18's front and rear - as most of the cafe conversions are. Turn-in will be much faster due to the decrease in rake and trail.

Raising the forks in the triple clamp should give you some concern. You are right at the point where a fully compressed fork will cause contact between the fender and the bottom of the lower triple clamp.

The fork lowers are tall enough that there is plenty of clearance for the stock 19" tire and fender.  (This is clearly illustrated in the picture below.)  What you need to look out for is that the fork lowers don't bottom out into the lower triple clamp.  

To do that, remove your fork springs and confirm the fork will bottom out before hitting the clamp.  

I had 2" (nearly 51mm) removed from my forks and had a few mm to spare. (also shown in the picture below.)  

You only went 33mm but that doesn't account for any differences in the top clamp thickness.  That said, you have more than 17mm more to play with so I'm guessing you are safe.

Christmas is coming and you need a fork brace
Redrill the stock fender , it helps it all blend nicely , can’t barely tell its a 18” wheel with a 19” fender
