I had a couple of pals who bought these when they were first introduced. They were really hyped up by the press and it was awardede'bike of the year' before it had really been made available to the public. It turned out to be a bit of a nightmare with probelems from it's hyvo primary chain which wore out, taking chunks out of the crankcase. Then swarf got in the oil causing untold damage. The pistone rings also gave trouble and the middle cylinder would seize if the oil level dropped even a tiny bit. The early bikes also wore out their points at an alarming rate and needed constantly adjusting. This was cured on later models by fitting electronic ignition. The engine mounts in some cases were known to settle . As it was mounted so close to the frame, the crankcases would sometimes touch and vibrate the frame until it cracked! To top it all they sometimes had gear selector problems which would cause it to change from 4th straight into 1st! The tank was too small (17 ltrs) and the whole bike never really achieved the potentioal it could have done. Many of the problems were eventually sorted and the last of the 750's (the 750F) was probably the best of the bunch but it's 24 ltr fuel tank didn't make it so good looking. It was eventually replaced with the 850 but even that had gearbox problems.
HTH.
