Hello 
I wonder if any of the good and the wise have any ideas? 
Towards the end of a trial last weekend the bike (92 Pinky) started to tickover erraticaly, almost as if it had an air leak.  I have checked the thing over and apart from a dry foam air filter (now oiled) all looks well. Any thoughts gratefully received! 
As an afterthough, anybody know what I can stick the saddle back on with? 
Thanks, Mike
