Could be coil, leads or plugs. On early models it could also be points. Later models with pointless ignition system problems tend to misfire in all rev ranges
If your testing this with the vehicle in park it won't go over 3000 rpms because the rev limiter kicks in so you don't do damage to the engine. If you are in drive and you step on it when it's safe to do so, it should go well over 3000 rpms.
maybe your rpms gauge is broken.get it looked at by a professional
major vacuum leak?
carbs need to be rebiult
You have a vacum leak. A big one. Check all your hoses. Idle should be under 1k rpms
igniter is possibility
Advertised Horsepower and torque is... HP-----245 @ 4000 RPMs Torque.......355 ft. LBS. @ 3000 RPMs
No no no, 3000-4000 rpms is the average speed for highway traveling, driving too close to the red mark on your rpm is bad
Put a filter in your exhaust to catch the smoke before anybody sees it. Err. get a new motor! lol
Obviously depends on RPMs. Normally 15-20psi at idle. Could be as high as 30-40psi when the engine is under high RPMs.
3000 rpm means that the engine is doing 3000 revolutions per minute. In a lower gear at the same speed the engine would be doing more revolutions per minute.
Stock Harleys come out of the showroom with fitted with a rev limiter that cuts the ignition out at around 5600 rpms. Gets kinda scary when you overtake a truck and halfway there the motor starts to cut out. Can be overcome by fitting an aftermarket ignition module that will rev out to about 7000 rpms.(more than enough for a harley)
