Disadvantages of the B8444S engine

  • This is a very reliable power unit and the main disadvantage is fuel consumption.
  • The most expensive motor problem is the wear of the balance shaft bearing.
  • Riding with a humming bearing will usually cause the chain to jump and the valves to bend.
  • It is also a large and heavy engine, which reduces the life of the supports and subframe.
  • Gaskets quickly tan from overheating and leaks appear from under the valve covers.
