The dealer tells me that I need to bring it in because it might be the electric choke that needs adjusting so that it will start when it is warm. Dealer says that they have never heard of this problem before. rob said on last post that dealer knows about this problem. any way for me to check myself and educate(kindly)the shop. I like the scooter, but am tired of it not starting after it warms up. it is to heavy to keep loading on my truck to bring back home. <em>The C3 is fuel injected. It has no electric choke. We are aware of some fuel pump issues due to the pump sitting for lengths of time (while in winter storage) in fuel containing ethanol. At the time of starting the engine when cold, during the point that you turn on the main switch, you will hear the pump working for about 3 seconds then it stops. Does it make this noise when you cannot start the bike? Yes? - not the pump. No? - replace the pump.</em> I have an 07 C3 that i got new.

I test rode it and it started up fine. After the 2 hour trip home on the back of a trailer in 99 degree weather it wouldn't start. I called a local dealership and was informed the fuel pump on a small number of units swells when too hot and therefore cannot effectively supply gas for ignition. Apparently Yamaha knows this and picks up the tab at the dealership. Hope this helps. I just recently (today) bought a used 2007 C3 with less than 500 miles. I test rode it and it started up fine.

Top speed was normal around 45km. It runs great .But recently it lost a lot of speed maxing out around 30km.I just got it check out .The spark plugs are good and the compression is fine. I was told maybe it could be the cylinder getting them cleaned could fix the problem.Any suggestions I just bought my 50cc Yamaha scooter 3 months ago. Top speed was normal around 45km.

The key is to help your dealer understand how the problem shows itself, how long it takes and get them to experience the "shut down" for themselves. Also, similar sounding issues may not always be the same things, so give your technician as much info about the problem as you can. Please let me know what happens and what the final diagnosis was, you've got me curious. Hi Moogie and Kunzamik2002,

I'm about 6', 200 lbs. Do you think this would be an appropriate choice? I read somewhere that the scooter's weight capacity is only 170 lbs. Many thanks. <em> The owners manual does state that the maximum weight capacity for the C3 is 187lbs. What I would recommend is the BWs125. You can check it out on our website. Below is the link that will take you there. I personally ride the BWs125 every day to work and love it. I am fairly close to your height and weight. The bike has tons of power which is really nice when commuting. I have been commuting to work on scooters now for three years and wouldn't trade them in for anything.

There was no difference from stock for the first 20 miles. Then as I was approaching the downhill side of the worst hill on my route,(a 3/4 mile 5% grade) My scoot suddenly surged forward.(I guess it took the sliders that long to wear in.) Stock, my scoot would quickly lose forwaed momentum on this steep hill, And hang onto 18-20 mph to the top. However, This time it slowed gradually,And halfway up the hill my little mill began to gain rpms until it was slowly going faster before it went over the top, Never going slower than 28mph.If I hadn't seen it I wouldn't have believed it! They also replaced my rear tire with a 140/90-10 which gives a higher overall gear ratio and fits in the space available without rubbing anywhere. Top speed increased from 42mph (with a derestricted variator) to 45.5-46 mph.No mpg figures yet but I expect it to be a bit better as my engine's not working as hard all of the time now.The quoted figures were accomplished with a stock drive belt and variator torque spring.KS Power llc in Indianola, Iowa modified the Dr.Pulley Variator to fit my scooter,(and are the only shop that's doing this right now.)The only part of my warrenties(regulsr + 3 yr extended) that it voided is the transmission.And you guys have been using the same platform for over 30 years- It's as reliable as a claw hammer!To go any faster means an exhust system upgrade, 50 + mph is possible.
