Topic: 350F tensioner

[steve]

I just purchased a 1973 CB350F with an issue.  Someone twisted off the cam chain tensioner bolt (the locknut one) and then proceeded to partially drill it out.  I am looking for any recommendations.  Has anyone had this happen before?  Thanks for your help in advance.

Is it same as 400(350 never came to uk) if so there is a manufacturer in uk who makes a stainless insert to replace the case thread and comes with stainless bolt and locknut, i will try and find the link on the uk site

Thanks.  Any clue on drilling out the old one instructions?

If you click on the kit on the web site it tells you what size to drill and tap, 10mm i think. Personaly. I would want to split the cases as its in a very awkward place but if you can get straight on it drilling carefully with well greased drills and greasing the tap should keep most of the swarf out of the cases and being alloy small bits should not hurt
