?2006/08? Yamaha Vino 125cc - Won't start, Seat Latch By mikey34 (Read 15,013 times)

Well here is the thing if you jumped the Solenoid and it won't turn the starter, I would try a jump either from a carb battery or a car charger if you have one. Reading on a battery it could be still bad and very weak and what its reading is the surface charge. But when you put a load on it they will drop like a rock. That is why I suggest First try to jump the battery and try the squeeze and push start if nothing then with the jumpers on try jumping the solenoid. If it still won't turn the starter then check the wire from the solenoid on the starter if good then one of two things the STARTER is BAD and or the MOTOR IS BINDING. Can you turn the motor over by hand?

Gotcha Rich, Thanks Man, I'll be taking that out of the equation today. Plus, you can see in the pics ^ that carb NEEDS cleaned, and I bet that's my Main issue.

[mikey34]

Yes I can Alley, It WILL turn over when I kick it, and the Headlight is Bright while kicking, the spark is Great, I can see it plain as day even in the sun light. I really think the Carb being FILTHY is the reason it won't start. As for the Electric Start, I think your spot on with a bad battery. It has been sitting in the owner's shed for 2 years :/ No Tending

[jvino]

Is your spark plug wet? If your getting spark and the plug is wet I would believe it would fire?

[jvino]

Oh if it's been sitting ideal for two years in a shed you are probley right the gas in the tank and carb are like varnish. Drain the tank and clean the carb you should be back on the road. Might want to order a gasket kit for the carb. You could try to charge the baterie but it's probley shot.

[mikey34]

Ok guys, I cleaned the carb, but the funny thing is, it was CLEAN, Really clean. On the inside, not one spot of varnish...? I cheated on draining the gas and just added Premium. Prolly gonna have to drain it, and just get completely new gas. I was hoping it would get going and I could just RIDE the bad gas out lol

[jvino]

Mickey you could always try to mix the new gas in with the old gas the problem I see with that is the vino only holds a gallon so it must be pretty close to empty. Mickey I am surprised you own scooter there must be a huge difference in it compared to a gsxr crotch rocket. I am assuming you own one due to your label is that at least. But the vino will get you from a two b without a lot of gas. Good luck hope you get it going.

Thanks jvino, I actually own these ATM,
2008 WFH50-S2 (49cc)
2007 Vento Triton (49cc)
1994 Suzuki GSX-R 750w (750cc)

But I also run a Scooter Repair Business out of my shop building in NW FL. I love any kind of engine big and small. I love these little things man! Great Gas Mileage, Plus, you can tear the entire scooter down in 3-5 hours, depending on hard you want to work on them! I like posting my issues on here though, so as to help someone else that might be having the same issues. 1,000+ heads are better than ONE!

Thanks alot for all of the input BTW guys, I took the carb off and got it as clean as possible. I was AMAZED, that for as dirty as it was on the outside, the inside didn't have ONE spot of varnish! I went ahead and cleaned the Jets and the outside of the carb, this thing as an ANNOYING Throttle cable(Double). Got it all back on and tight, but STILL no Start, EVEN with a small spray of Engine Starter! Gonna pull the fuel pump, make sure it's sending enough...

[mikey34]

This is a MUKUNI Carb too guys, it's funny cause I have 4 SIMILAR carb's on my Gixxer!

Damn I don't see any AIR OR FUEL mixture adjustment on that carb or am I missing it?
Alleyoop
That piece on the BOWL appears to be where it draws the fuel as a PILOT JET would does it have holes on the side of it and if so is that cleaned out.

[mikey34]

Your are right Alley, No Adjustment Screw, However I can adjust the Idle, like a normal gy6 carb. Does MUKUNI make the Roketa/Bashan/Peace Carbs? I can't remember.

I still think I might have some bad gas in the tank, I swear I can smell bad gas... I've just been procrastinating on draining it, hahaha

BTW I put a Brand New Battery in it, NO CHANGE, I think it's Bound up like you think Alley, gonna take it off and clean the teeth, I am right next to the beach, so SAND IS an Issue! lol

[Alleyoop]

Well I would pitch that that carb and replace it and also have only one throttle cable and an adjustable carb to boot.

[mikey34]

Exactly what I WANTED to do! hahaha I dislike this carb, ALOT! It has been a pain, since I decided to take it off and clean it, mainly finding the right sequence to put the TWO throttle cables on! Does this not SLAM the butterfly closed when you let off of it?

[Alleyoop]

HAHAHA, APPARENTLY NOT that is why the two cables(BUMMER).
Tell you what my friend I have 4 carbs ALL BRAND NEW, 2 are KEIHIN CLONES 2 are JAPAN KEIHIN Carbs I bought them JUST BECAUSE HAHA). I will sell you one of the JAPAN KEIHIN Carbs 24mm for $25.00 including SHIPPING i don't know why I bought them but they are still in the original box they came and still wrapped in bubble wrap, they come with a fuel filter. PM ME IF YOU ARE INTERESTED with your address and you can pay me by paypal and I will give you my Paypal email.

I'm a little worried about getting the throttle cable down to a single cable and have it sit right, but I think I can get that solved, just use The UP side and zip-tie the other one to the single cable a little further up the cable. So if anyone EVER wants to put the "Stock" one back on, they can.
