    is the choke ON or OFF when you try to rev the throttle?

    is the bike warmed up when you try to rev the throttle?

    if you let it just idle, will it continue to run as long as you don't touch the throttle?

    any fuel leaking out of the overflow tube onto the ground?

Go to www.2strokeworld.com and look up jetting charts for your bike find the best settings for your environment and riding and try those settings and see if the bike runs better
Note: jetting a 2 stroke is all trial and error and you probably go through quite a few spark plug before you get it locked in but once your jetting is just right it pretty much problem free (but you still have to do basic manteince though it that problem free - sorry) ;) oh one last thing if you DON'T have a service manual for your bike GET ONE!! because your going to need it

There's a couple things you can try, firstly make sure you've got the fuel to oil mix correct as too much oil in with the fuel is one of the most common reasons for this and also try a standard plug rather than a race plug as these can handle the oily residue a bit better. i would guess at the mix being around 40;1 but check with a honda dealer first. hope this helps

How old are the spark plugs and wires. GM vehicles are great runners until something goes wrong with the typical spark or fuel delivery issues. Wires or fouled plugs may not set off the computer, it will just run crappy.

Car runs for ten min then dies


Not sure what kind of car this is or year and etc, you will need to get the car to die and start with a couple of tests to see whats not working. next time it doesnt start, try spraying starting fluid into throtle and see if it starts and dies, if it does then we know its a fuel problem and may be fuelpump. if that doesnt make it start then remove a spark plug wire and place it near a metal object like the motor or a bracket and have someone try to start it and watch for sparks, if theres no spark then you may want to have the control module tested or the coil, hope this is helpful,

The only thing left is the cam lobe it self. Run all new plugs for just one week. Pull the plugs - laying them out each plug for each cylinder - -mark them. Change them to NEW again - in one week - pull them and compare them with the new plugs. Some times you just get back plugs too so if you want to short cut it - change the plugs say - that cylinder with number 3.
Also - how old is the timing chain? This happens a lot with stretched chains - That is an old engine so I would seriously consider the timing chain being stretched. Inspect it as a precaution. I would replace it if you do not remember when it was changed to the month and year.

The unit is lean. rebuild the carb with a carb kit and check your fuel lines. If they are brown or discolored or brittle they need to be replaced. carb kits run approx. 11 - 18 dollars from your local dealer.

Power failure


if the engine is dieing, check that the spark plug has a cap that is sealed eg rubber boot around it.
if the revs are still there but the bike slows the trans belt is getting water in it check the trans gasket for sealing.
