Re: Upgraded Black Dog.....
It made it a bit quieter, just a different sound really. And yes, more power I think... it did seem to pull stronger on hills, why I don't know. BUT at the same time I changed plug and the plug cap and wire too so it might have been a combination of all four. Still I think it was well worth the money.
