I don’t have stock tyres and the recommended Kwaki pressures for Z650 are 32/36 but I ran these same tyres on my Honda CB500f at 36/42 (recommended). Do i stay with Kwaki pressures or go with tyre recommended pressures?
im thinking running my z650 at 34/ 38, any suggestions?

You want the pressures specific to the bike in the manual (or the sticker on the bike). See the "What are the proper inflation pressures for street applications?" question here: Bridgestone’s Guide for Proper Inflation of Motorcycle Tires

Running them too low will cause the sides to wear out faster than the middle; too high and the middle wears out faster than the sides.

That said, people do make adjustments for weather, road surface, etc... but they're generally doing more with the bike than the average street rider.

I stick to the 32/36. I go higher on the rear when I want to practice drifting (i still suck at it). Shouldn't be anything wrong with 34/38, see how it feels. I should ride 38/34 considering i weigh 245lbs (111kg).

I run 25 psi front & 22 psi rear. On the OEM dunlops. I'm in the Philippines and the average temp just now is 29deg C. Road temp must be much higher 40s I suppose. No visible damage after 3000km. I weigh 85kg with my gear on.

Always remember: manufacturer recommendations are FOR the SAME tires as stock, considering a 70kg rider, considering the altitude and temperature at the manufacturer test site. So, you CANNOT always follow the same recommendations if any of those parameters is different. Tire pressure is related to road condition, HOW you ride (street/sportier) AND also PERSONAL preference 👍🏽 Use manufacturer recomendation as a starting point and then adjust for more or less, according to your favorite road feel and desired grip threshold.

Totally Agree 👍

I’ve been riding at 32/36 and am finding it handles great so I suppose stock recommendations it is.
