Chain what kind???

Drives is Ok, It does stretch but it's has a fair price. I just put EK 420 cycle chain on the red scrambler racer and although it has a small amount of hours lugging my big butt around it has not required any adjustment. It was not cheap. If you want to learn something about chain and sprockets or if you want to purchase some titanium chain check out Sidewinder chain. Motorcycle Chains | Motorcycle Chain and ATV Chain | Worlds Finest
You could probably lighten up your racers considerably by going to titanium sprockets and chain.

When buying a cheap chain just make sure you dont get stuck with split rollers. Rollers are there to stop hp robbing friction between the chain and sprocket. a split roller is curled around into a circle but not welded together and they can break under high load situations or just wear till they break. Then you will see the pieces in the bottom of your tub.

Just checked ag supply $ 286.56 for a 50 foot roll of american chain # 50 dont kow what brand u can check.

I get either Diamond or US Tsubaki from Motion Industries and I think the last roll I got was just over $400 (50ft). I've had about the same luck with both brands- don't think you can go wrong either way. I got foolish one time and bought some no-name Chinese chain from Tractor Supply and the results were less than optimum.
