I recently purchased a new Unison Desert Cat 90 from Raceway and I couldnt be happier with the bike . It's a strong running bike and very sturdy . I only have one problem , It smokes alot of white smoke while running . And it's more than just the usual smoke because a friend of mine has the same bike and about 1/3 of the smoke comes out of their quad as does mine .

I might have filled the oil level a little over the line , do you think this could cause the quad to emit this kind of "Smoke Screen " ?

Please help ?

 

Hmmmm I have filled my oil to the top of the tank and didn't have any ill effect on the
engine performance or smoke levels.....didn't know there was a fill line on the oil tank
on the DC.

Are you going through alot of oil on the machine...ours just sips it.

What type of oil are you using and what line are you referring to?

 

I have to use the 2 stroke oil, which I did . I put it in the tank which is under the seat and there is a fill line on the tank itself and the oil is a little over it

 

The oiling system may be mixing too much oil, I believe many people bypass the oiling system by adding a single pull throttle cable availabe at many mini hop up sites. May want to call these guys at www.hetrickracing.com if you want to go that route. Many people do not trust the oiling systems and would rather mix oil with gas themselves. In fact, I will be doing the mod myself.

You may also have a carb/jetting issue, but I highly doubt it. I would also try a different brand oil....maybe a synthetic racing 2 stroke oil.

 

I was thinking of going that route as well. Does the single pull throttle cable make it easier on
the thumb? My kid complains his thumb aches after riding for awhile.

I always use synthetic. Golden Spectro.

Cant remember where I saw the instructions....

 

Sorry to hear you had problems with your Unison bike. I know some people who had ALOT of problems with their bikes. Thats why I try to stay away from Chinese made bikes. I was thinking about buying one for my son a few months ago. I did some research and am now staying away from them. Heres something I found online from them. Hope your problems get fixed.

Thank you everyone for your positive feedback from the Unison line of Desert Cat ATVs. I have some great news I wanted to share with all the Unison riders, and future riders. As most of you may know, Unison is a Taiwan manufacturer. However, sales from Taiwanese manufacturers have dropped 50% since China started manufacturing ATVs. Because of this, some Taiwanese companies have gone out of business. To combat this problem, Unison Motors also has a manufacturing plant in China. The factory in China will be put into use more in order to cut costs in manufacturing the Unison ATVs and give the public bikes at a cheaper, more affordable price. Unison Motors will keep you updated with any changes in warranty. Thank you!

And what manufacturer would you suggest......

 

Unison is actually made in California , It's not a Chinese bike I think . I have a Kazuma also and havent had a problem with it yet ..

This Oil problem doesnt affect the performance of the bike as far as I can see ..it just looks like crap .
