Hi Tim, just my opinion, but I don’t like 6 springers, the buckle in some new steels is time consuming to get out, but saying that if the steel plates are PERFECT then go for it. I also think oil in the primary should be there! So apart from my Daytona (an original 6 spring ), I do run all 4 spring clutches, including the 54 RR salt bike I’m waiting to run, now next March.
I did run a belt in my 57 flash quite some time ago, and in ‘my’ opinion the lack of a cush is to ‘me’ evident. The belts used are akin to a timing belt, and so! have minimal or no flex. On my 57 flash the drive gear was an alloy unit (some time ago now), and when I looked at it after 3 years running so , and no serious miles on it, for no real reason the splines were about half the thickness, ( yes 65 fb on the nut), however my thoughts went to the fact of no cush. So from there on in, I run 4 spring (I used to use Lyfords clutches but now SRM).
My 2 cents wortz xx
Good luck mate I’m sure the bike will be fine.
I’m hoping to come across the ditch to meet up mate. Thomas
