Take care brother Paul. Don't get rid of the ramps. well not completerly anyway.

Try taking a look at the ramps with the crank fitted and you'll get an idea as to what they're actually there for. Don't go hacking away 'cos you may end up spoiling it.

Think smooth smooth smooth. Sharp corners are not good, but radii are.

Check out the mismatch between case and transfers.

Don't attempt to cut into the transfers unless you have all the right tools to get into the corners and out of sight places. You can quite easily ruin the shape and upset the flow. Honda do a reasonable job, but there's still some casting flashing that can be trimmed down.

Don't knife edge the bridge between the main and 5th transfers. A small rad here is better.
