if i wanted more low end power what could i do?

Bored nozzle, lightened flywheel, and a high compression head would all help low end. Also, a flow control valve gives a little more low end for cheap

you can get all the power you need out of the 440 if you do the right mods.

there is only a 25 hp difference between the 440 and 650 but there is a big weight difference. the 440 is so choked off that it is not that hard to get the horse power up to the 52 that the 650 has and the cost will probably be way less than the conversion.

the 750 mod is harder to do cuz it has a different ignition that is less compatable with the 440 /550.

What are the right mods to do to get more power out of a 440? I have one also which is lil gutless for my liking. It has rideplate kerker pipe oversized pistons but stock head and intake(intake def next thing to do) but I’m not convinced tht I’ll get the power I’m looking for out of it still. I used to own/race a limited 701cc superjet and my 440 is choice but not grunty enough. Any advice would be appreciated

What would those mods be ud suggest I have most on my 440 apart from head or carb work really already and want more power
