After fitting a pipercross foam air filter to my 1600 GT xflow's DGV is it usual to rejet the carb?

The plugs look OK but I'm due to do a track day and don't want to do any damage.

Anybody remember what the standard DGV jetting for a 1600 GT xflow should be?

Cheers
Gary

Get it on a rolling road , the only safe way to sort it out. Made a big difference when I had clockwork ignition and carb .
