all tunings are really relative and depends on what you want out of the engine. p5 and plus4 engines are pretty tuneable as far as pipe , plug and clutch .

hey Monty, since I'm not building my truggy now
I put the P5XL you built me into my buggy and I'm on the 3rd 3 min heat cycle and @*#° this thing is FAST, got it restricted to 6.5mm on the carb and it's unreal at just short throttle blips, can't wait to get it race tuned!!!
