I Alabama, if it's powered by an engine and ridden on the street it must have Insurance, be registered and have a license plate...It's about $$$$:)!

Mine does the exact same thing. If I take off the fuel cap off, it starts right up! I replaced the seal on the tank and cleaned the cap vent. Now what? The dealer says the recall was already done.....

To deal with all pump issues call Yamahas Customer Relations at 800 962 7926...Have your vin # handy...(It's on the frame, behind the small oblong panel right at ankle height, when you're sitting on your scooter.) There's a Lady Supervisor on the switchboard from 0600-1000 Hrs California time, that knows about the C3's pump issues & who's been authorizing free pump replacement, parts & labor, since I researched and found this 800 number in the fall of '08...The Fastest & Best Way to do this is to get up early and call,& call,& keep on calling asking for,"The Lady Supervisor, who's familiar with the C3 Scooter's Fuel Pump problems," until you get her! She will tell you which Dealer in your area to take your scooter to, to have your pump pressure tested & replaced...Do Not, go to a Dealer...Let Yamaha Send you to one, to expedite the process...Gabe

It doesn't matter how old your scooter is, how many miles is on the clock, if you bought it at a yard sale, or purchased it brand new...The ongoing Fuel Pump issues should have been dealt with by an Emergency Safety Recall the same as they did the Crankshaft/Connecting Rod problem...Now that it's getting hot outside again,if you're having starting, problems when cold, or after left outside in the sun...Or, if your scooter stops going down the road, or at a stop sign and may or may not restart...(800)962-7926 is the way to contact Yamaha Customer Relations with fuel pump issues...Call early in the morning 0600-1000hrs (Pacific Coast Time)& there's a lady supervisor working the phones that's aware of the history of the XF50 Scooter's Pump woes & has been authorizing pump replacement,(Parts & Labor)Have your vin# handy (It's behind the long skinny panel just in front and above your feet, when you're riding your scooter.) You have a MUCH better chance of success getting this work performed free of charge, calling this 800# FIRST and letting them contact a Dealer for you, than doing it the other way around! Gabe
Hey Gabe, I just bought 2 C3s and left one in my drive for a couple hours and then it won't start-you know the problem. Ive taken my bike to a yamaha dealer and they want $545. Ive also called yamaha cus. rel. and they said to have the dealer call and see if something could be worked out with the cost. Is this the way to work it? The bikes are 07s and this bike has only 320 miles on it, the other is 590 miles.

I'd get my scooter away from that dealer asap...You need to call Yamaha First and let them tell you where to take your scooter...It Should Not cost you anything! Keep calling that 800# until they tell you to take it to a Dealer to have the pump pressure checked... Gabe

I have 11,000 miles on my '07 model, with no issues with the forks cracking. I did have the forks overhauled with new parts + serviced with 20wt fork fluid,(Stock fluid is 10wt.) at 4,000 miles when I blew a seal.Now she rides like a much larger scooter.$$$ well spent! Has your '07 model had the Connecting rod/crankshaft recall C/W? You can call Yamaha Customer Relations at 800 962 7926 with your vin# handy.(It's behind that oblong plastic panel, right above your feet when you're riding your scooter.)If anyone has any starting or quitting,(fuel pump)issues. These are also the folks to call, instead of going to a Dealer.....Gabe

At about 2,500 miles, I bought an aftermarket exhaust from www.jiangwayne.com/ & installed it. I weighed upwards of 270lbs then, with helmet, jacket, gloves, & boots ..It had an upswept tailpipe that directed the hot exhaust towards the right side cover with my big butt on board & it was warping the plastic...So, I found an aftermarket Nitrogen over Oil shock absorber with an adjustable preload spring (Like on a motorcycle.) on EBAY...If you weigh more than 180lbs get the 235mm shock...If you're lighter, the stock 225mm length works fine...The weak factory rear shock was dealing with a lot of forces that the frame was dissipating & passing onto the rider's butt. However, the new Real Shock was vectoring these forces to the front forks...I blew the right fork seal within a thousand miles...I own two '07 C3 Scooters & have the same shock & fork mods on each scooter.The heavier fork fluid solved the problem...Gabe

My 2007 Yamaha C3 scooter has a strong gas smell when it is in operation.
Is there a way I can lean up the mixture? Is that even what I need to do?
I just bought it used and am in the middle of doing some minor upkeep.
Brakes, drive belt, clutch, primary w/ throw-outs, cleaned fuel screen and oil
cone screen, coolant, oil, etc..

Can't figure out what's wrong with the rich fuel.

Can anyone help me on this one?

I finally was able to get my C3 out for a putt today, It now has a whopping 3 miles on it. I warmed it up and twisted the throttle to wide open held it there for about a quarter mile, the fastest it went was about 33 mph. Can anyone tell me if the speed will pick up after it has a few miles on it and breaks in? I am a big guy 6'4" 330 lbs, maybe that is all my fat ass can expect out of it. I must say it is a fun machine to ride...

Hey Gabe, what do you think......????
I have. A c3 it's pretty good on gas I'm 330 pounds 6'5" n my wife told me I was doing 40mph ..... I would like a stiff shock or adjustable one n is there any injector upgrade for it
