Need a little help with our Hyfire 6 AL

[MR.7DUSTER3]

Hey guys ,

I need to boost up the RPMs on the Duster, our Mallory Hyfire 6 AL is set to kick off at about 4300 Rpms and we need to boost it up to about 6000 Rpm s

I read the manual but call me stupid , can any one tell me in plain english how the h#ll to change this thing?

Thanks, Bob

rotary switch in position 6

All three (1-3) of the up/down switches down.

That should be 6K

Thanks, Bob

In the instructions for 6000 RPM:
At end of box set, rotary switch to 6 (arrow points to 6). The first small switch #1 next to the rotary should be down (as it was). The rotary switch is set by rotating with a very small screwdriver. Turn gently clock-wise.

Since the lowest RPM limit is 4500, at rotary position 0, your limit of 4300 means tach or box is off. Going to position 7 is 6250 RPM, so may be what you want.

Set rpm limiters a few hundred rpm higher than you plan to rev the engine to so it doesn't "start" before you need it to.

also you can go to Mallory's web site and print the manual for your Hyfire !
