Removing the lid is pretty extreme, and you'll probably bugger the mid range fuelling. A better bet is to make the intake holes bigger - I sawed off the two small holes and made it into one large one.
Others drill several large holes in the top and sides of the lid.
You can also take a blade to the insides and remove the web that splits the box in two - effectively doubling the size of the box.
Most extreme is to remove it altogether, but this is not ideal for road use as the motor will be very peaky. _________________ MC21SP Plaything

i cut the 2 intake holes out and put some mesh over the gap took the filter out and it buggerd the mid range up comptetely, but it was olton park and it was 1 degree above zero so i think i was expecting too much, what jetting would any one recomend for :-
std mc18 r5
wire splice
mod air box (as above but with webs cut out)
tyga gp pipes
tyga reed blocks
carbon reeds _________________ "cant you see the no smoking sign, this is a public space" rrrrrrriiiiinnnnngggggg ddddddiiiiinnnnnnggggggg 2 stroke till i die
No-one really likes to put jetting figures, as they vary so wildly.
When I was racing mine, I had no filter, TYGA pipes, reeds and stuffers, HRC jet kit and ignition unit, and was running between 180 and 200 depending on the weather... _________________ MC21SP Plaything
