Does not sound like a Harley but possibly, probably you need new spark plugs

Check your spark plugs for damage at the electrodes; state of plug wires; coil and ground connections... Could also be lean air/fuel mix and/or low float level causing it to run lean.

2001 Toyota Tacoma keeps stalling on start up.


Check the battery cables. I had the same issues with my 96 tacoma, The battery cable connection at the battery can be cranked down but still be loose. Hard to explain, doesn't make sense, but just check it out.

Having problem when i try to accelerate engine starts to miss


First, if you increase the rpm's while the vehicle is idling, do they come up normally or does it miss then too? I would check to see not only if you have spark but what the spark intensity is. (under load, a weak spark can actually be extinguished) firing through the exhaust means that either you have a burned exhaust valve , badmoz-screenshot.png exhaust lobe on the cam or that the ignition timing is so far off that it is firing when the exhaust valves are open.If you have a 4.0 engine, it is possible that the outer ring on the crank pulley has turned and what you think is correct timing may be not even close.
