Couldn't find a 110x18 rear Roadrider, so fitted a 120 instead. Goes on without problems, looks better, and the slightly raised gearing is nice.
I noticed some time ago that Tribute Blacks in other markets had 120 rear tyres, and the owners manual states that a 120 is the correct size. Picture shows the 110 tyre, the 120 fills the rear mudguard up much better.
Also made a baffle (well, a friend did) for my Silman silencer, which avoids needing fibreglass packing.
All in all, very happy now with the bike, and just gone past 14000 miles.
The carb conversion is excellent, just need to weld up the holes in the RH toolbox to be able to use it, and Lengthen the reserve pipe on the Yamaha fuel tap, as I only get about 10-15 miles on it, which isn't enough up here.
