Drop a pulley size?
Drop a pulley size?
Ok so i am running a 3.4 right now with absolutely no KR under full load in the hottest time of day. would it be safe to drop to a 3.3 or even a 3.25 and if so is there any other parameters i should watch other than KR?

Try a 3.3 and see if you get any KR. Its good to have a tiny bit.
