I swapped out my banjo bolts for the 4 hole design. I also get the post above that it can be a nightmare if it isn't done correctly. That's true. Having done the job I think the risk is minimal so long as the bolts are carefully placed to start with using a gentle hand to avoid a cross-thread.

The Honda TSB on this matter reads (on the old design): 'the lubrication and cooling of pistons may be insufficient'. This is likely a scenario under extreme conditions though.

Most S2k's get on fine using the original bolts but for my money I upgraded because I figured the additional lubrication and associated benefits can only be a good thing.
