Kevin,
I seized it, once again!!! We're pretty sure we won't have to replace the cylinder again. I ripped the side of my radiator apart, but there was still antifreeze in the radiator, so that wasn't the problem. I did order a new radiator and top end kit, and just got it in. My dad and I are really confused as to what could be causing the repeat seizes. The next thing we're going to check is the water pump. Do you have any ideas as to what might be causing this?
Also, I'm hoping to be gettin' that third lap and chasing the season championship, just so long as I can get my top end problem fixed, so do you think the oversized tank would be a good idea. Now that I'm working with Kyle, the money won't be too big of a problem.
