CBF1000 - Drilling a drain hole in link pipe

[NJD]

Hi,

I have a CBF1000 with an aftermarket exhaust (OEM header pipes > aftermarket link pipes > aftermarket exhaust). Aftermarket link pipe has no drain hole and would like to drill one to prevent the amount of condensation / white smoke build up upon start ups and to prevent rusting as the weather continues to decline.

Have small drill bit, drill and OEM pipes (if anything goes wrong).

Am aware:

> Note position of OEM drain hole and ensure is done is as close to the original position as possible.

> Should only be a very small hole (a few mm wide).

Anything else to be aware of/advice to give?

Simple as propping the bike on a stand (more room underneath to drill) and get to work?

Link pipe image clicky.

Only ever seen drain holes in cans, would your proposed hole be directly inline with the back tyre?

It’ll backfire like buggery.

My YZF750 backfires if the link pipe to the silencer is slightly loose or there’s a slight air leak at the engine side joint.
