1991 Yamaha G2a Lift, tires, suspension

bekind

Hi

I'm contemplation to lift my 1991 G2a, larger tires that can handle the sand better, and finally a rear passenger seat.

My concern with the lift is that my neighbor has a 2005 Yamaha (not sure of the model) which was running fine, until he put in a lift. The cart handling is sluggish and the overall performance has suffered ever since. For instance, his cart is now unable to climb the same hill back from the lake. Mine can make it up the hill with two riders. He regrets lifting the cart and wish that he hadn't done so.

1- What drawbacks should I expect by lifting the cart?
2- what type of lift and size would you recommend?
3- Should I add consider replacing the suspension? especially now that I'm adding the rear seat. which would you recommend?
4- What type of tires to you recommend for this cart.

Please note that I'm neither looking for crossing the Sahara on this thing nor have it win the show case. I just need a cart that can take me to places with little worries about getting stuck in the sand. Any thoughts are appreciated. thanks.

BGW

Ok here I go. I am a HUGE fan and pusher of the Pachanga lift for Yammy carts. Easy to build and you can make it sized to fit your needs. I built mine for a grand total of $60. $10 for a receiver tube from Harbor Freight and $50 for the shocks off ebay. I made mine 8 1/2" tall 6" wider (3 per side) and 3" forward. I have beat the ever living crap out of it for well over a year and it has held up so much better then I expected. I had 24" tires from another cart so that's why I went so big. But going that much wider it's more stable off road then when I took it down the same trail stock. I had some 1/4" steel laying around so I didn't have to pay for steel. Basically you build a set of 4 brackets that will be welded into the top (and sides for strength) of the receiver tube so it bolts into the factory a arm location then make some brackets to bolt the a arms on the bottom of the receiver tube. Most people doing this kinda lift goes with about 5" lift and 2" wider which is really easy to do with some angle iron steel and the receiver tube. One of the best parts is you get a front receiver hitch. It's so nice to park a trailer when you don't have to look over your shoulder.
Ok as for the performance part. Generally you lift a cart to fit bigger tires. Bigger tires effect your overall final ratio and bigger tires is the same as installing high speed gears. You loose torque but gain top end if you can get there. On gas carts there is a number of things you can do to help with this. I did a performance jet and torque spring from CPP hand I can spin my 24" tires in dirt with the other wise stock engine. It pulls better now then the stock config. If that isn't good enough for you there are more options such as having your rear sheeve machined, timing advance keys, double cogged belts and new performance drive clutches. If that still isn't good enough you can always drop in a big beefy briggs V-twin and have all the power you will ever need.

@JcXtreme

Thank you for the reply and the information.

I have spent great deal of time on the forum, which have been great source of information, but I'm really lost when it comes to the lift, rear seat, and shocks.. there are too many options and opinions that I can't seem to make up my mind. At the end of the day, this is simply what I'm looking for:

- A rear seat for kids
- Suspension solution so the tires don't grind against the cart body. As of now, anytime someone sits on the back, the cart sinks to the floor.
- Better tires so I don't get stuck in the sand.

I would prefer to just add the seat, replace the tires, and suspension to resolve all three issues if possible without lifting the cart at all. But my understanding is that may not be possible. Please advise. Thanks.

I went with this rear seat on my g9: http://mmvehicles.com/conv/EC/EC_conversions.htm

I had the same issues with my rear squatting and went with the McMaster springs found here: http://www.buggiesgonewild.com/gas-y...-g9-build.html

Upgrading to these helps immensely! I would think going to a more aggressive tire in the back would def help with traction as well! Good luck!

You can put these on a stock cart http://www.jcmotors.com/p-27198-carl...x#.UInxBWdKySo

You have to decide what you want. If you ask me I will say get a lift that fits 22 tires because there are lots of choices and its more gearing/speed than a 20 inch. I would say get atv tires they are much tougher tire and don't get punctures, but in the sand it may not be that big a deal. I would say spend a little extra and get some cool looking wheels, you don't need the coolest, but if you keep the cart you will have those wheels a long time it may be worth it to have something that looks respectable. Ultimately it will depend on your budget. Also note offset wheels make the cart more stable and help with the rubbing issues (get rid of them for the most part).

If the guy has less torque and can't go up a hill, that is because the tires geared it higher. Most people mod the clutches with a lift because of this. You get a cut secondary sheave and a good belt it will help, some put torque kits in, whatever the case your clutches should be cleaned, checked, lubed to work properly few people ever do that. You will not get all your 9hp to the ground if they don't work properly.
