<p class="MsoNormal">I’ll be removing my carbs soon in order to achieve clearance for raising (the front of) the engine. (Harmonic balancer installation).</p>
<p class="MsoNormal">So, it struck me that I may give my 3 HD6s another go. Swap them with the current setup.</p>
<p class="MsoNormal">Thinking it through and looking at the big box of bits, I recalled what a pain it is to get the nuts and two washers onto the bolts that hold on the air filters. I have French manufactured K&N lookalikes. The bolt starts inside the filter, goes through the carb and gets two washers and a nut. Very awkward to deal with those nuts and washers. PITA.</p>
<p class="MsoNormal">I thought that I might put in helicoils then I thought “Why not tap the holes?”</p>
<p class="MsoNormal">The holes on my HD6s are 11/32” or 8.8mm.</p>
<p class="MsoNormal">I am no engineer but it seems to me, from looking at tables on Google, that I could use a 25/64” drill bit and tap them out to 7/16”. I have both the drill and the tap but would like some expertise applied to the issue before I start drilling.</p>
<p class="MsoNormal">Any input would be much appreciated.</p>
<p class="MsoNormal">Thanks,</p>
<p class="MsoNormal">Simon</p>
