Sound like the carb is fowled, add some fuel stabilizer to gas like - STA-BIL (find at any autoparts store). Add according to directions, this will help break down any deposits and waxes that form in the ports (& jets) of carb. allow a good hour ride to notice a difference. Then store bike with fresh gas and STA-BIL. Works most everytime. Prost! Ps: Much cheaper than rebuilding carbs too!.

SOURCE: Grinding sound from engine at idle and under low rpm load and gets quiet around 3800rpm

The crank bearings are probably trying to tell you something. How much oil is in the gearbox? When was the last oil and oil filter change? Anytime you hear a grinding something is seriously wrong. Change oil and look for metal in the oil. Also run a magnet through the oil.

SOURCE: Duke 2 loss of power when engine under load

Is the bike at stock condition?
Check the carb and the charging system.
You should measure 13,5-14V at your battery in 3000rpm with your high beams on.

My Vw at low revs under load in 4th 5th and 6th have a Jerk when I floor it. If anyone can assist? Thanks


What do you mean by low revs?

Under 1.5k rpm, the engine will not be generating enough torque in those gears.

Gear changes should occur between 2.5k and 3k rpm for a smoother transition.

How to stop the transmission noise in 5th gear on a 2007 HD Ultra Classic?


The 5th gear noise with the 6 speed is legendary!

1st and 5th are straight cut gears. 2nd,3rd,4th, and 6th are helical cut gears. Straight cut are stronger so Harley put them in the most popular gears.

Some people swear that either Mobil Syn 75/90 or Redline Shockproof 85/140 helps.

Baker transmissions make a F6F kit that has a helical cut gear, and a thicker trapdoor to handle the increased side loading because of it, but it ain't cheap!

Big twins can put a lot of stress on the spark plugs when under compression. You may also have a failing ignition coil, or a loose earth on your ignition system.

There is a fault in the alternator Probably worn brushes or damaged slip rings that are not keeping good contact under revs. Could even be oil on the armature causing the problem

2005 HD Ultra vibration at idle


Hi Vernon, and the usual suspects are:
1. Wheels and or tires unbalanced, worn or damaged.
2. Engine/transmission/vehicle not aligned properly.
3. Primary chain badly worn or links tight as a result of insufficient lubrication or misalignment.
4. Engine to transmission mounting bolts loose.
5. Upper engine mounting bracket loose.
6. Ignition timing incorrect/poorly tuned engine
7. Internal engine problem/ flywheel shift runout should be .003" max.
8. Broken frame
Good luck

There's only two things that could possibly make contact with the top cover and cause any problem. One is the shifter pawl and the other is neutral switch.

The shifter pawl return springs are notorious for breaking in the five speed transmissions. I've replaced a load of them. Take your foot shifter pedal and lift up on it until the transmisson just tries to shift. Then go back to the center position and press the lever down until the transmission just tries to shift. Does the spring pressure feel the about the same in both directions. If not, the shifter pawl return spring is broken.

With the top off, you can inspect the small spring on the sfifter pawl itself. See if that spring is broken. This is about the only thing that I know of in a five speed that will cause shifting problems. But then, I never claimed to know it all.

Good Luck
Steve

My 2001 chevy blazer is misfiring and will not rev beyond 2000rpm without cutting out but it idles alright


trying to rev the engine in neutral will not work. the computer will limit the rpms.it is kind of a goofy safety measure built into the system. to diagnos the missfire you can remove one plug wire at a time with an insulated pliers.the missfireing one will -not-slow down the engine speed. if all cylinder are firing properly at idle and only misfires under load you will probably need some help have a driver put on the brake and accelerate a little untill it misses. when you have verifyed this try the same thing with the plug wires while it is missing. do not keep the engine torqed this way for more thn a couple of seconds. you could damage the trans.. when you locate the missing cylinder you will need to find out why it is missing. look at the spark plug,and maybe swap one plug wire for another to see if the missfire moves to another cylinder. i am assuming you have no test equipment. if that does not change,see if you can get at that injector for that cylinder and lightly tap on it with a metal punch.if problem seems to go away or engine misses when tapping injector it will need to be replaced.
