As long as one checks the engine oil level 4 - 5 times a day (only takes what, 5 seconds) when travelling at higher speeds I find nothing wrong with it.
Of course running higher engine speeds may wear things faster, but I've flogged my 1987 85,000+ miles with the 15/43 tooth count for every mile!
I see no reason that it can't run another 115,000 miles.
Allow your doohickey to readjust the balancer chain every 5000 miles or so.
Modify at "YOUR OWN RISK"!
Still riding my 1987 KL650-A1. 85,000+ miles & counting
