250cc scooters Maintenance
250cc scooter maintenance is pretty important. It’s even more important than on a car because the 250cc moped
engine has to work harder and component failure can more easily lead to loss of control.
Perhaps the most important and easiest item of 250cc mopeds
maintenance is to regularly check the oil level and change the oil at frequent intervals. We suggest changing the oil at least every 1000 miles is a good idea. The 250cc gas scooter oil capacity is less than 1 liter and so an 250cc gas scooters oil change costs about $3 and takes about 5 minutes. It’s cheap insurance to keep your engine running for as long as possible. Most of the 250cc gas moped manual recommends changing the 250cc gas mopeds transmission oil every 2000 miles or 6 months. Since 250cc scooter for sale only takes about 100ml of oil (which costs under $1) and takes a couple of minutes to do, don’t skimp on 250cc scooters for sale transmission oil changes. We recommend using Castrol 10-30W 250cc moped for sale engine oil and Castrol 80/90 250cc mopeds for sale transmission gear oil. Which oil you use is less important than how often you change it, though you probably should avoid using pure synthetic oil in a 250cc chinese scooter, especially during the break in period. Once you have several thousand miles on the engine, a synthetic blend may be OK, but you should still change the oil regularly.
Checking 250cc chinese scooters tire pressure regularly is also very important. Unlike a car, a 250cc chinese moped only has two wheels and tire problems can lead more easily to a loss of control and possible injury, so making sure your 250cc chinese mopeds tire pressures are correct makes sense.
Though a standard 250cc cheap scooter maintenance schedule calls for checking bolt tightness every 1000 miles or 6 months, it certainly doesn’t hurt a 250cc cheap scooters to do it more frequently.
Every 250 miles or every month:
Check 250cc cheap moped engine oil level
Check 250cc cheap mopeds tire pressure
Check 250cc motor bike lights and horn
Check 250cc motor bikes battery level
Every 1000 miles or every 6 months
Change 250cc gas motor bike engine oil
Check 250cc gas motor bikes tires for wear
Check 250cc motor bike for sale valve stems for splits or cracks
Check 250cc motor bikes for sale brakes and throttle operation. Lubricate cables if required
Check all 250cc chinese motor bike screws nuts and bolts and tighten. Especially check 250cc chinese motor bikes muffler and exhaust fasteners and front and rear axles
Every 2000 miles or every year
Change the 250cc cheap motor bike transmission oil
Check and adjust valve clearance
Clean 250cc cheap motor bikes air cleaner
Check and clean (or replace) spark plug
Check brake linings.
Check/clean/lubricate brake and throttle cables.
Check scooters CVT drive belt for wear and cracks
Check scooters wheel and steering bearings
Though not exactly maintenance, We’d recommend carrying a basic tool kit at all times. That would include the following items:
3/8″ drive metric socket set
Flat blade and Phillips head screwdrivers
Roll of electrical tape
Roll of duct tape
Pair of pliers
Pair or wire cutters
Flashlight (LED type for long battery life)
Short length of wire
Set of metric wrenches
Short length of fuel/vacuum hose
Spark plug wrench and spare spark plug
A few nylon cable ties
Scooter Brake-In
Different manufacturers recommend different break in procedures. For example most of our scooters manufacturers recommend the following:
0-150km maximum speed 30km/hr
151-300km maximum speed 40km/hr
301-800km maximum speed 50km/hr
801-1500km maximum speed 60km/hr
Of course the speedometer is calibrated in mph and the odometer reads in miles, so some translation is needed. In round numbers these instructions correspond to:
0-100 miles maximum speed 20 mph
101-200 miles maximum speed 25 mph
201-500 miles maximum speed 30 mph
501-1000 miles maximum speed 40 mph
What we recommend is to use the “ride it like you’ll ride it (but gently)” technique. That involves riding pretty gently for the first 25 miles (speed under 30 mph, revs under 4000 rpm), then changing the original Chinese engine and transmission oil. The original oil might be OK or it might be “cheap and nasty”. You have no real way of telling, so change it, then you’ll be sure. You may replace the original oils with Castrol GTX 10-30W in the engine and Castrol Hypoid 80/90 gear oil in the transmission. For the next 175 miles (25-200) you still should take it quite easy with no rapid acceleration, keeping the speed down below 40mph or 5000 rpm, then go ahead change the engine oil again. Since there is no real oil filter (the “filter” is just a mesh screen), changing the oil during the break-in period makes sense since it removes small metal particulates that the filter just won’t catch.
During the break in period try to vary the engine speed as much as possible. This isn’t particularly easy with a CVT scooter since they tend to try to keep the revs pretty constant and change speed by changing the gear ratio. It is good to speed up and slow down and not ride at a constant throttle setting for long periods. Also avoid rapid starts and let the engine warm up for about a minute before moving off when you first start the scooter from cold to allow the oil to circulate. This is good advice even after the initial break-in period too.
It’s probably not a good idea to use synthetic oil during the break in period. Good old dino (dinosaur!) oil is probably what you should use. Synthetic oil may be too slippery and not allow the parts (mainly the piston rings) to “bed in” properly. We suggest to stick with the manufacturer’s recommendation (typically 10-30W) until after the break in period of 500-1000 miles. Then you can switch to a synthetic blend if you want to. Amsoil make a synthetic oil which they claim is specially designed for scooters.
Our scooters break-in technique is to gradually increase speed over the next 300 miles (201-500) and at 500 miles do another oil change. After break-in, the engine oil should be changed at least every 1000 miles as part of normal routine maintenance.
