Disadvantages, breakdowns and problems B1
Versions of internal combustion engines with a carburetor are difficult to set up, but most often there is already an analogue
Modifications with an injector are more reliable, but often suffer from floating speed
On specialized forums, they complain about lubricant leaks and low spark plug life
According to the manual, the timing belt changes every 60 km, however, it does not bend with a broken valve
There are no hydraulic lifters and therefore every 50 thousand km it is necessary to adjust the valves
