What carb model is stock in a Roadstar 1700 (2006)

Mikuni BSR40

What jets are stock?

Mikuni 182.5 main, #35 pilot

What size screws are used in the float bowl? (these are destroyed when changing jets the first time and I plan to replace with socket head type)

Have to look that one up

Is Kuryakan jet size/numbering nomenclature the same as the stock jet manufacturer?

Yes, they both use Mikuni jets

Too bad Gram doesn't come on often as he has a lot of experience with analyzers.

The ported manifold will make some difference in that it provides a better distribution of air between the two cylinders. However, in the end the front and back will run lean/rich due to the different air flow over the cylinders (the back is more sheltered).

Your main is most likely too big. I'd start with a 172.5 and work down from there. A 170 or 167.5 seems to be where most end up with aftermarket intake and exhaust modifications.

Thanks for the info, Doc. I was thinking the main was too large and will probably change that tomorrow and run another 0x test after adjusting it to idle smoothly and test driving. I'm sure it will have a big effect. It runs great now, being so rich as has been mentioned here about Roadstars, so I'm not too worried about that while I'm riding tonight. It's a little sluggish from 1/8-1/2 throttle, but it picks up nicely from there to 70mph. That's on track for how rich it is with main jet 182.5. Can't wait to feel it's potential when it's finely tuned.

I apologize to all you northerns that can't ride right now for bringing up how beautiful the weather is here. The weather here has been fantastic, however, and I know you'd be out there if you could!

Have a good and safe night,
Steve
(Or skillet as my brother calls me. Can't wait to get up there and see him in the bluegrass state next week, but I'll be couch bound too, I'm afraid.
