Question 98 Dyna Superglide tapping sound

Greetings All,

I've uploaded a video of me trying to explain the weird sound to a friend in Arabic... but i was thinking maybe you can hear it as well in the link
what do you think that tapping sound coming from the front side of the engine is related to?
how should i approach this?

Thank you for your help!

Rakan

Lifter or an adjustable pushrod that needs a little more preload (if it has adjustable pushrods). Mind you, that is a guess.

For starters I would pick up the idle to at least 950 rpm.. It's idling way to low. And as Nomadmax mentioned, pop your pushrod tubes to see if you have a loose adjustable pushrod. If you have the OEM pushrods, then I would suspect a bad lifter or lifters. DO you have a FSM and are you mechanically inclined? If not you better take it to a repair shop...

I dont know whats a FSM....I cant count on any repair shop here in Saudi (not even the dealership)... i have to do it myself.

so pushrods inspection and then lifters...
I'll order both and change them any ways... do i have to take the engine off of the frame to do that or not?

FSM=Factory Service Manual.. It'l walk you through the process of diagnosing a noisy valve train.. I suggest you do not touch the bike till you get one... They are still Available through the dealer.. And no you don't have to remove the motor.. Once you get your FSM come back and we'll help you through it...

rakanghoth,

Just a note of caution,

If you get to the point of removing rocker covers, remember to follow the service manual instructions absolutely to the letter, to avoid engine damage, especially on reassembly.

98hotrodfatboy can get you through this, he knows his stuff.

Get a clean work area, and some ziplock bags,

Don`t mix up lifters and pushrods, keep them organized so that they go back in the same location.
