Baker,

First off, you can buy the grease at any autoparts house that carries the Permatex brand of products. It is called "tune up grease." If you cannot find it there, ask any cable television guy for some. The grease is silicon based and it will allow the electricity to flow while keeping the water out of the connections.

Take the front plastic off the atv and at each electrical connection open the connection and apply a fair amount of grease. If you do this at all the connections, you will never have an electrical problem. I do this on all of my atv's regardless of the manufacturer.

Next, on all of the youth atv's with the CVT auto trans, you will find a small vent tube just in front of the rear sprocket on the sprocket side of the engine case. The tube is about 3"long and points straight down. Take that tube off and replace it with a longer tube that can be sip tied to a high point on the frame. Take care to make sure the end of the new tube points down so that water cannot enter. -- Also note that you should change the gear oil ever 2-3 hours of riding. I use automotive gear oil.

Depending on the engine that SUndiro installed in your ATV --they have used different models-- you may have an open vent system going into the CVT transmission cover. This is the large cover on the side opposite the front sprocket. If you are going through water, make sure that if you have any vent openings, they are sealed. There is no harm in removing any vent openings to this cover and blocking the holes.

Finally, the stock air box will cause sudden death to your atv in water. Remove the entire air box and replace it with a UNI foam filter. To protect the foam from water, fabricate a shield out of aluminum. Note the foam filter is the best for keeping water out of the engine. ONce you go to the foam, you will need to increase your main jet size. If you cannot find the jets, use a #68 drill bit to start. Do not change the air pilot or needle position.

2 stroke oil. Take your pick for the injection system. Just make sure the cable adjustment is set to allow maximum oil flow. If you want to make sure your engine will last for years, switch to pre-mix. This will require some additional work that I dan describe later.

 

thanks for the tips. Just waiting for the delivery.

 

Got the Sundiro Ridge Runner 90 Yesterday. $1499 delivered from eoexpress.com. Prices have since gone up.

Not much assembly (battery, oil & gas) Adjustments were needed on the brake cables, chain, air filter and tire pressure (10+ lbs in the tires). Also had some tune-up grease handy. The instructions (5"X8" card) and O&M are slim. Buying on line is not for the mechanical novice.

The mini has plenty of power. The suspension and handling, as expected,are not up to par with our Honda ex and will take some time to get use to.

We took it through most of our trails which include downed trees, brooks, mud and rocks and it handled itself admirably.

So far so good.

 

When you are ready to add some performance, drop me a line. I have all the parts for mild to wild.

Your tips have been right on so far.

You said "Also note that you should change the gear oil ever 2-3 hours of riding. I use automotive gear oil." Where is this gear oil?

 

There is a little black plug on the top of the engine case about 3" forward from the rear of the engine (about 1" in front of the rear sprocket). This plug will unscrew standard thread. Use it for filling.

To drain the oil, look below the engine case (directly below the little black plug). It should be a 14mm nut that will be the drain.

Don't pay any attention to the manual for filling info. I add 80w automotive gear oil until it is at the bottom of the threads for the fill plug. As long as you have installed the long vent tube, this will not be a problem. The extra oil helps keep things cool and is very important to gear life.

Some day when you have the side cover off the engine, remove the rear gear cover and clean out any metal particles. I JB weld a small magnet to the bottom of the gear case to help catch the metal particles.

Good luck!

 

My son had a Eton 50 in 99 it was a good starter quad.But had carb problems i had to work on it all the time.A friend of ours has the same problem on his youngest sons 50. I looked around quite a while be for deciding on a 125 Breeze Yamaha for my 9 yr old . It is 4 stroke plenty of power and automatic with reverse.I dont have to stop and turn him around when he gets in a tight spot. Brad 425 magnum 4x4 400 sprortsman 125 Breeze
