Carby I need help figuring out what carb i should get for my 100cc engine.

[Grantrocks]

So im trying to decide what carb i should get as an upgrade for my 100cc engine. I dont want to modify the engine in any way, so no porting or anything like that. I just want a better carb for my engine. Any suggestions? I want to do a PWK carb but im not sure if its compatible with the engine i have. Also what size carb should i get 19mm, 20mm, 21mm, 22mm, 24mm?

If you have a otherwise stock engine just stick with the BoFeng and order a high flow filter. These BoFengs are surprising how much HP they can support. If you absolutely need to, a past member here found that you can take a mm off the top of the carb throat and get a bit more out of the tip end, but it's easy to go too far.

Thank you.

Thank you.

No problem! These were actually proven to be great upgrades by @WillitBoost on his dyno. The air filter improved HP by .5hp and I don't recall what the bore modification did, but it only added to top end.
