I have a 2001 vz800 marauder that just bought with 2400 miles. The engine has this loud, random pinging sound in it. Inconsistent and only noticeable with throttle open a bit. Any ideas?

Sounds to me like a very common problem has occured to your neighbor. If this is a SOHC engine, one of the valve seats in the number 4 cylinder has fallen out. I'm sure it has damaged the head and the piston. Stop trying to run it or you might blow a hole in the cylinder wall or break a rod or both.

FORK OIL
• Place the front fork vertically without spring.
• Compress it fully.
• Pour specified front fork oil up to the top level of the outer
tube.

or an equivalent fork oil

more until no more bubbles come out from the oil.

NOTE:
Refill front fork oil up to the top of the outer tube so that bubbles
are visible while bleeding air.
• Refill specified front fork oil up to the top level of the outer
tube again. Move the outer tube up and down several strokes
until no more bubbles come out from the oil.
• Keep the front fork vertically and wait 5 – 6 minutes.
NOTE:
* Always keep oil level over the cartridge top end, or air may
enter the cartridge during this procedure.
* Take extreme care so as to pump out air completely.
• Hold the front fork vertically and adjust fork oil level with the
special tool.
NOTE:
When adjusting the fork oil level, compress the outer tube fully
without the fork spring.

Sounds like valve clatter, a common issue. We chased the same noise, with HD installing new push rods, adjustable rods and then they said it is a Harley. Not a real answer. This noise ruines the ride as it grabs your mind and focuses you on the noise.We tried different rod extensions within the lifter adjustment range, same deal. We chased for about 1 1/2 years, trying to not void warranty.

The only long term solution was to go to aftermarket (velvet touch) lifters and lifter blocks. Now we NEVER hear the issue.
