yep, I used the replacement "N" type balancer without the pin (like the OEM). You have the "SS" part which will accept a pin and good for a supercharger.
Yea, I was thinking about that too. I am wondering if the poly ones are going to give too much vibration over the oem rubber. I have a cam and it vibrates quite abit already.
I agree. "this all worked fine til I hooked up the battery tender because the battery would go dead after sitting for more than a week " doesn't sound right.
