Do the 172kits need running in like a brand new 125 kit would? I've read that many riders will fit the kit, warm up, cool down, warm up, cool down and then take it for a blast and they are good to go. Whereas a new 125 kit would take a couple hundred miles at 30mph max
I personally would "heat cycle" it a few times and easy for 50 miles or so then ease it in to a good blast! Always warm it up for a few minutes when it has run in while you get your lid on etc.
