When starting my GL1500 from cold in the morning, I usually keep the choke on for a few minutes untill the engine temperature needle moves, and then I allow it to idle without choke untill near operating temperature. Whilst heating up I rev the engine to around 2000 revs. Normally I have never experienced any problems with this. On the last two occasions, whilst reving the bike on the side stand, I have experienced what can only be described as an intermmitant grating noise, almost likea motor impeller hitting a cowling. This only occurs occasionally, and never on the centre stand. There are no problems whilst running the bike normally.
The only thing I can think of as likely to be the cause, is possibly slackness of the cam belts, however I think I would have noticed additional problems if that were the case, and also I imagine the belts would have to be really slack.
I sometimes find that when running on choke, the rear wheel turns when revs are at around 2000 revs in neutral, untill I hold the clutch in for a few seconds. The clutch plates areobviously sticking initially. Could this possibly be the problem? ie: clutch not fully releasing when in neutral and clicking / grinding when revs are applied.
The fan motors are not running at this time.
Once again I request the infinite technical knowledge of the board. Thanks in advance.
