Hi Guys, Iron 883 owner from Scotland (living in Spain though). Hello to you all Had a quick search about for this answer but to no avail so hope you can help. I am changing the silencers on the bike from stock and was wondering if the bolts holding the silencer to the bike are metric or imperial sizes? I had a quick go with a metric (around 13mm if I remember right) but it seemed as it was going to slip. Didn't want to round the bolt so thought I would ask the question.

Thanks in advance, and hope you all are all having a good Friday

 

Should have mentioned I did look at the poor mans guide above and the link to tool sizes does not work

 

Should be SAE (imperial). There are a few bolts that are metric on a HD, but not many.

 

Thanks
