Start Up Problem - Page 7

longumd · 11-02-2011, 02:38 PM

I see in the manual, if the starter motor will not run and starter relay clicks, there will be three reasons:
1.Faulty starter motor
2.Faulty starter relay
3.Loosen or disconnected starter motor lead wire

Since the starter motor runs in the first place, then stop running and only the starter relay clicks, then is it more like a connecting issue?

Thinking about my bike, it starts having problem after rains and I let it sit for 2 months. It is entirely possible the issue a some corrosion and caused a bad connection?

Longumd, if you want to carry on faultfinding, then the acquisition of a multimeter is a necessity. Unfortunately, if you're not sure how to use one, then a trip to the repair shop becomes the next step.

Yes I have a multimeter and knows how to use it. Also has some common tools.

I will keep on troubleshooting, this time following the manual.

I guess I need some suggestions on what to buy to clean and lube the parts.

The starter looks like a metal cylinder on its side at the front of the engine, it has one cable that connects at the top at the right side, under a black rubber cap. This (black) cable comes from the starter relay (AKA starter solenoid) in your first picture. It is the "other" thick cable, about as thick as the red cable from the battery. Please refer to my previous post as to where to measure resistance.

My son is a UMD student who lives in College Park as well and I'd go there and try help you but I never dealt with carb issues (what I think this is because it turns over and doesn't start) before so I won't be much of a help.
if you don't feel comfortable cleaning the carb yourself you could try a shop. Or maybe there is a "Terp riders" organization where you could get help.

For cleaning the chain, use kerosene. For lubing it, use motor oil. Sparingly. I use a paintbrush to clean it, over a paint tray (to protect the garage floor), paper towels to dry the kerosene off, and a paintbrush to spread some motor oil to lube it.
Don't worry about that little bit of rust on your sprocket. It will wear off with use. Remove the cover and brush some oil on it.

hmmm carb... ok heres a silly question... Have you cleaned your carb recently? If so did you put the jets back in the right way round? Yes I did say it was silly but believe it or not its happened to me before lol

Also 2 months sat out in the rain is not good for your bike mate. Im not surprised it wont start to be honest. Have you put in that new battery yet? Do that, change the spark plug and if it still doesnt work i completley agree with these guys, find a garage and get it seen to by a qualified mechanic. Be careful who you take it to and make sure theyre reputable.

Thanks again!

To 5th_bike: Appreciated, I'm a UMD student too. I'm found Terp Rider on Facebook and trying to join them.

To Peachy140: Thanks for the advices, yes the spark plug is new, I changed it last month.

I tried the new battery this morning, the bike won't start but at least the starter motor works. The new battery is charged (12.8V), after get it installed, I attempted to start. The sound coming out is "B: Starter engaging, but no combustion", I mean, endless "B" as long as I keep pressing the starter switch. So I guess the new battery works much better than the old battery even with jump start. After few attempts, the bike still does not start, then I get the battery off and measured it(~12.55V).

I guess this is the last simple attempt before doing the detail troubleshooting. From your previous reply, I see it is more like I need to do a carb clean? Seems that the starter is working, no combustion came out because the carb doesn't give out vaporized gas to the engine?

I feel like it's a faulty kill switch somewhere. You're just not getting spark.

The kick stand switches on these things are known for going bad. And if it sat out in the rain for a long time, it could be corroded.
To test it, put the bike in physical neutral and see if that makes a difference.

Also, make sure you're using a good bit of choke and that your handlebar kill switch is no turned off.

It should at least hit, even with bad gas or bad vacuum or any of the other things that might be wrong with it.

longumd · 11-03-2011, 12:12 PM

Thanks jonathan180iq

I will try to check the switches.

Sorry I'm not quite sure what do you mean by "physical neutral". I always put my bike in neutral (neutral light on), use choke and the handlebar kill switch is on.

I attached the GZ starter system description, it appears to me that if the the bike has a faulty side stand switch, then the starter motor will not run properly. Since the starter motor is running with the new battery, I guess the side stand kill switch is OK?

**jonathan180iq** · 11-03-2011, 12:21 PM

No, the starter motor will turn over, regardless. What you won't get is spark, so the bike can't fire up and drive off with the kickstand down, which could kill you.

Take come WD-40 or something similar and flick your kick stand back and forth repeatedly while spraying the contact of the switch.
then clean it off.
Do the same thing with your button kill switch.
