Check to make sure there is no damage to any wiring. Check to make sure the magnet on the flywheel still has meagnetism Also make sure the ignition switch is not not the problem by spraying it down with contact cleaner on the electrical portion. It can corrode from sitting so long. If that does not work, Swap the ingition module./ignitor for a known good one- it is most likely that module failed.

Replace the spark plug caps and try again. On Honda's the cap is often part of the wire (a dealer part) NGK makes some inexpensive plug caps about $5 each. They should OHM out to 5000 anything above or below and you need to replace them. This should fix the problem.

SOURCE: 2003 honda crf230f will not worked fine

IF you have a battery get a new one ; put in new gas ; super; dsid you ajest any screws on carb. You tight need to run a prime tank right to your carb to prime it; and then hook your tank backup new gas lines to your carb. Now break out with the WD40 to spray all switches for rust.

SOURCE: i got a 1995 cr250 dirtbike and i have a problem

im thinking if it has spark and getting gas and has compression, the bike will run. sometimes a "WEAK" coil will give a good spark, but under compresion its not enough to ignite the fuel. if thats not the case, take the air filter off and spray starting fluid into the carb and with NO CHOKE, give it full throttle and kick it over. if that dont do it try compression starting it, tow it for some distance if you have to. if that dont do it, then there must be something wrong with the carb. jets, fuel air adjustment. thats all i have. good luck.

sounds like your coil is bad,could be few other things but coil is most common,and least expensive.if memory serves me right its mounted under tank( just follow plug wire to coil) will cost around $40.00 used and $80.00 new

How do i test the stater and coil on 1979 honda mr50 dirt bike

Have you replaced the condensor? Do the points actually spark?
Have you checked HT lead and plug cap? Remove cap and place bare end of ht lead on cylinder head so that spark can jump from core to cylinder fin, DON'T hold it there... Kick engine over and look for spark at end of HT lead

1979 Suzuki GS1000, cylinders 2 & 3 are not firing

Hi, Anonymous you need "FIVE" things in order for a cylinder to run properly:
1. FUEL: in order to validate your not getting fuel spray some starting fluid into the air cleaner and hit the starter button, if it fires up and runs for a few seconds then you know you have a fuel delivery issue. Multi carb banks should be bench "SYNC"
2. SPARK: remove the spark plug and with it connected to the spark plug cable ground the threads to something metal you should see a bluish white spark if not you have a faulty spark plug, spark plug cable, ignition coil, condenser, CKP, ECM, sensor or the wiring in between.
3. COMPRESSION: you must have at least 80-100 PSI for most bikes, multi-cylinder engines should be within 10-15% of each other if not perform a leak down test you may have a burnt or bent valve or hole in the piston or broken rings.
4. CAM TIMING: confirm your timing marks are aligned to see if the cam chain or adjuster are worn out and the chain has skipped a couple teeth.
5. IGNITION TIMING: on older bikes check to see if your points have not closed up, timing plate has not become loose and confirm with a timing light for proper retard and advance functions, on newer bikes where timing is controlled by an ECM and is nonadjustable check you CKP, TPS, MAP, O2, sensor or its counterpart for integrity.

Backfiring through the carb isn't a timing issue unless you're firing at BDC (180 degrees out).
or have bad/missing/cracked piston rings / hole in the piston.
I mean, correct me if I am wrong, but that thing IS a 2 stroke, right?

Xs750 what is the firing order

There is no firing order. Your bike has a coil that fires on both the compression stroke and the exhaust stroke (also called a wasted spark). Therefore either plug wire can go on either cylinder and the bike should run the same.On four cylinder bikes this meant that you could run four plugs using only two coils and two sets of points instead of four coils and four points.If the bike is running poorly try new spark plugs and new spark plug caps first(start with the cheap stuff). Next check the actual coil and pulse pick up or points. You may have to replace the coil only because the wires are cracked shorting.

You will need to do a compression test, check valve clearances. Check plug cap carefully for a crack and
occasionally a spark plug can fail under engine compression conditions, even when it looks ok testing it, you didnt mention if you fitted new plugs
