Only real issue is replacing the fuel pump and it needs a Power Commander to get the fuelling right.
The previous Pegaso was also built by Aprilia, but used a Rotax motor as mentioned by others. This was 5 valve, single plug, compared to the four valve, two plug in the BMW Funduro, which was built by Aprilia for BMW (which I had previously).
The current BMW G650G motor is similar to the Rotax motor, but built in China for BMW.
Funduro motors do huge miles - probably more than any 650 single. Main issues with the Funduro, which probably also apply to the earlier Pegaso:
- water pump will need replacement (poor design: shaft runs in the seals rather than a proper bearing) - not difficult nor expensive.
- electrics are not great: basically the wiring is thin. To cut a long story short, this results in the loss of voltage regulator rectifiers and the battery. Replce the RegRec with a recent BMW unit.
- steering head bearings.
- if the bike has been ridden in water, the wheel and suspension bearings will need to be replaced.
Later model Rotax-engined Pegasos had fuel injection - I'd prefer the carbed version.
Cheers
