I bought it off craigslist and I guess the person who had it before me did not like the colors.... so they spray painted EVERYTHING
. from the plastics to the head light to the handlebars.
I have lots of questions so ill just jump right into it.
1. What size tires do I need on the front wheels.
2. Why does it shut off while i'm Idling for a while.
3. Why wont my Electiric Starter work. This one is confusing me because I had it working earlier today and all of the sudden it stopped.
4.Where is my air filter? Should it be under the seat or something. I can't find it because I don't know where it should be.
5.Why do my handle bars wobble when I go fast.
6. What is the best way to remove spray paint from the pull start and the plastics.
7. Does it really mix the oil and gas by itself
Im not trying to restore it I just want to get it into reliable shape. Where I can take it out and ride it,use it for hunting, or just some yard work.
Im new here so go easy on me for all the stupid questions.
Ill post some detailed pics of it tomorrow.
#1 look here on tire size on your model plus for any other parts that might be needed. Browse
#2 Could be loosing compression as the cylinder heats up and the piston rings may not be sealing against cylinder wall. This could be one reason for no idle after it warms up. Check compression,should be at least 120 psi to be on the safe side.If it's at least this much,then it could be loading up with fuel(carb clean,needle and seat needs replacement,etc) or possibly crank seals leaking. If less than 120 psi,you could need a new top end job.
#3 Jump the solenoid posts by the battery to see if the starter works.If it does,could be a bad starter solenoid. If not,then could be a starter problem. Here's a good place if a starter is needed. DB Electrical - Polaris
#4 Under the seat in a gray box connected to the carb,if the box is still on the machine!
#5 Could be worn tie rod ends,ball joints,a-arm bushings or a whole lot of tire sealant in the tires causing the wobbling.
#6 Lacquer thinner,acetone,but it will usually eat the plastic up. Replace the plastic or change your color preference!
#7 Keep the oil tank (located in the front of the machine) filled with two stroke injector or premix oil. ANY good two stroke will be okay,doesn't have to be high$ synthetic oil,just don't switch back and forth on different brands. Penzoil,Wally World oil,Quick silver,etc is fine. It wont use much oil. Usually 4-5 tank fulls of gas to two quarts of oil in the oil tank. It's metered at about 50-1 ratio at all speeds from the factory.
#8 There are NO stupid questions if you don't know anything about the machine! Hope this gets you started.
