bore it to like 65....maybe some carb mods.....but boring is your best bet for low end....

Or just put a 650 in it.....that should add a little low end but not tooooo much.

Pop the 2 nuts off the exhaust where it bolts to the head and pull out the restrictor.

Many PW50 owners would add cylinder base gaskets to reduce compression and let motor rev higher. Another common mod was to pull guts out of silencer and remove rev limiter. So for a 94 that may have seen many owners you may have a modded motor that hurts the stock bottom end. You might think about checking that cylinder and gaskets are stock and in good shape.

I don't know anything about PW's but it sounds like a pilot circuit problem. Did the bike sat for a while before you bought it?
