Default New exhaust on 81 FXWG-rejet

I lost the drag pipes on my FXWG

Here are the new pipes.

PO said intermediate jet had been changed for the drag pipes but he had no idea what the size so I pulled the carb. I found the main jet to be .068 which surprised me because the spark plugs indicated rich. The intermediate was .028.
I'm thinking the plugs may look rich because the PO didn't respect the enrichment lever.
The new pipes are "slightly" baffled, no packing

What size jets do you recommend that I start with?

295 intermediate and 70 main is a good starting point.

I guess I would rather start out running rich and not lean with the new pipes. The larger jets are on the way so I'll know next week sometime when I get the bike out for a spin.
