Hi....

I have checked the valve clearence and chanced a few so the was set at en middle value.... in=0.16 and ex=0.22 mm. Now the there is more valve noise than before.... and it seems to be more after the engine are varm....

Should it be so, that when keeping the clearance in the middel all is ok and no noise, and noburned valves because of to less clearance...

I follow the maintance book from Haynes... ohh... and the CBR is a '93 version...

Sincerely

Erling
