wow ToMany, you have a lot of DATA to share I love it, and I should have thought about the wrap around the gear test, that's basically how I test my draive chains, do you know which one of those DID chains on the chart is for an xs 650, I assume all of them but if you purchased on online do you know what one you would get, if its the first the 19 dollar one is actually stronger,....
never mind that question about the chart, just purchased a DID FTS.S I paid 31.00 and 6.00 shipping from Germany not to bad I think, I did notice it doesn't have a FTSS on that chart, but the other FTS DHA and the FTS1 both have a tensile strength of 910 kgf,... I don't know what the strength difference is between 850 and 920 really is, the did does NOT have the peanut side plates..... TWO things come to mind here that may apply to this build, and I maybe going way overboard in my thought process, but here we go lol
1 I MIGHT use stronger valve springs, since I have two sets of them here in me parts bucket, and would stronger springs put more LOAD on the cam chain?? it does in my mind, chime in with yals opinion,
2 the peanut style side plates seem like they would make the chain much lighter and again in my "MIND DYNO"
wouldn't that reduce spinning weight in the engine and give some added ability to rev faster??? even if it was minuscule
