oil pressure light

After a good run out the other day I parked up for approx 10mins when starting I got all the inital standard warning lights but after the motor had been runing for say 30 sec the red triange flickered on for about 3 to 5 seconds and went out. I immediately stopped the engine and the restarted and all was well no light. I rode it home and no light. Let it sit for a while then started again no problem and after another say 3 goes of starting standing/starting etc no light issue. Its never done this before.

Prior to this happening I had just rode on 35mils of fast road and redlined the motor say 7mins prioir to stopping (no red warning lights all ok). I am thinking (hoping!) that it was just one of those things and the motor was hot and the oil just drained back. level was 1/2 way when this happened. Its usually 3/4 up the level (which it was when I got home after a more steady ride!)

not sure if anyone else has ever got this issue?.

Thanks for reply's. Its an 09 model and happended after a long ride out reving quite hard then stopping & starting after about 7mins.

One change that has happended recently is that I was sold the wrong grade oil for topup 10-40 and not 15-50 same Motal semi oil/spec etc. Only put in 300ml did not follow the golden rule of checking yourself and relying on others that should know & have faith in. however I have been told that this is no problem but did start to think that that may be a factor. The motor can't be that critical and they can run on full 10-40 with no issues.
