What's going to be the easiest way to drill my frame out for the conversion?

There was a lot of discussion on this a while back... plenty of info in the archives if you can find it

I just went crazy, drilled the frame out and got lucky. But I reckon the safest way (without high tech gear) is to tap the holes to 16mm and then ream. This will give you a better chance to keep it all aligned.-Mal

or get the correct size pivot bearing spacers so you can use the stock pivot bolt1978 GS1085.
Just remember, an opinion without 3.14 is just an onion!Comment

I just drilled the frame out to the 20mm swingarm bolt that I needed to use the Bandit swingarm.
I am a human drill press
No all kidding aside It is not hard to get it straight when it has a pilot hole already.
I wanted to use the larger bolt for the extra strengthLast edited by Guest; 06-18-2013, 05:30 PM.Comment

What do you mean tap the hole to 16mm? Like a tap and die set?Comment

Sounds like a winner for me! Thanks for all the ideas. Got tired of reading all the threads about the swap. Thanks again!Comment

BTW the 16mm hole will take the 1100E swinger pivot bolt, and that bolt is longer than the stock 750. You will need spacers or cut about 1" of new thread. The swinger is also a bit longer so you will need a couple of extra chain links, so.....this is a good time to convert to 530 chain & sprockets!
(If you do, don't forget to account for the longer swinger when calculating the number of new chain links.) I didn't

Broke my tap 3/4 of the way through but got it done. Took a new 120 Link 530 chain. Anyone doing a 1979 750 using an 83 GS1100 Swingarm the bolt does not need to be cut down shorter.
