Question about Motorcycles
My bike will not start any more when i first started it, it when first kick and the choke was high so revs where real high i turned the choke let it idol for a while then turned it off when i finished putting on the guards i tried to start it again but would not kick over when this happened there was not much gas in the tank so i topped it up but still wont start please help..
The NSR is a 2 stroke, so it needs 2 stroke oil as well as petrol. This is the reason they are known as "Stinkwheels". If the engine is run without oil in the mix it will seize. As the oil provides lubrication to the moving parts. You should also check the spark plugs are clean, they can oil up in a 2 stroke, especially if the engine is used a lot at low revs.

This to me sounds like you need a carb cleaning. If you have let the bike sit for an extended time the carberators maybe clogged or gummed up. This has to do with the new gas that is out there now. It is cheap and with the introduction of Ethanol alcohol now it is even worse on being stable for long periods of time. I have seen fuel go bad in as little as 3 weeks.. One quick check you can do is open you fuel tank and smell the fuel. IF it smells like varnish it is probably bad. You can drain the tank and add new fuel and that should solve your problem. Keep in mind, that the carbs need to be drained as well to get the old fuel out of there also. Make sure you have a battery charger going when you start crankin that puppy, because you will need lots of extra juice to get that baby to fire up. If it is starting now and runs on choke, that means your idle jets are clogged. Best repair is to remove carbs and clean idle jet. Unless it is fuel injected.
Let me know how that goes and we can proceed from this point. I am a certified mechanic from MMI as well as a HDTV GURU. Smiles. have a good one.

i'd start with removing the carbs and giving them a thorough cleaning as when bikes sit for so long, the carbs begin to get gummy/varnished from the old gas.
check for blocked holes in the pilot jet & main jet and look for "hard & dried up" gas in passages. be careful of the float bowl gasket as to not tear it or you will need a replacement.

SOURCE: kick start is jammed
Put the bike in 3rd, 4th or 5th gear, the higher the better. Sit on the bike, with your hand off the clutch lever, and rock the bike back and forth to rotate the clutch hub. This might free up the lever. You will need to drain the oil and remove the right side casing to see and service the kick starter. If I recall correctly, there is a spring clip that allows the kick gear to engage the clutch hub. The piece could be broken, weak or out of position.
Please rate this answer. Thanks Shay!

G'day egdbcs . Ok.now lets see.You say good spark,so i'm presuming you are doing the old sight test.Try bending the arm on a know good sparkplug about 5-6mm,earth the plug and kick'er in the guts(crank it over)Be very carefull , high voltage danger.If there's still a good spark it's safe to say that there will also be a good spark under pressure in the combustion chamber,speaking of which you should also do a compression test,anything over 100psi should be ok. as i'm not to sure of the extent of the re-build,hopefully the valves were lapped and checked for straight and true and valve seals replaced,if you notice oil on the tip of the spark plug you could have a leaking valve seal or oil seal .Try putting a small amount of fuel directly into the combustion chamber ,tighten up the spark plug ,install the plug cap and.......Yeah ..You guessed it ..."kicker in the guts".If all the abouve are correct and true it should fire up.If it runs for 5-10 seconds then stops you've got some sort of fuel starvation problem , could be dirt in the carb,blocked idle jet ,or air passage or even the needle could have come off it's clip,believe me with an old bike like yours anything could be worn and loose inside that carby.The only other thing to consider is the timing.There may be a good spark but is it happening at the right time inside the engine???. I'll leave it all in your capable hands EGDBCS.Hope this helps to solving your worries. Chow for now......Tilleydog..

Pull the slide out of the throat of the carb then move the clip at the top of the needle down one notch, two if needed. This will richen the low end fuel mix.
Need a "very helpful" rating asap. Thanks!
