What would be the best engine upgrade from the guys at obr for my rampage mt. Was thinkin the 7 HP full mod 30.5 is that what's better for these a 30.5 for the torque. If i don't go that route can I get more power from stock 30cc engine I already got. Ddm dominator pipe
 
If you're comfortable with taking these engines apart, I'd go with a ported head kit and then throw on a DDM pipe. You'd be good to go with that.
 
is obrs 2 bolt 30.5 cc a good start and I already have a dominator. Does ddm sell anything like this
 
OBR puts out good engines, so the 30.5 would be a solid choice. DDM sells ESP engines, which are good engines, as well. They have a fully ported 30.5 that puts out about 4.5 HP.
