Woodchips Posted April 6, 2015 Share Posted April 6, 2015 Thread size RT1100 Anyone know the thread size offhand for the right hand mirror mount next to the brake resivour, going to install a Ram ball mount there and need to buy a bolt. Ron Link to comment
Clive Liddell Posted April 7, 2015 Share Posted April 7, 2015 Hi Ron, Unfortunately, you may have trouble finding a bolt with the correct Left Hand thread. The correct bolt is available from BMW of course - take your cheque book with you! :>) The reason for LH thread is in case you bump the mirror it tends to swing loose... Link to comment
DavidMantle Posted April 7, 2015 Share Posted April 7, 2015 I have a `96 R1100RT and the right hand mount on mine has NO thread . Just a plain hole. Link to comment
lkchris Posted April 7, 2015 Share Posted April 7, 2015 I have a `96 R1100RT and the right hand mount on mine has NO thread . Just a plain hole. OP can verify this by looking for the nut on the mirror shaft. Link to comment
Woodchips Posted April 7, 2015 Author Share Posted April 7, 2015 Thanks guys. I have a lot of metric bolts in my collection and was beginning to think that the threads were stripped and that was why I could not start one. I never gave a thought to left hand thread,(must have been another "seniors moment"). I'm not sure if I will tap a new thread or leave it alone and locate the Ram ball elsewhere. Ron Link to comment
szurszewski Posted April 8, 2015 Share Posted April 8, 2015 The internet shows you have a few Fastenals aroudn town ad well as shops called Calgary Fasteners and The Bolt Supply house - might want to ride the bike over to one of them and see if you can find something that fits. Fastenal at least usually has a range of left hand thread bolts - those others might as well. Link to comment
Woodchips Posted April 8, 2015 Author Share Posted April 8, 2015 I was out today at a local specialty fastener shop picking up a replacement handlebar bolt I lost in the shop last night. Now after learning about the left hand thread in the mirror hole, I will have to suite up again tomorrow and head all the way back to the shop and if they don't have one I'll have to ride all over the city checking the other shops for one, and its supposed to be warm out too. :-)) Link to comment
nrp Posted April 8, 2015 Share Posted April 8, 2015 At least you are in a Metric country but I'll bet you won't find a LH nut. I had a helluva time finding a RH 10 mm metric nut for my R90/6 per: http://forums.bmwmoa.org/showthread.php?77368-Metric-Fastener-Rant Link to comment
Selden Posted April 8, 2015 Share Posted April 8, 2015 Out of curiosity, why the RIGHT side? Using a GPS requires taking your hand off the grip, so it's normally center or left of center. If you can't find the appropriate LH thread, you could 1) use a smaller bolt, with a nut (preferably with a nylon locking insert) under or you could tap and cut new RH threads in a larger size.

AndyS Posted April 9, 2015 Share Posted April 9, 2015 you could 1) use a smaller bolt, with a nut (preferably with a nylon locking insert) under or you could tap and cut new RH threads in a larger size. This seems the best way to go anyway. It doesn't require much strength, so an M6 stub through that hole would be more than adequate and if you want to keep it looking professional, you could just insert an appropriate bush in the housing hole.

Woodchips Posted April 10, 2015 Author Share Posted April 10, 2015 Hi Selden I have the GPS on the left hand side using the RAM system, the right side was going to be for a planned purchase of a Spot tracker. Besides, the search is a great excuse for riding. :-) Ron Link to comment
