Hi, is there any possible way to run a scooter engine without any electronics like cdi box or battery? Simply raw engine with connected fuel and with start it manually. I got a old scooter engine without electronics but the engine self was running before we build it out.

PROBLEM: I NEED HELP PLEASE….I have a Kinroad 125cc T-8 Chinese Scooter with a GY6 Motor. I recently removed the Air Filter box for cleaning. When re-assembling the box back to the scooter I noticed a Black Rubber Tube attached to the very Front of the Engine Casing. I think its the Valves Cover. The opposite end of the Tube was not connected to anything.  I can not remember if I removed this Tube when I removed the Filter Box. So now I am not sure where the other end of this tubing should connect to. Does it connect to the underside of the Air Filter Box somewhere or is it just left to hang down wards? At the unconnected end of the Tube, there is a Tube Clip, which makes me think it should or pushed on to something somewhere… but I am not sure.  Please Help Someone…..  Thanks Folks.  Guy J. (Spain).

my sister has exactly the same bike as that.. She had a bad wiring loom on it. so i bought a second hand one and fitted it.. all wires and connectors going to the correct ones.. even held the old loom beside it to check. but now it has no spark..
Ive tested another coil, spark plug, its recently had a brand new stator anyway, so cant be that.. 
But did find that the Reg/Rec was knackered..(had a cracked hole in the rear of the casing).. so got another on order..
Please help.. im getting frustrated with it… if it helps, i replaced the loom because smoke came out from the front.. and the reg/rec actually smells like the smell that the burning smoke gave off..
But surely a knackered reg/rec cant cause lack of spark?? cheers

I have an 06 TNG dr150 that I’m working on for a friend and yesterday I had spark but today I have no spark any ideas

thersten says:

Changing every part of the ignition system is a stupid way of trying to fix it. And you didn’t even mention the spark plug, I guess you can’t make money off that.

Johnnie Ramo says:

hey my scooter has not start, I try to start it but it will not start I try to kick start it but it will not start as well ,, what can I do to fix my scooter please ? the brand is Hyosung

Ron Purcell says:

I have a SUNL SL 150cc scooter that will not start. I found under the seat a black plastic container about the size of a small shaving cream can that has 3 black hoses on the top from the fuel tank and one the bottom is two connectors with no hoses…I can not find the other two hoses anywhere around the engine? What is that container…and would anyone know about the other two hoses and where they would possibly connect to?

Frank Lucero says:

I’m fixing a tank, which has been sitting. Turn the key and nothing, kick start is messed up, but it did start after several attempts. and was at full throttle. Ran out of gas and that was it. Put gas in it tried it again nothing. I put in a new cdi box and nothing. I ran a hotwire from the battery to starter and it turns and turns, checked the plug but there was no spark. Any ideas?

Rich White says:

I purchased a new cdi,coil and stator and installed them myself,i am getting fuel but it will not start.all it is doing is cranking over,any idea what it could be

Michael Lovett says:

Luis Agosto says:

i got a RR 250 ZRX, Race scooter 250 cc RR I scooter. its not holding the charge im tired of buying batteries and chargin it… how can I fix this? what could be the problem?

Optimus Prime says:

Hey Matt, I had my scooter working the other day and then the next day it stopped working? I replaced the spark plug and charged the battery to 75%. Do I have to charge the batter to 100%? I used the multimeter and it is showing 12.9volts. I thought the scooter only needs 12v to begin with. I am charging it again and hopefully to get it 100%.

I’ve had the scooter for over 8yrs and haven’t changed the battery since. But it is reading 12.9volts? Possibly something is else that has caused it to stop working.

Danny Yarbrough says:

Don’t forget to change the spatkplug it can be shot as well. Especially the Chinese plugs that came with scooter.

Sam Notarpippo says:
