Power Mods for a G1 ?

RCDART · 05-18-2010, 12:53 PM

Is there any cheap mods for the G1 to get a little more power to get up hill's? Can the head be milled on these motors or is that a bad idea...

I would first start with a good tune up. New drive belt, filters, spark plug and then a governor adjustment.

Now that is good advice

If you want them to roll, you need a new top end if its worn. Mill the head, advance the timing, even a tiny bit of porting can help. Clutching also helps make it rev higher and take off hard then shift out fast so it drops rpm.

It has a new plug and air cleaner, fuel filter is clean. The belt is in good shape and measures about halfway in the range of tolerance given in the manual i found online. The cart runs good i just want a little more power going up the hill's. How can i adjust the clutch? Thanks all.

It depends the early clutch is better but they stopped making them. They are cast alum, the later ones have a big stamped metal gold-ish looking cover. You can shim the spring in the early one the later has none. Either way cleaning and lubing the clutches and a new belt is the best you can do otherwise. Belts that wear to the 1" are ok on a stock cart but terrible on lifted carts. Also check the motor mounts if the motor moves towards the trans under power it will hurt takeoff and hill climbing, you can tell the motor slows down. If the muffler is plugged it will have less power.
