Those brake light switches are connected directly to the brake light bulbs. Most are too cheap to take the current of standard filament bulbs and especially so if your scooter tail light assembly has two brake lights. If you must keep the standard filament bulbs due to state regulations the best thing to do is install a 12vdc relay so the relay passes the current to the bulbs while the switches only pull the tiny relay coil. The easiest and cheapest way to go is installing LED bulbs. All you do is remove the old filament bulbs and plug in the new LED bulbs.

Me too! I was very lucky. I'm ordering a new Linhai AEOLUS 300 in a few more weeks. The weather here in Alabama is starting to break and I have completely recovered from the wreck. It was the worst motorcycle wreck I have ever had. I'm 55 yrs old and started riding a Sears Allstate Moped when I was 12 yrs old. A wreck is not going to make me stop riding.

I had just rolled over 14,000 miles on my 2007 JCL MP250 when I got run over by an out of control car. Engine oil was changed at 300 miles and then at 1,000 miles and every 1,000 miles after that. Valves were checked and adjusted at 300 and 1,000 miles and then checked without need of further adjustment every 3,000 miles until the scoot was totalled in the wreck. Final drive oil was changed at 300 and 1,000 miles and then every 3,000 miles. I replaced my stock headlight bulbs with BA20D 35 watt halogen lamps. I did not want to chance using 55 watt lamps due to the Shark amplifier, speakers, and XM Satellite radio audio system I was running on it. This Scoot replaced a TANK 250 with a CF-Moto engine. I rolled up over 60,000 miles on it using the same service intervals. It had started using oil and was blowing blue smoke. The body panels were ragged and needed replacement. The radiator was weeping around the solder joints and needed to be replaced too. After adding up the cost to rebuild the old TANK or just buying the new JCl, the new JCL won the low bid contract. I still have some of the old TANK Scoot. I've been selling parts of it to a couple of people that have that model as well.

First thing to do is pull the bleed nipple out of the wheel cylinder and wrap a couple of turns of Teflon pipe tape around it. Don't cover up the little hole with tape! Air can sneak back in around the threads and the pipe tape prevents that. It also prevents the threads seizing up in the cylinder threads so the nipple will turn freely the next time you need to bleed the system. You also must have a tube and a bottle connected to the nipple. Put a little brake fluid in the bottle so the end of the tubing is flooded. The bottle must be below the brake cylinder. This acts as a check valve so air is not drawn back into the nipple and cylinder as you bleed it. Fill the master cylinder with brake fluid, put the bellows back in the fluid reservoir, and attach the cap. I don't understand why it's necessary to cap the reservoir but I've never successfully flushed all the air out of these brake systems without doing it. Yes, it's a pain in the ass but if you don't do it you'll never get all the air bled out of the system. On front brakes with the anti-lock device air can hide in the anti-lock device. You can flush it and it feels normal but a few days or even a couple of weeks later the air comes out of hiding in the anti-lock device and you'll need to flush it again to remove that last tiny bit of air. I've made it a policy to bleed the brakes on these little buggers once a year flushing out the old brake fluid. These systems are so small even a little moisture or other contaminates can quickly degrade performance.

n4 nice the problem is if the stock cluster is not working and one can not fix the problem , moding or replaceing may not work either . What I mean to say is if the falt is not the display and the wiring to the display . replaceing the display you will have the same problem . John The entire stock cluster would go away. I would replace it with a sheet of aluminium to fill in the hole. All of them are flat so cutting a new panel and mounting it would be easy. The Acewell meter would simply mount to it's surface with the wires passing through a hole behind the meter. Acewell meters use only the fuel gage sensor and perhaps the coolant sensor if liquid cooled. Illumination is contained in the Acewell meter so just hooking that wire up to the tail or head light wire would take care of the panel illumination problem because that problem went away with the old panel. The aluminium panel can be painted to match it's surroundings. There may be a lot of unused area which would allow adding lots of other accessories like a GPS or perhaps a radio.

That's what I thought so it will apply to the 257cc also because the only difference in the engines is the bore. JR The Linhai 300 (275cc) Scoot engines can come with one of two different stators. The standard stator and a high output stator. The standard stator is common on 260 and 275 engines. UTV's and some ATV's come with the high output stator. If assemblers run short of standard stators, magnetos, or engine cases they will ship scooters out with high output stators. High output stators are available for purchase but you can't just swap out a standard stator for a high output stator. You must replace the magneto and right side engine case as well. If you got really lucky and got a Linhai 300 with a high output stator and it goes bad, you must replace it with a high output stator. To make sure you order the proper stator you must measure it. Standard Stator: Yamaha Linhai 260-300cc Stator 18 Coil Found in many 260-300cc Scooters, ATV's and UTV's OD=93mm 3 Pin in 3 Pin Female Jack (all yellow) 2 Pin in 2 Pin Female Jack (1 Blue 1 Yellow) H=26mm Center Hole ID=35mm High output stator: Yamaha, Linhai-Lifan 260cc-300cc Stator 18 Coil This is more common in the Lifan linhai based Scooters, ATV's and UTV's OD=104mm ID=42mm 3 Pin in 3 Pin Female Jack All White or Yellow 3 Pin in 3 Pin Female Jack 1 Green, 1 green w/white stripe, 1 Blue w/White stripe 1 Blue ring terminal (engine side) I'm seriously considering ordering a high output stator, magneto, and right side engine case if my Linhai 300 I am planning on ordering in February comes with a standard output stator (which it most likely will).

With so many Chinese Scooters and Motorcycles showing up with digital instruments we all know we'll need to find a solution. As for as this problem goes our analogue panels suck too! Sure, the Speedometer works but they are not accurate at all and some of us prefer miles instead of kilometres displayed. Acewell manufactures high quality and dependable digital meters for most any scooter or motorcycle. Instillation is also simple. The speedometer uses a sensor that straps on the lower fork leg that is tripped by a magnet attached to the rim. The tachometer connection is just the end of the wire wrapped around the spark plug wire. Just wrap it around 2 to 5 turns. If the tachometer is unstable when the engine is running simply wrap more or fewer turns around the spark plug wire. The fuel gage is programmable for different fuel sensors. If it reads incorrectly just reprogram the meter using one of the other resistance ranges. If you have an ohm meter you can quickly figure out which setting to use. All fuel sensors have 3 wires coming out of them. Connect your meter to two wires at a time and note the highest resistance reading. Use this reading for setting the fuel gage meter. These meters can be ordered with coolant temp gages for liquid cooled engines. I've seen a few web sites with a limited selection of Acewell meters but all of them are for large motorcycles incorporating far more indicators than our scoots would need. Perhaps one of the dealers that come here might think about applying to Acewell to carry their product line. .acewell-meter.com/" rel="nofollow" target="_blank">.acewell-meter.com/You can download the manuals for all their meters at the link above.

Body work

You would think dealers would sell complete body replacement kits and hardware. Considering body panels are common across many brands and even engine sizes this should be profitable. This is done for the big sport bikes so why not our scoots? After a couple of years of daily riding and sitting out in the sun in the parking lot and a bump or two from doors they start looking ragged. Lets not talk about dropping it on it's side. It would be nice to receive a complete body kit with matching paint and a collection of decals you can apply (or not : .

I put 60,000 miles on my first Chinese scoot. The ignition sensor went bad so it just quit running. It had started using oil and was showing a little blue smoke out the exhaust. The body panels were ragged and needed to be replaced. The radiator had developed tiny leaks around the solder joints. The dash needed replacing too as the speedometer had become erratic. The seat had a bad case of ugly too. After calculating the costs of a total rebuild I determined it would cost less to just order a new scoot, which I did. If you service your scoot and take proper care of it you should be able to do the same. BTY, I never used synthetic oil. I used Rotella 15w40 diesel engine oil. Just before it quit and I started parting it out the oil showing on the dip stick at every 200 mile fuel fill up would be down by 3/4 so I would top it off. When it was new It would be down by half on the dip stick at the 1,000 mile oil change.

I've looked at MRP parts before but never attempted to order any. They never had stock weight rollers or sliders or stock anything, just 'racing' parts. I used my scoot for basic transportation and not 'racing'. Why anyone would spend money modifying a scooter for higher performance when it would have cost less to just buy a bigger scoot. I like keeping things just the way they were designed to be. I put 60,000 miles on my first TANK 250 scoot before it needed a complete refresh which would have cost more than buying another new 250 scoot. I feel keeping everything stock helped me squeeze that many miles out of a cheap Chinese scoot. I was just about to roll over 14,000 miles when I was involved in an accident that totalled my second Chinese scoot. I was going to service the CVT variator, replace the belt, and clean the clutch as soon at the odometer rolled over 14,000. At the time I felt I had worked out all the bugs and was looking forward to putting at least 60,000 miles on it. On the plus side I saved enough money on gasoline alone to pay for the scoot as apposed to driving a car and I had a substantial reduction of insurance costs on the car due to reduced miles clocked on it. Then the insurance company of the person that hit me paid me $200 more than I originally paid for my new scoot. It looked like a Honda Reflex to the adjuster so he used the blue book value for it. In about 6 weeks I am going to order a new Linhai Aeolus 300. I want to order it now but I'm still suffering bruised ribs from the accident.

Yep! Windshield must come off and then the dash top cover. Nothing is easy on these scoots. I had to pull my dash completely out to fix a bad solder joint connected to the left low beam headlight. This required pulling the entire nose off it. The bad solder joint was where the single wire from the High/Low beam switch on the handlebar control split into two wires leading to the two head lights. That solder joint had become a resistor causing high current in the circuit blowing the low beam filament in the bulb. You might want to consider going ahead and cutting out these soldered joints and replace them with automotive compression butt connectors. You'll find the wire leading from the handlebar switches behind the dash. Just follow the wires connected to the headlight bulb connectors to the soldered joints.

The Chinese use soldered joints in wiring harnesses. When I was going through Basic Electricity and Electronics and Engineering Electronic Operation and Controls schools in the Navy we were told to never ever solder low voltage, high current electrical connections. I have found that soldered connections in automotive wiring will fail. When I purchased my first Chinese scoot (a TANK 250) I started having electrical problems after a few months. I found they had soldered some ground wires together inside the harness and this soldered connection had gone bad. I ended up pulling the wiring harness out, cutting it open, and cutting out every soldered connection and replacing them with crimp type automotive butt connectors. While I had the harness off the scoot I used marine grade water proof grease as a dialectic paste which is the same stuff sold as bulb and connector grease at much higher prices in all the connectors to seal them up preventing corrosion and oxidation. You can buy a tub of marine grade grease for less than a couple of packs of bulb and connector grease.

Hey n4zou that's a nice looking little set up? Wonder if a guy could make that work on just a plain non-digital scooter? JR It will work on anything. The Speedometer uses a magnet and sensor on the front wheel and it's programmable for tire size. The original speedometer cable is not used or required. Some indicators will be unused that could indicate some other function. The Neutral gear shift indicator can be hooked to the fan radiator switch so it turns on with the Radiator fan. The sensors for fuel level and coolant temp should work as well.

That metal scraping sound is caused by belt dust on the clutch pads. Rubber belt dust does collect on the pads which causes the clutch to grip more than it should. This puts too much pressure on the pad springs (not the main spring) causing that metal scraping sound you are hearing. The noise quits when the clutch is fully engaged with the clutch drum. Use a fine sand paper to lightly remove the little black rubber spots you'll find on the clutch pads and perhaps the clutch drum as well.
