That is a little low should be around 140+ try a set of autolite plugs and i would check that cyl periodically.I've had awesome luck with autolite plugs burning clean have used thousands in bikes i've dyno tuned over the years .If you are not loosing coolant or getting it in your oil run it but i would consider rebuilding it some day.
