A friend of mine has a 21xd " I think it's an 05"and recently he blew his 300x, well he sold the "X" and bought a new 250xs with a torque master and 1.75 gears and has a 14" plate, I think he's running a turbo top-ot4 that came off the "X",and since it's still in break in he hasn't opened it up yet. Questions are:
what rpm should this motor be propped for?
whats a good set up for this combo? "prop to pad"
what prop would y'all recommend?
and what should he expect out of this combo?
its his first bullet and he never really opened the 300x up bc it blew before he got enough seat time to learn it, but I told him I would ask you guys to see what he might could expect out of this combination. Thks in advance .
