When you say final drive do you mean back by the rear wheel? Guess I am using car talk. So use what the yp250 manual says?there is only 3100 miles on it,trying to Chang out every fluid in it to make sure it is right. Next will be coolant thanks again for your help miken yes, the final drive is by the rear wheel. it usually contains the clutch axle, a countershaft and the wheel axle. if you are going to service your bike yourself, then get a yamaha issued service/ repair manual for a 257cc engine. there will be some very minor differences between your engine and the yamaha engine, but all the important specs will be the same. i have the chinese version of the 244cc, and the honda issued service manual works great. again yes, the final drive is by the rear wheel, and on my ride, the CVT cover had to be removed to change the gear oil (final drive fluid). use the center stand when changing the fluid. i also recommend getting the best fluid you can get. these engines require very little at each change, so don't skimp on the quality of your fluids. |

Next will be coolant thanks again for your help miken Use good grade gear oil, any name brand. I use the 75W/90W oil myself and I own two scooters with this engine and never have had any issues. JR same here, i've always used 80W-85W-  premium high performance gear oil from NAPA in my final drive. the honda service manual calls for that thin motor oil type stuff. i can only assume it's for the reasons i listed in one of my earlier posts, the small oil galleries and small bearing to case clearances. also be advised that my final drive failed at around 10,000 miles. it's the first of 2 major engine problems i had with this scoot. the second engine failure was with the engine itself, and put my ride in the back yard. one more thing for the OP: the phrase final drive can be somewhat confusing because of the parts used. there are 3 basic parts to the final drive. the input shaft, the one the clutch attaches to. the final drive shaft, the one the wheel attaches to. the countershaft, the one that connects the other 2. the word transmission usually applies to the entire CVT area, variator, clutch, and final drive. we call it a CVT, but either CVT or transmission will do. the phrase "twist and go" is sometimes used to describe our type of scooters. oh yeah, one other thing: when you say the right side or the left side, which side of your scoot are you referring to? the "side" is referenced with you sitting on the bike. the "left side" is the left side when sitting on the bike, even when you are standing in front of it looking at the bike. |

The Roar has a tendency to overheating. We had one member here who bought two of them and while out on a long ride (about 130 miles) it got so hot it shut down. Before I ever went out I changed the coolant for made in USA aluminum friendly stuff, and rode up a 4000 foot elevation while running COOL. That's why doing a fluid dump is one of the best things you can do for your import scoot,  |

On the Yamaha variant engines I would use the specified fluids in a decent synthetic especially if you ride in hot weather.
For coolant Engine Ice on our Sunny Florida Roads does make a difference in cooling system efficiency and its non-toxic. With Engine Ice in my Aprilia 250 I have found that the cooling fan gets the job done in a fraction of the time at traffic stops as it did with traditional coolant and now only runs for a few seconds at a time instead of taking a number of minutes to cool things back down.
Follow the directions and flush your cooling system with a mixture or distilled water and white vinegar followed by a thorough flush out with a few gallons of distilled water before adding the Engine Ice Coolant and then flush and refill every two years doing the brake flush at the same time and you should be Golden.

Rockynv what part of so fl do you ride, ILive in ocala St Pete/Sarasota however I will ride the Aprilia to Wachulla or even St Augustine, Venice, Naples and may take a ride down to the Keys. The Aprilia Sport City is a different class of 250cc Scooter and crossover between a Scooter and a small Sport Bike for lack of a better description. The only limitation I have found is the 2.25 gallon fuel tank making it so you need to fill up more often (every 2 hours/150 miles) on long trips. It is a shame that Piaggio has restricted Aprilia to only producing a 50cc Motard Scooter and has even stopped them from producing their 50+ mph 50cc DiTec 2 Stroke scooters. The only large scooter from Aprilia now is an 850 and Piaggio is not allowing it into the US. |
