshevik membership to be restricted so as to create a small band of professional revolutionaries.
