[ant1h3ro]

hey guys i got a 94 sportster its an 883 its fun and all but i need some more power since im used to my 1500, i want to convert the 883 to a 1200 or more but need some help in how to go about this... what should i check, do, or consider. thanks again. would it be better to bore the cylnders or jus get a kit with the new ones already in? do i need a new air filter for it as well if i go with the conversion? anything? thanks.

Hammer stuff is legit. Big power and killer customer service to boot. Worth every penny to do it right. Remember though that there's a bit of ancillary parts not included in any kit. Pipe, air filter, ignition, clutch etc.

xlforum has a couple really good threads showing every step of the conversion.
