Unfortunately I'm my builder, so asking me isn't a great option. /s Thanks for the info on what you're running though.

Hi there, I'm currently building a 421 4 mil and I'm hoping someone can point me to a good starting point set of jets since I've never run a Keihin carb before. I'm in Utah and most riding is done around 4500-5000 ft above sea level I'll be running Keihin PWK 35mm carbs, K&N pod filters, VForce4 reeds, SLP in frame pipes, cool head with 21cc domes, and 4 degree timing advance. From the What Jets are you running sticky I found a likely seeming setup posted by Handyman that's using 155 mains with 48 pilots, I was thinking of starting a little richer and doing chops to tune it in. Any advice would be appreciated Thanks 🙂
