If this is when you are riding, then I would suspect that the ignition coils are breaking down, or you have blocked main jets in your carbs. Try changing the coils first and blowing through your jets with an airline..

Sounds like the engine is down on compression. Probably needs valve adjustment. If you have the tools, or can borrow them, do a compression test on both cylinders. Or if possible, a leak down test would give you an even better idea of what is going on inside that engine. Good Luck!

can you help me

Apparently this is a common problem that I also have. Another website said that there is not a true reserve. This bike is designed to slow down the fuel pump when the reserve switch is on the "on" position and the fuel is low to give you the sense that you are running out of gas. My solution, reset the trip meter each time you get gas and make sure you fill up before reaching 100 miles.

check throtle cable is routed properly and make sure cable is lubricated

I am not real familiar with you bike but I may be able to help you trouble shoot it. Is the motor trying to turn over? If not it may be your starter. You should be able to tell by the sound. If its sounds normal starting up but wont turn on. You want to check and see if your spark plugs are good. Take them out and touch the threaded part of the spark plug to an unpainted piece of your bike. Now hit the start button and see if they spark. If they do not spark or have alot of carbon build up on them replace that and try again. If the new spark plugs do not work then its a wiring problem and let me know and I will talk you thru that. If its not the spark plugs then you want to check the gas flow. On the bottom of the gas tank there will be a shut off valve for the gas(petcock). Attached to the petcock there is a hose that comes off the bottom and runs to the carburetor. Turn the petcock off and detach the hose from the carburetor. Get a basin that you can temporarily put gas into. Put the hose in the basin and turn the gas back on. If you get good gas flow the petcock is good. Now if they are good this is where the fun begins. The carburetor is very touchy when it comes to any dirt or anything of that nature there are alot of small holes for the gas to go thru especially with the main and pilot jets. It may just be that the float is stuck. Your best bet in this case is just to get a phish(its like a parts schematic) and a bottle of carb cleaner and go to town cleaning all the ports and pieces. Make sure that when you take the carburetor off you put a clean paper towel in any open holes in the motor. You dont want any dust or dirt getting in there.

there are 2 carbs--where the cable hooks to them theres a spring lever that hits a screw-u ajust that by ear with bike runnin----------buy a clymer book for total repair

check the neutral(ground) and look at the other wire too , could be just a bad connection. failing that check the bulb holder itself. you say the bulb is ok? sometimes they look good but are duff try it in the front where you know it should work.

Wot bike

I would start simply.Check or replace all your bulbs first.Then take apart your bulb sockets front and back and spray with electrical contact cleaner and a little lubricant.Make sure all the sockets have free travel and are not corroded at the grounding points on the frame.Some lights ground through the frame mounting and some have a separate ground wire.It sounds like you may just have a bad connection. Most brake lights wont work with key off as there is no power to the circuit.Also clean your brake light switches in the handlebar and down on the frame for the back brake.

either your float has got stuck so that the petrol flow into your carburettors does not stop or the needle and seat is stuck or worn, You might have also changed the float level adjustment. remove the carbs and open the bowls to check.

Sounds normal, overheating engines will cause the exhaust header to glow red, and the engine will begin running bad.
Make certain the oil is changed regularly and checked often

most gas now has ethenol in it try adding stp octane boost to the gas and it will evaporate the ethenol

Two things
1) you do not have the transfer case bolts tight enough meaning that you are not setting them to torque specs.
2) Most likely - You have a leak somewhere else that you are thinking is coming from the transfer case. I would remove all the excess oil from the motor by cleaning it with some type of degreaser and then checking to see exactly where the leak is originating from.Most of the time with motorcycles due to the fact that the engine is getting so much air when riding, your leak will tend to travel making you think that a leak is somewhere else rather then where it is really at.

When you say blue smoke, I assume you're meaning oil burning. Is there a characteristic oil burning smell to the smoke? Have you checked the compression? The blue smoke sounds like it could be caused by sticking rings. I personally never store a bike completely dry. I would change the oil before storage, fog the cylinders or run an ounce or two of oil through them with the plugs out, replace the plugs and, depending upon the anticipated duration of storage, either fill the tank with stabilizer and Marvel Mystery oil added to the fuel or drain the tank. A more likely scenario is that the smoke you're seeing is caused by carburetor floats not rising enough to keep the fuel in the bowl at the correct level. As far as the fuses blowing, you will need to isolate each circuit and trace it through. It's possible your wiring could have been chewed up by mice.

Your float is set too high. If you have the service manual, check to see where it should be set. You will need to remove the float bowl and generally there is a metal tab that will need to be bent in one direction or the other to adjust the float height. It coulf also be debris in the needle valve keeping it from closing completely. In either case the float bowl needs to come off. Safe riding.

Below is a diagram. Turn the air screw inward until it lightly seats then open it up two turns. Set the idle speed with the throttle screw. The throttle screw pushes against a lever on the outside of the carb. From there, adjust the air screw for best idle speed. Do this for both carbs. Be sure the air cleaner is clean.

check if there is crack of your spark plug cap

make sure there is no high point in the brake line and the master cylnder end bolt points down. some times need to turn the handle bars or lean the bike, and occasionally remove the master cylnder off the bars to get fall all the way to the wheel caliper, and keep bleeding
