Did you check the tether on the back. Disconnect it. You dont need it. Does this have remote start? Is there spark and fuel? Did you clean the airfilter. Another problem is they have had problems with valves bending or the valve guides falling out. Is there compression? What have you checked exactly?

Do you have spark? Have you checked to see if fuel is getting to the carb/cylinder? If you have spark you can always put a little starter fluid into it. If she starts but quits shortly after, you probably have a fuel flow problem of some sort.

I have found that if keeps killing batteries...
Everytime I want to start it now, I just take along my charge pack. I drain the bowl, fill with new gas and jump...she fires right up....
What is best way to find what is killing the battery...???

goodguy52,
If you run a search for SunL in this forum and the Raceway forum. You will find that many SunL owners have had the same problem. The threads will point you in the right direction.

you cant just unplug the connection on the tether kill switch on the back. if you pull the black plug off the back you will notice that it pushes in a pin. i had to use black tape to hold mine on,after a few bumps it would come unplugged, but still be connected. secondly, for no reason it would not get fuel. it would show in the fuel filter but the fuel hose some how was lower than the carb. the gas would come out of the tank and into the filter but could not go back up to the carb. i used the hose from the gas cap, because i couldnt find one at the local auto parts store. i deleted the filter and ran a straight line from the tank to the carb. i'll eventually get a filter in there but it works for now. i really had to push hard to get that line on the tank. the connection for the tank on mine was alot bigger than the rest of the connections. hope this helps. and please let us know if you get it fixed so others can fix there problem also.

I bought my daughter a SUNL 90cc and it ran great at first. Now it won't start. I have replaced the battery because it wouldn't keep a charge and I have also replaced the spark plug. I can get it to turn over but it won't start. Any help?

I have read the other suggestions on this forum and have been trying them for about a month. The reason I posted this again was to see if I could get some new suggestions.

I have checked the very basics. It has spark, The air cleaner is clean, I have fuel in it,I have bought a new battery and it now keeps a charge. Unfortunately I am new to the ATV arena and I am not very mechanical.
Questions.
1.were do I inject the carb cleaner and please be specific.
2.How do you check for compression
3.is it complicated to get into the valves and valve guides
Sorry but I am learning.
Thanks for all your help.

thank you very much I will let you know how this works out.

yeah but if he does a search for his info smb, what will the rest of us do? we won't be able anwser the same old question.
MODS WE NEED STICKYS FOR THESE PEOPLE on top of the thread section
that way it stays at the top.
bike wont start
bike wont run
bike wont roll

1) check for spark pull plug and ground end of plug to the head (high voltage) make sure pretty blue spark and not weak spark
2) if you have spark remove air cleaner cover get can of starting fluid and squirt in to the air box (be careful not to much) squirt while turning bike over not alot
3) if it still don't start go to your local auto parts or harbour frieght or something like that and get a compression gauge( some are just push on some screw in hole whichever is easier I prefer screw in type) remove spark plug and insert gauge turn bike over 4 or 5 times see what gauge says and thats your compression.
try this and let me know what happens

I just purchased a SunL SLA-110KB for my son and I also had problems with it starting. I checked for spark and to my suprise NO SPARK! To make a long story short, I found the problem to be with emergency shutoff switch system. First the wire that comes from the handbrake down to the main wirining harness under the front light cover was a bad connection. Fixed connection and I got spark. Also I had a small problem with the shutoff switch on the left handlebar, I found that you need to push in on the red button if you use this switch to shut off the bike. I actually had to push it a few times and move it to the right and left (I now use the key to shutoff the bike).

I don't know whats on this forum, but I googled the same problem a month ago and found something about some "gel" in the carb for shipping causing a lot of problems. I sprayed in a bucket load of carb cleaner and watched a yellow goo flow back out. After that it has run quite well.

When you get the engine running and ride for a while then shut it down does the battery remain dead or does it take a short charge.
The charging systems on the small machines usually they just maintain a voltage 2 or 3 volts higher than the battery voltage (12 volt) this puts an unnessary strain on the charging system.
Charging system when battery is at full charge should produce 12.5 to 14 volts to maintain the battery while running.
Does the battery die when the unit is shutdown over night?
Well get a volt ohm meter and test the DC voltage across the battery making sure the polarity on the battery Markings correspond to the proper polarity. Double check if the battery is not reversed polarity, just another precaution.
Start the machine connect the volt meter across the battery and rev the engine to see it there is a reading higher than 12 volts.
If not see if the regulator rectifier is functioning properly. Two wires from the startor follow then to the rectifier. See if there is a voltage difference when you rev the engine This should be an AC voltage setting on the meter.
See what results.

I think that this old post was already addressed in 2006... BUT
And this fellow attached his problem information to it instead of making a new thread.
I have no Idea why but I think that this person may have thought it as a catagory of machine instead of catagory of an issue.
