How do I determine the size of the fork seals needed if I don't have the forks off the scooter? It's for a 2008 Tank 250 cc Linhai sport scooter.

Just a short update. After fiddling with a gunked up carb and a full re-clean she started, idled and didn't bog down with quick blips of the throttle. And for some reason the headlights will now respond to the dim/bright switch. Need to reassemble the under-seat box and the seat then it's off for a test ride with a 2-years expired tag! LOL

Well, I pulled the carb and it needed a good cleaning again. The float was sticking due to a little gunk buildup. I thoroughly cleaned the carb, reinstalled it and after multiple attempts she finally started and idled. I also tested half throttle to make sure there was no bogging down and for the first time in a long time she runs just fine. I'll road test it once I get the under-seat compartment and seat reinstalled. Thanks for the help.

You might be right about the float needle. I didn't think of that. Thanks for the tip.

The history on this 260Tank is that it sat for quite some time (3 years). It was in the shop a month ago and after some work on the carb the scoot started and ran just fine. This was after I tracked down and repaired an electrical problem caused by mice. When I got it home I discovered that it wouldn't start and found a cracked intake manifold. I replaced the manifold with a new one. Now, it started and idled for 10 seconds before shutting down. Upon a second attempt to start it I saw fuel flowing out of a side port on the carb. I'm no mechanical expert but I know enough to think this ain't good LOL. I deleted the stock airbox and installed a carb filter, much like the ones I used on my older bikes. What should be looking for as a cause here?

Yes. I had to remove ALL plastic to chase down the problems. And I get it about the light switch. Upon re-installing mine after inspection the lights will not turn off at the switch (not a problem) but they are in the bright mode and will not switch to dim. Thankfully the turn signals operate properly.

I also discovered why the engine bogged down when accelerating...cracked intake manifold. The tube running from the air box to the carb never did fit well and it is so stiff that it won't flex into place without pulling on the carb. I suspect my attempts to tighten the 2-piece air tube together and at the carb put pressure on the manifold and cracked it. So I'm foregoing the air box and installing a filter at the carb. Yes, there's a risk of water getting into the carb but I'm not a daily driver on this scoot. Besides I've had several motorcycles with carb-mounted air filters and never had a problem. Once I reveive the new manifold and install the rest of the body parts I'll be back on the road...finally...after 5+ years. Yes, this is a 2008 model with only 422 miles on it.

Found a loose ground connector in the headlight harness plug.

These Chinese scooters are a constant challenge. It is now running after installing a new carb kit and adjusting the idle. But the headlights will not come on. If I use the flash switch on the left hand control the lights will flash on. But the primary light switch will not turn on the headlights. I pulled apart the switch and the contacts look good with very good solder connections. I checked the wiring and there is no "mouse" damage to it. The switch might be bad...don't know. I'll put a meter to it later today and see if I can locate the problem.

Well, after removing the old fuel, replacing the fuel lines, filter and the fuel pump it will not start. Cranking is strong, carb is getting fuel and I have spark. After playing with this thing for so long I finally gave in and took it to a shop that works on these Chinese conundrums. Hope to find out the cause and get it back on the road after not using it for 3 years.

I finally decided to pull every body panel off of the scooter and do a full inspection. Lo and behold, after removing the faring I found a large mouse nest. Upon close inspection I found one wire had been fully chewed through and a second one with the insulation chewed off. These 2 wires rest right above cross member of the fork. I spliced them both. I suspect that when the scooter was brough down off the center stand, these 2 wires came into contact with the fork. Both wires come off the main harness and go into the fuse box. (no blown fuses) Now I am clearing out all the old fuel, replacing the fuel lines and filters...and cleaning the carb. Once I finish up the carb I'll hook up the battery and see what happens.

As I thought...a second look revealed no side stand switch and the center stand, when in the up position, comes nowhere near a harness. I guess I'll have to check connections and circuits associated with engine electronics.

I looked for a side stand switch and didn't see one. I'l have to look for a harness that comes in contact near the center stand.

At least I think it's electrical. While on the center stand the engine fires right up and runs. As soon as I drop the scooter to the ground it dies. And it won't start with the wheels on the ground. Any ideas of where I should be looking?

As for the muffler I checked the air flow and it was strong. But I'll take a close look.
