Piston port?

The engine, 2 stroke pocket bikes have 2 engines, piston port or case reed. Both are great in their own way and can be modified easily.

i know what piston and crank porting is i race dirtbikes i have a yz125 with a big bore you kinda just mentioned my motor being piston ported most engines are piston ported unless its the 47cc engine cuz thats crank inducted piston port kinda sucks imo your limited to a certain rpm and it sprays fuel out the carb at the split second it hits the down stroke

That's great. Actually there are a lot of case reed dirt bikes most have know idea.
They both have their positives. IMO and experience, modified piston ports need less maintenance during their life cycle vs the case reed. But both have a similar life cycle when modified.

usually you can tell when a reed is gonna go my rm85 is gonna need a new one coming up.these japanese 85's are fukin nasty 6 gears crank inducted 24mm carb and some big transfer ports in the cylinder not to mention the ATEV power valve basically has all the mods the pros are using on a stock bike i try to buy cr80s or kx80s-85s every now and then cuz their pretty cheap just needing a new top end maybe someday ill be able to get a 125 or 250
