Cuts in at 86deg, out again a few degrees below that.

Standard one is more than 88...it should be stamped on it but iirc it is in the 90's

Basically you're just increasing the time it takes before temperatures get critical. It's no solution to an overheating problem - for that you need a good radiator (GRS or similarwith a really efficient core) and a good fan or two to get cold air through it while sitting at the lights. A really good radiator isn't that expensive either.
