H,i I have just bought a new manifold for my twin port 1300, so my question is what do I do with the little pipe on the manifold, do I have to connect something to it or blank it off,
Thanks

Unless you're using a standard air filter just blank it off.

I think I have a pancake filter

As David says the one on the manifold down pipe needs blanking off as it is not used on the pancake filters.

Say I cant find my pancake what should I use instead as a good start.

Your pancake probably got eaten last Tuesday...a crepe or a waffle would do the same job...

Nice timing there 
It depends on the body clearance above the carb you can get cheap pancakes actually there is a new unused one in the shed I paid £12 from machine 7 for but you can also use a cone filter which will be better and can be fitted with or without an elbow.

Ok good feedback thanks great help,
