Hey Guys,

Last night I drove a Banshee with Dyno Ports on it (two pipes, two silencers) and I have a couple of questions.

I took off and 1-4 gear seemed pretty good, but then I hit 5th or 6th (one of the two) and the thing just died out. If I was accelerating at all I would be suprised.

Anyway, I got it back to it's owner and I asked him what was up with that and he said that the dyno ports are for low end power (which I knew anyway), and that they die out in the top gears because he put a 15 tooth front sprocket on it because it was putting too much tourqe on the 14.

He asked me if I saw a difference in low end, but since my Banshee wasn't there I couldn't tell.

Needless to say they didn't impress me much. Are these the typical results from the pipes or is this guy BS'ing me?

Just wondering.

What are dyno ports? Pipes?
Even if its a low end mod, it should still pull the top gears if its strong in 1st-4th...I think.

 

Yes, Dyno Port pipes.

I am wondering if it is in fact the pipes causing it like he said, or if he messed with something else.

A mutual friend of ours is buying a Banshee from him and it needs a rebuild. The guy that owns it also mentioned that he will port it as well. I wonder if he had "self-ported" the one that rode and messed something up. Is that possible with the symptoms that I mentioned?

It is just over geared. Any motor will fall on its face in high gears if not geared right.
