08 Gl1800 Engine rattle maybe HELP

[Bare]

Hi All
It beats me.......
It sounds like a flat metal washer vibrating on metal.
At 40-43 mph in fourth gear in 5th gear at 50-53 mph you can hear it, sounds like it's coming from the engine.
I have R&R everything even a bare naked GW noise is still there.
Went to Honda dealer who I respect the most service manager rode it and said it was ignition detonation mine was more quiet than most advise me to run hotter plugs and 87 octane only. Its a 09 Motor Trike has only 8500 miles on 08 GW.
I DON'T THINK I BUY IT...............
ANY IDEAS ????????? PLEASE HELP.
Thanks Bare

Welcome aboard bare. Listen to the service manager. You have a classic case of knocking. That is exactly what it sounds like.

 

[mingus41]

If it is engine knock, higher octane gas will fix it. Put some premium in the tank, its a simple test.

 

[Smoken'JOE]

Check heat shields too.

 

[trike lady]

What rpm's are you running at? My 1500 will clatter something terrible at low rpms in a higher gear.

The dealer told him to use 87 octane only ??

 

[Gorilla]

won't hurt to kick it up a bit on the octane. You will know right away if it works.

 

[skuuter]

Soundin' like "Octane Knock" as the others have stated. My Trike is geared higher than my stock Gold Wing was......I rarely use 5th gear now unless I'm well above 65 miles per hour because of the "Lugging" of the engine and the octane "clatter/knock"......definetly try the premium gas suggestion, although I lose about 1 mpg on premium. I run a tankful of premium through mine about every tenth tank or so just for the extra injector/carbon cleaners in it...."how I know" about the mileage.....

Re: 08 Gl1800 Engine rattle maybe UPDATE

It's been exactly a year dealing with this noise, as miles increased the noise got louder, all my trouble shooting always brought me back to the engine.
Today the clutch started slipping and the noise became louder---AW HA
More than likely the torque nut was never tighten to spec during factory engine assembly.
Thanks all for your help.

Ah.....guess it finally diagnosed itself.....

2008 GW1800 MotorTrike. Here in Colorado I always use 85. The last tank I got was from an off brand. It started to knock when I luggedat lower rpm. And it was more pronounced when going around a right hand curve. So I'm going to run some high test through it to see if that cures the problem of the knock. Wonder if the added weight of the trike kit dictates that I use a higher grade?
BARE, did you happen to notice that the noise was worse in the turns?

Maybe I just need to get those rpms up when I go through the turns.

 

[meredog]

Turn up the radio !!<br />
<br />
My vtx 1800 will "chatter" a bit if I let it lug down-----about 3400 rpm is it's sweet spot

UPDATE...........
Ok the steels and fibers have been replaced, there was always a thumping noise in the clutch basket at start-up when cold now its gone, however the knocking is still there I fill the tank with 93 octane NO DIFFERENCE DID NOT HELP.
No change in turns.
I am thinking that at 50mph in 5th gear is to low (That's when it knocks rattles)if I shift from 4th to 5th at 55 mph NO RATTLE.
Maybe you are right the trike Differential is higher than stock 1800 that and the weight difference is why more RPM shift points are necessary.
Does any one know the how much the gear ratio has changed??

[Smoken'JOE]

Mine will shake like the dickens if I shift to early. <font size="2"> (passenger seems to like it though)</font> <img src="images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" /><img src="images/smilies/grin.gif" border="0" alt="" title="big grin" class="inlineimg" />

 

[triwinggirl]

Have same rattle, had another winger listen to it he said it was normal. i listened to his new bike it had the same sound just not as loud.

Mine makes it usually when i'm decelerating, or in lower gears

 

[Papa Zook]

MotorTrike offers two different ratios. One close to stock and one taller. If yours has the higher ratio, you may well be lugging it at 50mph in 5th gear.

Do you know what the ratio's are please.

 

[Papa Zook]

Gold Wing 1800= 2.73 (3.08 was available but no longer offered)

Gold Wing 1500= 2.73 or 3.08

everything else 2.73

</div>Joe, is that why you put the grab bars on? <img src="images/smilies/smile.gif" border="0" alt="" title="Smile" class="inlineimg" />

 

[Smoken'JOE]

Joe, is that why you put the grab bars on?

:yes:...................My ratio is 3.55 (Jeep rear end)
Was wondering if a different ratio would increase gas mileage. With a little better shift.


1st to 2nd@20mph
3rd@35mph
4th@45mph
5th almost never before 60mph. Or is shudders. Ride mostly in 4th.

Folks at Roadsmith seem to think not.

Bear, if you haven't, I would check the timing on the engine. Not saying that is the problem That will cause the knock

Bare, If you haven't checked the timing on the engine, I would. Not saying that is the problem, but if it is out of time it could cause it to knock.

 

[EZglider]

Hey Bare,I had the same noise.The shop said it was the clutch and replaced it and basket.The noise was still there.It ended up being the alternator drive.It has a dampener and the clip that holds it together broke.Had to have engine removed to replace it.2200 dollars and it's fixed.Good luck.

 

[Dennis Elliott]

i wouldnt have believed it . my engine sounded like it was coming apart heaver rattle at about 3000 rpm slight knock at idle. turned out the cheap alternator i bougt on ebay the bearing was bad causing all of it i replced it and now just smooth as silk

 

[Solidbob]

You are aware this Thread is 4 years old....

Change your plugs...
Change your plugs...
Oh yes... i forgot to tell you

change your plugs....

I used to run 89 in my 05. I though well if 87 is good 89 should be great....
that is until I took a aturn on washington DC and my engine made noises like someone had dropped a box of flat washers in the engine...

I went to Wd in billings and it was very intermittent, that is untill I went up beartooth pass, and it was gone. I asked the Honda rep and he told me it could be one of 3 things.
Plugs, or baro, or vacum sensor.

Went back home changed the plugs....

KNOCK GONE. the plugs were covered with unburned fuel..
Went back to 87, and haven't heard detonation since.

I should have learned this from my mini vans. It calls for 87 and I once put 89 in the tank and it ran like CRAP.

But once the plugs are crapped out you must change them out, and after that go back to 87 gas.

 

[cavie]

VTX 1300 here. Can't use 5th till 60 mph.

 

[FRR]

I've read over and over that burning a higher octane in an engine that only requires 87 is a complete waste of money. Especially in this day and age when oil companies are widening the "spread" between 87 and 91 or 92. Used to be 20 cents, and now it is 40 or more in some places. Even the oil companies admit a higher octane is not necessary and they love to sell the stuff.

I've owned several Wings, from 1100 to 1800 and never had to run at lower gear at highway speeds and that means 5th gear at 40 MPH. Never seemed like I hurt any of the engines.

 

[Dennis Elliott]

I had the rattle . sounded like the engine was trashed. it was the rear bearing in the cheap altenator i bought on ebay. i would not believe that the sound would transfer like that. new bearings sounds like a sewing machine again

 

[Shimpy]

Skuuter, do a search, Google, on "top tier gas" , it is very interesting. Top tier gas is gas recommended by major auto manufactures, GM, BMW, Mercedes, Ford, etc, that contains cleaning additives to meet their specs. Only those gas companies that meet those min. requirements get listed. Most interesting is the requirement that those detergents that are used must be used in all grades of gas that they sell and at all their stations.
Sorry to get off the original topic.
