I had V & H True Duals on a '98 Heritage (shop bike) and burnt the back of my left thigh almost daily. I got a good price for them when I sold them at a swap meet.

 

Check out this dyno sheet with a 2-into-1 Thunder Header and MGS True Duals. Power curve is better in our opinion with the True Duals. What do you think?

 

Anyone tried the MGS True Dual system?

 

Impossible. Unless you are now running in a higher gear than you were before. Simply impossible.

 

Glad someone else caught that, But I think I figured it out. He wasn't getting into 6th gear before. Either that or the fuel pak tweeked his speedo. Don't matter whether you're 1 up, 2 up or 4 up, RPM vs speed is straight simple math and it can't change without changing gears, pulleys or tire size.

 

The gearing is a solid mechanical lock-up(assuming no clutch slip), RPM will not change at a given mph no matter if its 60 hp or 2000 hp.

What will change with more power is the position of the throttle, a engine with more power will take less throttle to do the same speed. RPM will continue to be the same for a given mph no matter how much power you have.

 

How did I miss this thread? Maybe after he changed pipes, he was going in the same direction as the wind and therefore needed less RPMs to go the same speed.

 

did the same with great results
