Bike is 08 YZ450. My radiator level usually stays just above the core. But, the weather is starting to warm up over here and I find the level going just under the core now after every ride.
Im using the standard 50/50 anti freeze mix.
I want to try a 1.3 bar pressure cap and see how things go. My question is, is this fairly safe to use and wont harm the engine with the added pressure?

As long as the hoses, etc., are in good condition, it shouldn't be a problem. You should, if you do a lot of low speed trail riding, consider a coolant recovery bottle. Search around, there have been several posts on home-mades.
