Question about Suzuki Motorcycles
Posted by Anonymous on
The TS 125 was a great little engine and although not the most basic of 2-stroke designs, they aren't the most complex by a long way.
I suggest you try and find a repair manual so you can do your best for what was a great little bike.
The fact it is firing when you introduce fuel into the combustion chamber indicates the engine has upper compression and the ignition system is producing a spark at approximately the right time so there are three things on the list of requirements ticked off.
What it obviously doesn't have is induction drawing fuel from the carb and delivering it to the combustion chamber. If the fuel tank, filter, fuel tap and fuel line is ok, the fuel fresh and the carb clean then induction must be possible so if it isn't happening it is likely something is wrong in the crankcase preventing crankcase compression and a good and strong induction pulse - perhaps the crankshaft seals are perished or defective in some way?

Hi, Anonymous and the usual suspects are:
1. Fuel tank empty.
2. The fuel tank has old dead gas.
3. Fuel tank bottom contaminated with ethanol sludge, dirt, water, rust, etc.
4. Fuel supply valve/petcock turned off.
5. Fouled spark plugs.
6. Engine flooded as a result of overuse of the enrichner.
7. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
8. Fuel valve/petcock or filter clogged.
9. Fuel line to carburetor or throttle body pinched, kinked or blocked.
10. Carburetor float stuck.
11. Fuel injectors clogged.
12. A severely discharged or damaged battery, you need 12.5 volts or better and be able to pass a load test if necessary.
13. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
14. Loose or corroded wire connection at the coil or plug between ignition sensor and ECM module.
15. Spark plug cables in bad condition and shorting check for spark leakage in the dark, cable connections loose, or connected to the wrong cylinders.
16. Ignition timing incorrect due to a faulty ignition coil, ignition module or MAP, CMP, CKP, O2, TPS, ETP, IAC sensors.
17. Faulty neutral, clutch lever, or kickstand safety switch.
18. Faulty fuel pump or fuse or relay.
19. A stuck bent or burnt valve.
20. Tilt sensor needs a reset.
21. Security system not disarming alarm needs a reset.
22. Check for engine trouble codes.

Clogged Catalytic Converter. What happens is as you push down harder on the accelerator you force more gas into the system causing a slightly richer mixture and more exhaust flow is neccessary. The easiest way to look for a clogged cat is when it's dark out take it for a ride causing it perform it's problem look under the vehicle if the cat is literally glowing red hot you either have a clogged cat or an extremely rich fuel mixture.

Clean the air filter and, if you have one, remove the water trap bowl on the fuel petcock and clean it. How good is the battery? Install new STOCK plugs. Bear in mind it may be time for carb kits. Other than your cleaning the carbs, the carb kits and balancing and synchronizing of the carbs are best left for the shop to do.
Check the exhaust pipes. If there is a restriction in the burned gases exiting the tailpipe then the bike will not run right, will loose power and even die if too much back pressure builds up. Disconnect the exhaust system and tick off the neighbors with a quick ride around the block without a muffler. If the engine still dies then exhaust is not likely to be the problem.
Check the compression on all cylinders. Depending on the compression, the bike may be ready for a valve job. If you pull the head for the valve job then you might as well consider re-boring the cylinders and install new pistons and rings. Bear in mind, doing a valve job and / or pistons is not recommended for the novice. The good part is that when the work is finished you will effectively have a new engine.

did this just start all of a sudden or after being stored for a while? if it was stored then try new fuel, check and change fuel filter, and get some fuel system cleaner that goes in the gas tank, run til hot then let stand overnight. and try, old gas can gum up carbs starving the enging of fuel.

hi, each lead has the specific number on it. if you do this correctly then they genrally give you an idea to where the sit in the coils( the way they bend :-) ) also i believe the coils are better off been attached to the frame once you are sure leads are in corect order and possitioned correctly in the coils.i just presumed the coils neaded earthing. make sure battery is pleny charged as a bad battery can just hinder. it is also very easy to flood the bike so just check the plugs again. if they are unusually wet then dry them off and try again . otherwise maybe try cleaning all electics.
hope this somehow helped
