New to Yamaha Gas carts G9

denrosesc · 11-07-2012, 08:28 AM

Good morning all, I am brand new to this forum, I just purchased a 1994 G9.

Its has a bit of a ticking when its running, and seems to lack power on hills.

I have a new spark plug to put in, I am considering adding SeaFoam to the gas, and possible the oil as well.

Am I doing anything wrong by adding the SeaFoam?

Welcome...I would try changing the oil vs. adding the seafoam and drain as much of the gas as you can and replace with new.

You should do some service on it, could fix all your issues as most people don't touch them. That means a tuneup (oil/plug/filter), new drive belt, check/clean/lube the clutches, see where you are at then. You can measure the drive belt they are junk at 1" wide, for a lifted cart wider. They are 1 3/16" new.

Valve lash is easy to adjust, but make sure you seal that cover or it leaks oil on the cooling fins and plugs the engine fins up with dirt/etc., then it overheats.

Some worn engines the balancer shaft in the block gets worn and starts to knock some, it rides in the side cover. Acutally the block/cover get worn not the shaft. Clutches are notorious for knocking, assume it is that unless you can locate it otherwise. Often they get a little better with a shot of grease, no more than 2 shots and make sure it does not come out on belt...its only a bushing in there. Often you can grab it and pull it up/down and feel the play. They are never tight but too much play they start to knock.

Thanks guy's. I changed the oil, installed the new plug, adjusted the valves, checked the air filter.

Gee is .016 too much space between the valve and lifter. LOL

Thanks to this forum, I learned the adj. sequence and the distance..004 its much quieter. also seems to have a bit more power.

Next I will lube the clutch. I am sure it has never been done.

thanks for your input.
