Either the big end- or the top end bearings are almost dead. I've seen this on many bikes including my own GSXR. It's not really something you should attemt to fix yourself, it's a massive job. Rather take it to a shop, and let them check it out for you... Hope that helps

Engine starts and idles but has a loud slapping noise.No smoking from exhaust has good oil pressure any help or suggestions what it might be and approximate cost of repair.Thanks

Hi Mike:
What kind of bike and how old? Vintage Harleys sound like that most of the time. Just kidding all you Harley guys & gals!
Mike, can you tell where the sound is coming from, and most important, what happened immediately before this noise started?
If it was from the engine, I would not run it until I had it figured out.

Any ideas ?

There is a problem with the starter solenoid or the starter teeth aren't syncing properly with the engine. With such low mileage, I can only assume the starter has been used when the engine was running.

Pings at any timing adjustment not using cheap gas 96 in stroker

If you're running a 96 in stroker, you're probably running a hot cam as well. In this instance, I'd set the front cylinder advanced timing to no more than 33° maximum advance. Somewhere between 30° and 33° is where I'd set it. Also, if you're running over a 9.5 to 1 compression ratio, I'd run some sort of fuel additive even in high octane pump fuel. The fuel we have today is lousy, not like it used to be years ago. I just built an 89 in, stroker with a 3 Suns cam, Head-Quarter's modified heads, and 10:1 compression. It dynos out at a 98 HP with 95 FT. Lbs of torque. We have to mix the fuel half and half high test gasoline and 101 octane racing fuel to prevent pinging. If you're running an aftermarket ignition system, make sure you don't have your "rate of advance" switch set to advance your timing too quickly. To set this, start at the slowest rate of advance setting on the ignition system. Ride the bike and see if it spark knocks. Advance the setting one notch at the time until you get spark knock and then go back to the highest setting in which you didn't get any knock. Do not confuse intake noise with spark knock. I know it sounds silly but I had a guy drive me nuts doing that once. When he'd open the throttle, he'd hear the intake noise and thought it was spark knock. The clue came when he said that it spark knocked even at idle. Do What? Then I knew what he was hearing. The long overlay grind of the cam was making a noise that he was hearing coming out of the intake. LOL. So, ****** the timing a couple of degrees off of maximum, boost your octane, and make sure your rate of advance is not too quick. If you have an igniton system and don't have the instructions, go to their manufacturers website. Usually you can download and print out the installation and setup instructions.

Good Luck

I have a 2008 v-star custom 650, when i just turn on the key theirs a click noise jusr under the front side of the tank, what is that other then that it rund and rides great.

Pretty sure your bike has a fuel pump to assist getting fuel to carbs.....very typical to hear the pump click a few times to refill carbs prior to startup....once the carbs fill it stops till the carbs use some fuel......actual the fuel pump is clicking away as needed when the bike is just can no longer hear it over the engine noise.

2002 hd fat boy 1450 kiryakin air filter vince hines 2in1 pipe 16000km my problems is on the left side on both top valve cover theres a clicking noise coming from there more likely when the engine warms up...

What you're hearing is the rocker arm opening the valves. This is normal operating noise.

Your Harley is an older design pushrod operated engine. Unlike most other motorcycles engines, Harley does not use overhead cams in any of their bikes other than the V-Rod. Additionally, there is no sound deadening material inside the rocker box covers. Although the engine is equipped with hydraulic tappets, there is a bit of running clearance in the rocker arms and their shafts they run on.

In short, this is not unusual and your Harley will run for many miles. If you can hear that clicking, it sounds like you need to take the baffles out of that V&H pipe.

To see a diagram of your engine, go to , click on OEM and choose your bike or any Big Twin of that year.

Good Luck

I have a brand new relay yet my fuel pump will not respond on my 1998 Honda NT 650. ANY SUGGESTIONS? Thanks.

Are you sure it doesnt respond? i thought the same and even bought a new one still no change.
I found out the if you empty the pump of fuel and the line leading in that you"ll hear it over the engine noise as a slight clicking noise till it gets full and quiets down. also i took on of the line off just to make sure the gas was being pumped out when it was quiet.

Rattling Engine noise in idling conditions also.

That could very well be the case.

You could have some bad piston slap problems. Not uncommon to those models

Engine Sound

It is normal. Nothing to worry about. What you're hearing is the sound of the output shaft rotating and meshing with the clutch mechanism.

Starting problem

The clicking noise you hear is the starter solenoid that switches power to the starter motor. The fact it is clicking indicates that everything up to the solenoid is working. A few things to check
  1. be sure that all connections to the battery and earth to the chassis are secure and free from corrosion
  2. check the terminations at the solenoid and starter motor to be sure that that they are ok. 
  3. If you can meter 12 volts getting to the starter, would point to the starter failing. May need the brushes replaced. 
To help you troubleshoot the problem, here is a Service Manual for the bike you can download for free. Just enter the 3 letters as requested at the top of the screen.  Happy to talk to you more about the problem. Thanks for using FixYa. Hope you get is sorted out.
