MPfive Posted February 19, 2011 Author Report Share Posted February 19, 2011 Right,that answers that one.So I'd need to get m6 helicoils then? Quote Link to comment Share on other sites More sharing options...
MPfive Posted February 20, 2011 Author Report Share Posted February 20, 2011 I re-tapped it 6mm today and used an m6 bolt.Now im worried about stripping the thread again.Can I still insert a 6mm helicoil in the frame or is it too late?

ForrestDump Posted February 22, 2011 Report Share Posted February 22, 2011 Ok, this may come as bad news to you if you've drilled a hole for an M6 Helicoil already, but, I was talking to a friend about this the other day as some threads in my mounts are starting to strip out so I also did some searching on here and on Google/YouTube for people who have done this before, long story short its a M5 Helicoil kit that is needed for 4 bolt mounts. Hope this has been helpful and that you sort out your mounts. Quote Link to comment Share on other sites More sharing options...
MPfive Posted February 22, 2011 Author Report Share Posted February 22, 2011 That is a great help.My only trouble now is I've already re-tapped the frame 6mm so I could go riding.I've since spoken to a mechanic friend who told me to simply by the helicoil repair for what ever size you've tapped.Which is a kind of a "no shit" answer.But better safe than sorry.I just hope the new mounts I've got coming can take a 6mm bolt.

ForrestDump Posted February 22, 2011 Report Share Posted February 22, 2011 Glad to be of some help. Most 4 bolt mounts are probably designed to fit a M5 bolt as that’s the size of the holes in the frame. However, depending on how much room there is around the slots for the bolts you could always file it out with a needle file, or carefully drill the slot out with a 6mm drill so the larger bolts fit, that should solve that problem if done well and carefully.
