Possible horsepower gains

[twowheeltexan]

Just curious if anyone on the site has done a before and after dyno run on their second generation Venture or Royal Star after adding some or all of the following items to improve the performance :

1. Aftermarket slip ons.

2. K&N or other less restrictive air filter.

3. Dyna 3000 or other ignition mod.

4. Jet Kit.

 

I am sure that many people on the site have done some or all of the above and if you didn't confirm the results with a dyno run what did the seat of the pants feel indicate after the mods.

I had one done after adding BUBS and K&Ns but it was an inertia test and was done in 5th gear "OD" it showed 74.9hp in 5.04 seconds and 82.49ft*lb in 1.92 seconds but like I said this was an inertia test not a real dyno. This is not bad when you think about it's in OD from 1341 rpm to rev limiter in 5.04 seconds. I do want to put it on a true dyno one day just to see. The 98 hp YAMAHA says you have is at the crank not the rear wheel. "Seat of the pants" AWESOME!
