Hi power, hi vibration

Strengths: 
unibloc head and cylinder, 125 same mounting as os 91 fx/and 91 4 stroke so it's possible to swap motors around. . . .
Weaknesses: 
Flexibility of carb mounting and one MUST lub the valve gear manually. I have 2 x 62, 3 x 82 and 2 x 125 and one of the 82s seized the big end. Not very economical. .
Overall: 
I like them, just remember to lub the valve gear just like a laser. I bought mine when the pound was v High so I got real value for money. . .
Ease of assembly:
