Classic valve train issues. Sounds like the valves are tight. One thing that concerns me is the "sudden onset". Valves usually tighten over time.
Make sure you also tighten the cam chain as well.

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.

Please rate this solution as "FixYa" if I have answered your questions. Thanks!

SOURCE: dead pw 50 and sad boy.

Many things could cause the problem. Let me see if I can help out.
You have spark, but is it enough spark? A weak battery can rob power from the coil so only a weak spark is present. Get a new stock NGK spark plug to eliminate the possibility of a problem plug.

It is good that you cleaned the carb because that would be my second target. Reset the air and idle screws. IMPORTANT > do not tighten these two screws down. Only screw these in until they LIGHTLY seat. Now turn each screw one and one half turns outward. Clean or replace the air filter and be sure the bolts are tight on the carb manifold. INSTALL AN IN-LINE FUEL FILTER. Let the float bowl fill then start the engine. Set the idle speed with the idle screw.

Remove the cylinder head. run the piston down to the bottom of the cylinder. look inside the cylinder. On th carb side (intake) you will see an intake port > a large hole that lets gas into the cylinder. Now look at the exhaust port. It is possible the exhaust port is pretty plugged up with carbon. The intake and exhaust ports should be approximately the same size. Are they? If not then remove the muffler and take a screw driver and plastic hammer and knock the carbon into the cylinder, thus enlarging the exhaust port to its' proper size and allowing the exhaust gases to escape. Vacuum the carbon out of the cylinder. De-carbon the piston top and the cylinder head.

Get back to me and tell me what you find. If more is needed we will go further.

Suzuki jr80 takes too long for rpm to get back down to idle , after throttle is released. wasnt run for couple yrs. completely disassembled carb and cleaned. it starts 1-2kicks.not setting correctly?


Hi, Troy and the usual suspects are:
1. Throttle cables improperly adjusted, pinched or need lubrication.
2. Idle adjusting screw needs to be backed off.
4. Air fuel mixture adjusted too lean start with 2 full turns.
5. Intake system air leak.
6. Fast idle choke ramp is not releasing.
7. Broken throttle return spring.
8. Damaged diaphragm or slide.
9. Faulty MAP, TPS, ATS, O2, sensors or wiring/connector

Rm 250 starting issues


This may help you determine the problem.
1. is sprkplug oil fouled? wet? dry? superhot and white electrode?
A sparkplug will always tell you whats going on.
if its too wet then its not burning all the fuel and oil and flooding out.
if its extremely hot and white, then its running lean , and needs more fuel.
also make sure your running 50:1 fuel oil mix.
a hot two stroke is hard to start.
if plug is dry, then its not getting enough fuel.

2. make sure your fuel oil mixture is 50:1.
to much oil is okay but it may smoke alot
way to much oil will oil foul the plug and plug will have oil on it.
to little oil will make the bike run hot and start damaging the bottom end crank bearings as well as your rings , then piston and cylinder walls.
the plug will be whitish and hot.

3. as for the timing , the rotor is resting on a keyway on the crankshaft and will only move out of time if the keyway is sheared.

4. make sure you have good spark when bike wont start.
a coil that is going bad will work cold but may not when it gets warmed up

to sum it up check to make sure you have correct fuel mixture
check you sparkplug to see how its burning
make sure you have good spark

if you have good spark, good fuel, good compression, then it should start within 2 kicks everytime.
i have a blaster 2 stoke 4 wheeler, starts everytimesince i rebuilt it.
i hope this helps you out and you can enjoy the rest of the summer with your dirtbike.
best regards

Yes i have a 1982 suzuki gs650 i am fixing up . i put the key in the ignition and it wont turn so i was wondering how i can start it to see if it is worth fixing


Hi , start by putting the byke on its central stand or other device, in order to get rear wheel on the air
engage on 4th or 5th gear and try turn the engine by turning the wheel (better without sparkplugs)
if it turns ok without noticeble strange noises, then put the sparkplug back and try ( ask a friend for help) to push it dow the road in 2nd gear
at this point i'm assuming that everything else has been checked (petrol, spark oil level,etc)
good luck,

My 2002 suzuki tl 1000 is not starting and the battery its good what could it be. when i turn the ignition nothing turn on i check the the relay an fuses and ther good


Check the ignition coil unit to start with. Is the spark blue or orange? Take sparkplug out,..put on plug cap...touch bottom edge of plug onto metal..[cyl. head], turn bike over...and check for spark color. If spark is "orange",..the coil is shot...replace it.

Motorcycle/dirtbike/ttr225/starting problem. Is not getting gas to sparkplug.As long as i put gas in sparkplug hole motor fires until burns gas out.


sounds like your pilot jet may be clogged, or your needle valve is stuck shut, remove the float bowl and check it out. (the pilot jet will be the smallest one, and the needle vavle will be attached to the plastic float assembly.
