Don't tell PETA, but I thought I'd give this horse a few more kicks....
After disconnecting the TPS and getting a few good miles in, I have this to report:
The bike runs smoother. The throttle is more responsive. My gas mileage hasn't changed - still average about 45 per. And, the most impressive result, when I hit the limiter, it no longer dies for several seconds - it just burbles a bit to let me know it's time to shift or back off.
The only downside so far - I work nights - leaving at midnight - and I used to have to pull the choke out 1/4 to 1/2 to start the bike. Now (and it's been in the high 40's low 50's) I have to pull the choke out all the way or it doesn't want to start. Once started, I push the choke in about 1/2 and give it a minute or two, and it runs fine.
For those who hyper-analyze these things:
03 America 790cc.
Thunderbike silencers.
45 pilots, 130 mains. Slides drilled to 7/32.
Stock airbox with snorkels removed, K&N filter, with screened bellmouth fitted.
Vacuum balancer hose fitted between intake manifolds.
Knurled thumbscrew pilot screws set at 3 1/2 turns.
Nology coils and high performance wires.
89 octane gasoline.
It seems to work well for me.
