Subject: Thanks for your help - Strange rattling noise from the engine




Guys thanks for your help.

Kirk asked me to specify the following, very stupid of me not to have done
already:
>>Any loss of power during the event?
Yes, it feels KIND OF like when you reach the top of the rpm and the "black
box" stops the ignition for half a second...
When it happens, it sounds like it can't pass the 6-7000 rpm point, it
feels "confused", the rev counter needle moves madly between 5500 and 7000.

>>What about immediate decelaration?
If I deccelarate the symptoms do stop. Below 5500rpm is fine.
>>Does the noise subside?
Yes, the noise does subside if I let the throttle. And the rest of the
symptoms as well as I said above.

Again, I cannot cause the problem at will. This morning for example, it was
fine. Last night though, it did it again. I ve tried putting her on the
center stand and try to simulate it. Nothing happens. Also nothing happens
in neutral.

Another thing is that my gearbox lever is quite tough, usually having
difficulties to find neutral when stopped. If I try to find neutral while
revving above 3-4000 then it is fine, but it is very difficult when not
moving and revs are low (revs 1300).

Heeelp! I am planning a trip from UK to Greece in the next 2-3 weeks!!!!

Thanks again guys
George
