- August 02, 2018, 20:34:40 PMQuote from: OR Seedman on July 28, 2018, 07:52:21 AMThis is my experience as well.......but that's not really the noise I am talking about. There is always a background "ticking" on both cylinders even after warm up...and there is a low "knocking" sound that I can hear behind the air box at idle....I have spent a lot of time working on automobile engines and it almost sounds like a rod knocking....almost but not quite...just weird. Doesn't seem to have any effect on performance...even at low speed and in high gear the bike still pulls like a mother...and when the engine rpms get slightly over idle, it seems to go away....
My ticking has gotten worse as the bike ages. Like I mentioned before, at this point, my theory is I have something wrong with the KACR unit. Have to pull the motor to take a look at this so not currently high on my list of priorities.
The 'knocking' (which as you mentioned sounds like a rod bearing) didn't used to be there but is there now - after a lot of research - could be something goofy with the vibration dampers which other 1500 owners have had problems with) I've got a new set of damper rubbers to go in but have been too busy with other bikes to get around to it.

- August 02, 2018, 09:53:24 AMEngine sounds just like mine, I have aftermarket pipes so they are a little louder but nice to know that other engines sound the same like marbles bouncing around in there!

- July 30, 2018, 21:05:13 PMmine might be a little louder than yours, but not much..I do have the aftermarket Thunder Air System, which seems to let some engine noise through, especially under acceleration ..I only had the 800 to compare it against, and the 1500 engine is way louder...Until I put the Roadburner exhaust on it, you could hardly tell the 800 was even running.....really a quiet engine....

and here is video when engine is warm:
I leave this what it is and I don't open my engine.

- July 28, 2018, 19:26:07 PMI notice little noise at start up but I am wearing ear plugs. Do any of you guys use earplugs? I do. How often do you change the oil? Because, how clean the oil channels in the lifters are, could mean that the valves aren't getting enough oil. I just did a ride and the bike worked flawlessly from 75deg to 110deg (air temperature that is). And this motor is one of the quietest motors that I have ever had. I am working on my old Moto Guzzi and that has opposing cylinders set up in a transverse fashion with solid lifters. The bike is great but it is very noisy when cold. After it warms up it is a lot quieter...

- July 28, 2018, 18:13:58 PMticking from the hydraulic units...common problem. http://www.vulcangadgets.com/files/newbie.html#expect
noises from the bottom end when the idle is too low..also normal. Mine ticks on and off when hot, and always from one rear hydraulic when the temps are below 70 degrees when I start it....It is, as the others have said, the way it is. As far as longevity, well...how's this?

- July 28, 2018, 12:20:42 PMwell...of it does crap out on me, I am only into it about $2k total with all the stuff I added to it...so I will just get another motor (maybe a 1600) and slide that in....other than the noise, it runs really strong, no oil burning or smoke and after 5k oil change (using Rotella synthetic) it still looks good and is quite clean....flushed the motor and nothing in the pre-filter screen either...So I'll take your advice since I practically did steal it...LOL

- July 28, 2018, 08:31:55 AMI have the same noises. The light "ticking" (HLAs) seems to go away after warm up. The "knocking" seems to be noticeable only at lower idle RPMs. I have the stock exhaust so I can hear the noises quite clearly. I don't worry about the noises and just accept it as the "nature if the beast. As they say..."ride it like you stole it" and enjoy it.

- July 28, 2018, 07:52:21 AMI can hear the idle soleniods at start up quite clearly as I have a Thunder tear drop air box with a K&N filter....but that's not really the noise I am talking about. There is always a background "ticking" on both cylinders even after warm up...and there is a low "knocking" sound that I can hear behind the air box at idle....I have spent a lot of time working on automobile engines and it almost sounds like a rod knocking....almost but not quite...just weird. Doesn't seem to have any effect on performance...even at low speed and in high gear the bike still pulls like a mother...and when the engine rpms get slightly over idle, it seems to go away....
Having had both models (800 and 1500), I have to say the for someone my size, the 1500 performance far exceeds the 800 in terms of low end grunt, hill climbing and passing ease. Still handles a bit like a tank in traffic compared to the smaller model, but that, to me, is a minor trade-off...
I just worry that the noise indicates I could be out on a nice long ride and my engine is going to take a major dump on me....I just don't know how well the previous owner took care of the maintenance....

- July 27, 2018, 16:17:52 PMThe idle solenoids are in the right side airbox. They shut off after the engine has run a bit and started to warm up

- July 27, 2018, 09:39:01 AMQuote from: chief on July 22, 2018, 11:30:10 AMHmm, good point. I think about it that solenoids is the point, because sound is comingthe cold idle solenoids make a racket. Many remove them as part of an airbox mod.
from the left side of the bike, near airbox.
Then if solenoids make these noises, is it dangerous to the bike?

- July 20, 2018, 08:38:37 AMThe more I listen to mine when cold the more I think it's coming from the piston skirts slapping in the cylinders. When the pistons warm up, they expand, reducing the clearance between the skirts and the cylinder walls. It's not unusual for pistons to be machined slightly out of round by design. Once warmed, they expand to a round shape. Normal oil film on the cylinder walls acts as a cushion and prevents wear and damage. It seems to take about a minute for the noise to diminish to an 'acceptable' level. I've gotten used to it and have learned to love the sound as unique and as a sign that I'm about to get out on the open road.
