Baja SC50 - where to start? By scooter49009 (Read 463 times)

Hello all,
My first official post.  My hopes are that I can learn alot about troubleshooting and actually fixing 50cc scooters with the help of this forum.

I picked up this scooter from a local guy that just had it sitting in garage.  The typical story.  Ran great.  parked it and wouldnt start back up.  This was over a year ago.  The battery looks old and it doesn't kick start.  I made sure that engine wasnt seized and it would turn over before attempting to pick it up.  Body is perfect and looks like it was well taken care of.  they had taken it apart and I can see a few connections are hanging. 

Curious to know what it might take or where to start in order to try and at least get it to start via kick start.  Batteries are cheap for these so I thought about getting a battery.

Help!  I can provide pics of anything you want to take a look at.  Has key ignition and all parts are there, just a few connections I can't find where they plug into under the seat.

Here are some images I took of the connections that are not hooked up and overall condition of scooter. Second picture down is the only 2 connections that don't appear to be connected to anything.  I figure the first thing I'll do is remove spark plug and replace that but beyond that my step by step troubleshooting needs help.  Also I'd like to drain the gas and the carb because I bet the gas has gone pretty bad since it was ridden last.  They had the main speedo cover off and I took pics of all those connections.  Whatever they tried didn't work.

Ooooooo a cherry,,,,new battery,,, clean the carb and change the gas and adjust the valves ,,,change the oil after you get it lit and BAM!!!!! You gots a runner!!!!!!

Only a little over 2500 miles,,,,a real cherry

cyborg, what about those connections? I'm thinking something isn't exactly connected correctly.

I'm going to replace the battery and spark plug and try it out.

The wires you are asking about go to the CDI. In image # 3 you see a little square rubber strap? The CDI went in it and the wires in question plug into it. She'll not fire a lick without it>

I'm thinking there may not be a cdi currently in there....I notice that boot you show int he picture...but no CDI for those to click into. hmmmmm. Being its sat for who knows how long. What do you think about new batter, new cdi, and for 25 bucks just picking up a new carb. I can keep current carb for a back up and clean that all up.

i would think I'd be well on my way to it starting. That and for the price of a spark plug I'll replace that too!

ps for that 50cc baja scooter what would you recommend for cdi box. What exactly does it do. i went out and looked and there is no cdi box. That explains that!

[cyborg]

Good going,,,someone took it out,,,a battery ,,clean the carb ,, install new cdi and you gots a runner!!!!!!!

[scooter49009]

I have stock ones and performance/variable timing ones.
You need DC CDI.

John,
I can't get any of your links to bring up a web page. Would there be any advantage to a normal scooter rider to use a performance CDI when everything else is stock?

Wix is slow today. CDI alone will not make a big difference.
