I am currently awaiting the delivery of my daughters Roketa Mini 90cc from Raceway and would like to know a few things before it arrives. Any help would be much appreciated. Please don't preach about how much Chinese ATV's suck because it is her very first and I am not spending $1800 on an ATV that she will outgrow soon or not even like. So here goes:

1) Should I use regular unleaded fuel or Premium unleaded in it to get the best performance and longevity?
2) Is it OK or recommended to use a high quality synthetic oil in the engine or just use regular oil?
3) Does anyone know if a larger rear sprocket is available to lower the gearing on this model?

It has not come in yet so if you can offer any more information on it I would be very grateful.

Thanks

 

1. Use regular unleaded fuel. DO NOT even think of using premium unleaded.
2. Use regular motor oil or use 4 stroke specific motor oil. MAKE SURE YOU CHANGE THE OIL BEFORE YOU START RIDING IT. Change the oil on a regular basis. I change mine every 12-15 hours of use. It only takes a quart of oil and this is cheap insurance. By changing the oil regularly you can also inspect the oil for metal fragments.

Make sure you check all the fastners, bolts, etc. and use blue loctite. Lower the tire pressure to around 6-8lbs. Make sure this bike has a gas filter, if it doesn't then put on in between the fuel tank and the carb. Good luck!

 

too right mustangman. premium unleaded causes a lot of problems fouling plugs in carburettor engines because it is way more dense than regular. Yes the oil in the geabox will be out of the sump of a Shanghai taxi .. dump it!

 

If you have any questions about available parts, call John at Raceway.

 

Thanks for the input guys. The bike was delivered yeaterday. I inspected it for shipping damage and put it away until I can assemble it this weekend. I took the owners manual off of it and noticed that it is a very poor excuse for a manual. I think they jsut made one for all their bikes in general becuase it says to add 2 stroke oil to the gas, shift gears with the gear shifter, and add 10w/30 to the gearbox. Im quite sure this is a 4 stroke and a transmission without a gear shifter. LOL! I will definitley change the oil before starting it like you said. I keep reading about some kind of gel that may be in the carb....what is it and how do I check for it?

 

Just an update :.
My Roketa Mini 90 came in this week and I finally got a chance to assemble it and get it running today. I went over it and used locktite on all the bolts that I could reach and changed the oil prior to starting it. It fired right up after 4 hits of the starter and runs very well. I will go ahead and say "BUY SPACERS!" as it will tip over fairly easily if it is turned at any speed other than crawling. I will be looking for some Monday morning. As far as needing sprockets....I really dont see a need for them. That 90cc engine has got plenty of "umph" even with the throttle limiter backed all the way down. If you back down the limiter and your child wants to climb a steep hill or come out of a ditch, then you may want to look at some more low end torque but while they are learning I think it is going to be just fine. The manual that comes withthe ATV is HORRENDOUS!! I think they made one book for all the models they make because it talks about adding oil to the gas and changing gears with the gearshifter and the grammar is much worse than the average teenagers these days. There is also NO instructions for the remote keyfob that operates the alarm and remote shutoff. I used it to shut off the bike (just to test it) and the bike would not start again. I started tracing wires and found a fuse under the seat that had blown when I used the shutoff button. I replaced the fuse and it has been going fine ever since. It is only the first day that we have had it but so far I think it is well worth the money it cost. Time will tell.
Make sure to check your body when you unpack it. When I looked at it on the delivery truck everything looked fine but when I took it out of the metal shipping cage I noticed that one of the brackets that holds the body to the frame was broken off. No big deal yet, just vibrates a little more.
