Default Considering a gasser

I have built up a couple electric Yamahas, but now I am considering the idea of going to a gasser (G-22, more than likely lifted with 22"-23" tall tires). I don't offroad with my carts, other than an occasional trip down a dusty road so keep in mind that I am looking for some speed mainly. My questions is; aside from bypassing or adjusting the governor, is there any other mod that has good returns for the dollar, be it a modification or a direct parts bolt on?

I would love to hear everyone's top "bang for the buck" performance enhancements for the Yamaha carts.

Thanks guys.

Nothing huh?

Would that lead me to believe that the BIG improvements are bypassing the governor or going right into major engine mods? I would have thought that you guys would have a wealth of bang of the buck information about these things.

depends what you call bang for the buck (aka whats your budget). if you gov is cranked down/removed and you put a torque spring on it it does pretty good. Other than that the next step is normaly just big blocking it

its alot easier to take a jug of gas out to the back 40 than it is to run an extention cord and i dont have one that would reach. thats the reason i go with a gaser. spring it and bye pass the govenor. thats all ive done and it runs everywhere. my parents have electric and they are nice but they dont trail ride. mine has 22s on it and with the tires aired up it will go 30-32. how fast are you looking to go?

Plowmans is making a cam for them now, and they already have a ported head and big carb. and exhaust! Go check out their site!

My G8 will run 26 mph, cruise about 22 mph all day. I drive it about 8 mi. a day in the city. Side streets mostly.

Of course, my budget is always "cheap"...haha

The spring you guys are talking about; is it for the driven clutch or the drive clutch? I would also be interested in which spring you guys are running and the changes you noticed in your performance. Does it simply offer a quicker backshift, or does it alter the shift rate as well? I am fairly well versed in CVT clutching (mainly snowmobile racing), but I am not up to speed on the parts and hot setup for golf carts. Do any companies offer clutch kits or different helixes for these carts, along with the springs?


Ideally, I would love to see 30mph speeds and good response from the cart. Currently it has the governor cranked all the way in, and it is a long way off from seeing speeds anywhere near comparable to that. It only has stock tires on it however, but experience tells me that a taller 22" tire would only be worth a few mph from where it is now.

Does bypassing the governor add a lot of speed, as compared to running the governor all the way in? If it was a major difference in speed, I could see bypassing. However, if it is only worth a 1mph or 2, I would opt to keep the cart governed so that others could drive it more easily.

Range is not a huge concern to me. I definitely drive my carts, but have never had any issues with the range of my electrics. I also would like to keep things fairly quiet sounding. I think a header or aftermarket exhaust isn't for me.

Any more info you guys may have to help convert me to a gasser is much appreciated.

My G9 with 22s will do 30gps with no governor, but some other yamaha have a rev limit mine does not. Another G9 would do 27gps with the governor all the way in. Some newer seem a little slower but some will go over 30gps with no governor. It may be the tires, these are trail pro they are a rounded knobby. I run 14-15 psi in the rears and they measure 23 tall then, 8psi in the fronts they have little weight on them. Lower pressure will slow the cart down with less gearing and more rolling resistance. If I were you I'd investigate putting 25s on it, you may have to re mount the rear bumper/etc trim stuff to do it, but its more speed. You might hit 35 with no governor and taller harder (well not sagging soft lets say) tires. After that you have to go to gears in the trans, or an engine that runs more rpm the stock yamaha is limited to 5K or so unless it runs harder with mods. An 18 vanguard with a rev kit is the fastest top speed I know of, it will rev quite high, higher than a 23, for otherwise stock big blocks. Many say they get 45mph with them. But gears are nice on the road because then you can cruise at lower rpm its not winding all the time.

IMO you don't need or want a clutch kit unless you climb hills. If you clean and lube the clutches and put a new belt on, make sure the engine mounts are good, it should perform nice on the road. They take a primary sled spring and put it in the secondary, with no preload because the spring has no ends, it blows the c clip off because it was never made for that pressure. I guess it works, I modded mine in other ways and pull boats out of the lake so it can be tuned some with a stock spring. You can use the work cart spring too its a little more HD. There is no spring in a yamaha primary. You can also get a cut secondary sheave for a lower gear I did a cart and it sure helps, but still will bog until it moves if the distance is not right. But then put a clone 16 in that cart there is no bog now, but it goes same top speed rpm limited.

If you buy an aftermarket clutch they have springs, you can make it engage at higher rpm for stronger takeoff, but not as smooth.

In my experience gears or 22s on an otherwise stock cart with the gov all the way up or disabled is about a 10mph difference give or take.

I would think a lift and 22s or more would be the first way to go faster, should get you 30mph top speed or so. Second I would put gears in the trans because unless you change the engine to pick up a lot more rpm and some power to push it....its not going to change that much. After gears I would put a larger engine in or otherwise increase power. If you ride roads you will like more gear the engine runs slower, but it will not be good on hills/towing/climbing/etc. or at under 5mph or so. You really need a larger engine to run gears and lift. I guess it depends on what is more important, but like i said if you lift it and put largest tires you can fit you will be around 30 no problem with a gas with no other mods except a governor adjustment.

Stock cart is 12mph, I think 16-18 with governor all the way in? With 22s you will be 28-32 depending with no governor and 25-30 with governor.

My mom has G-22 with governor tightened up and it will GPS 25 mph. 4 passenger with windshield and low pro tires.
Check slack in both accelerator cables at the pedal and at the governor. Most say you need about 1/4", if you go to far it will jerk at slow speed.
