Zrock, I did something crazy and unheard of. I pulled out the owners manuals for all the ATV's.
The Can Am is good on 87 and E10.
The Polaris is good on 87 and E10.
The Hisun manual has a page dedicated to fuel with a big orange warning! 91 octane or higher and non-ethanol if possible.
Glad this came up and got me to researching. Now I can ride the Can am and Rzr to the local station for fill ups and only use the non-eth in the Hisun's and my old old snow blower.

HAHAHAHAHA, just looked at a picture of the Hisun and noticed right above the fuel cap is a warning sticker about the fuel requirements.

manual? what is that don't think iv seen one before..LOL
Really surprised that the little import is specked at 91. They must have their fingers in the fuel economy as well..LOL

For little guys, they suck up the fuel to.

Manual: changing of gears requires manipulation of a foot shifter. :lol:

i don't find ours to bad on fuel. Last ride was 6 hours pretty sure it was coming back on fumes..LOL.. The little one slept for 12 hours after that ride..LOL

I think we can go about 40 miles on the 1.8g tank maybe a little more. Part of that is because we can ride from our house to the trails but requires running county & forest service roads. The Hisun's end up running at full throttle for the first 8 miles or so.

New Chinese 110cc Quads for my boys
 

Is it good to pour 1oz of stabilizer in the tank of a 110cc atv, and let it run through idle for 20-30 minutes? I've heard of gel packs being in the carbs, and failing to let them run idle for 20-30 minutes causes them to need the carbs cleaned. These are brand new and have never been driven. They were assembled in my face. I'm charging the batteries as I type this.

up until this year i have never run stabilizer in my smaller machines/equipment. Make sure the stabilizer is for the type of fuel your using (ethanol/no ethanol). This is where people run into issues and have gelling. they just toss in some carb cleaner/fuel stabilizer/ water elim and its not compatible with ethanol fuel and gels up. Then they come online and blame the ethanol fuel for the issue

478 miles & 53 hours on the black Hisun 110 and the crankshaft seal is leaking again.
Did a parts search on Ebay and no results. Of all the online sellers advertising Hisun parts, none list 110 parts. Even the Hisun parts page does not list 110 parts. If you Google Hisun 110 reviews, this thread is in the top 5 results. I bought two Hisun Axis 110's for the cost of one Polaris 110 and it was a bad decision. Fortunately I've had excellent dealer support and they are close by.
I would advise not buying a Hisun 110 and spending the extra money up front for a better ATV. If you still want to try the Hisun 110, make sure you have access to a good dealership.
