The HIF is downdraught so no lean-off issues when hard cornering.

Downdraught? Most SUs would be characterized as side-draught. A downdraught carb would be something like a Weber DGV.

However, the HIF has the integrated float bowl below the jet which is indeed less subject to leaning out during cornering.

The HIF38 will give you an increase but if your plans are to put a big valve head (Either a cooper or 1275) then you should go for a HIF44 instead really.
Or even better than both of these get Twin HS2's modified as per Vizard.

The OP's engine is a 998 and as such will not work as efficiently with a HIF44 (44mm = 1.75" approx) as it would with a HIF38 (38mm = 1.5")
