Head pipe rattling loud
« on: March 28, 2011, 06:46:53 PM »
Today I went to ride the G5 and noticed a loud vibrating rattle when the engine was revved. It is coming from the right side. I first thought it was something in the right side cover. Then I traced it to the exhaust, thought maybe the muffler. I took off the muffler and it didn't rattle. I then hit the head pipe and it rattled a lot. It sounded like there was something metal in the pipe bouncing around. It seems like it is coming from the bottom horizontal part of the pipe or at the bend. I looked inside the head pipe and there is an inner pipe on the horizontal section near the bend. I think the weld is broken loose and the two pipes are rattling against each other. Its really load and annoying! This seems like it would be a warranty issue? My warranty is up in May. Anybody else experienced this rattling head pipe?

Sounds like a warranty issue to me, I hope it's easy to take care of.

Check the heat shield.  It should be attached to the head pipe with a little clip where it comes close to the foot peg.  If you can lift it away from the pipe with moderate pressure either the clip on the pipe, the shield, or both may have broken.

This happened to me and it was amazingly loud and annoying.  And yes, it's a warranty issue.  My dealer got me a new shield lickety split.

I don't have the stock muffler and heat shield. I have one similar to the EFI silencer. I removed the heat shield, still had rattle. I removed the silencer, still had rattle. With only head pipe left I can hit head pipe with hand and can hear rattle from bottom of head pipe. Here is a video of it by a bad cameraman :D

Hold on here, my Bullet developed an intense BUZZZZZZZOOOOOOMMMMM  :o when I was shifting up at high revs. I have looked eveywhere seriously and can't figure it out. I'll have to try this out and see!

Did you check by simply tapping your header pipe?

Would this require a whole new header to be installed in order to fix?

like r80rt tried to tell you, call the dealer for them to
check it out.
it's fun to work on things and do maintenance,
but you have a warranty for problems like this.

I have contacted the dealer and he is going to check with CMW on the warranty. The dealer is a couple hours away, so it's not the easiest to just take it to them. I have to take it to them on another minor issue, so i am trying to coordinate it so both issues can be addressed at once.

While revving the engine you can use a piece of tubing to listen for the rattle. Place the tube on the head pipe just after the lower bend. Or as I did in the end to confirm it, I took off heat shield and muffler just leaving the head pipe. You can then just bang on the head pipe while the engine is off to hear the rattle. I believe jjoe256 meant they replaced the head pipe all together.

P.S.
By the way the engine sounds pretty good with just the head pipe, not as loud as I thought it would be. I actually took it for a ride to town and back and rode past a cop taking radar. Just went easy on the throttle as I went past him.

Found out today the head pipe will be covered under warranty. Unfortunately CMW doesn't have any and has to get them shipped in from RE India.

Is it hitting the brake lever? Mine did. There is  a set screw for the brake lever. Guess not..

On a side note, I also I had a nasty rattle coming from the front and it turned out to be the forward bolt that holds on the tank. It was loose!! I used some rubber up under the tank while I was at it and its been silent.

If it's like mine, its the headpipe in the vertical section.

Yeah, I'm still waiting. I hope I don't have to wait 5 months like you did for your replacement head pipe!!!

Got my replacement head pipe today. The new pipe has a heat sink at the head which the original did not have. The chrome is not quite as good as the original. It's more like the wheels but a little shinier. At least I don't have that annoying loud rattle anymore.

It looks quite good and so does your bike ! 

Your front tyre looks different from what I have on my G5.  What is the front tyre ?  Any special reason for changing ?

Thanks

I just recently replaced my original tires with a set of 3.50 x 19 Dunlop K70s. I wanted to try a tire that has better grip on loose surfaces (gravel roads) and had a more round profile on the rear. These K70s definitely make the bike handle better, more nimble. Unfortunately I hear they don't last that long, wear fast, as they are made of a softer rubber for better grip. I'll see how many miles I get out of them.

Damn, my boat must have come in! You got that quick! What's your mpg with that exhaust? Looks good. I have a similar one but not as long.

I haven't checked my MPG lately. Last time I checked, I had this silencer on, it was around 75 MPG. I'll have to check now that I have the 18 tooth.

It's this inexpensive silencer from Bulletwala (India)
