Hello all,

It seems my tank on my 2000 M2 Cyclone is making bit of noise. It feels loose up front. I tightened the bolt under the seat and that did not do anything to solve the problem. Anybody have a way to tighten up the front of the tank?

Thanks
Mike

Unfortunately, no. The front of your tank has a "tongue" sticking out that engages a little bar attached to the frame. No fasteners involved. If the tongue is tweaked, cracked or missing altogether it will be loose in front.
Has the tank been off your bike recently? Maybe the tongue is sitting on top of the bar instead of underneath it. It is visible looking down right behind the steering stem.

MFell,

Take the tank off (or raise it up) and rotate the two rubber bumpers back facing up on the frame rails. reinstall tank.

Mike,
Get a one inch long piece of 3/16" inside diameter rubber tubing. Slice it lengthwise along one side. Remove your tank (pull fuel line first) and install the piece of tubing over the metal bar that the tank's tongue engages. Reinstall tank. :)

Also, when you have the tank removed look for rub spots on the underside and in the relief channels.

Ah yes, the fuel tank noise.

On my 00 M2, the burbling noise the tank made when it contacted the frame rails was one of the constituents of the "chitty chitty, bang bang" cacophony that eminated everywhere from my bike.

Especially annoying when trying to look biker bad entering or exiting parking lots.

I did like Mikej and identified the offending areas by the telltale rub spots. I had some 3/16" thick rubber that I cut into strips and glued to the inside of the tank. I'm surprise the strips are still holding fast; thought for sure the bike would spit them out on the first ride. If it ever does, I'll do what Blake recommends.

Odd thing about the rubber I had. It was the left over insulating material I got in a Herb Adams subframe lowering kit for my Camaro over 20 years ago. The original use was for keeping the floorpan of the car from vibrating against the raised subframe rail. I also used it to noise proof the flyscreen against the speedo. It's working surprisingly well.

I knew that stuff would come in handy one day.

Thanks for all the great ideas guys. It took a long time for me to figure out it was the tank making the noise. It was hard to hear since my exaust hanger was making a sqeaking noise. I just updated it to the newer hanger so say goodbye to the sqeak. So I have one more noise to get rid of and that should do it. I still love this bike. I can deal with tightening a few nuts and bolts once in a while.:-)I have one more question for which I will create another thread.

Thanks again guys
Mike

Sorry for what was apparently bad advice. The tongue on my '00 M2's tank cracked off at about the same mileage your bike has. When I asked the dealer why it would take 3 months to get a replacement tank, he indicated that the problem was widespread, and tanks were in short supply. Obviously, not true. My apologies.
