Re Roger:

Is gas tank leak unpatchable?

Is it costly to swap / retrofit gas tanks?



To all : Bike now sits at garage at parents'. Needed a can of seafoam to get the engine going.

The tank looks rusted but how in hell did it rust at that point.
Does the tank leak?

Get to a safe work area and drain the fuel and inspect it.

DO not drive the bike like this.

I have spare shoddy tank that is prisitine but it would cost a million bucks to ship it to you.

I patched a leaky Seca 900 tank with Permatex Gas Tank Sealer epoxy and it worked, but they wouldn't pass it on inspection, so I threw $800 Yamaha's way for a brand new one. If you don't need to have it inspected, the sealer works as advertised, but you might find you need to bring a chunk of it with you when you ride. My GS1100 was like that, so I sprung for a NOS tank from JT Cycles in Battle Creek Michigan off of Ebay for $300.

Thank you all for the advice and information. After the oil change and a fresh tank of gas and sea foam, the bike is running fine now. There is still a little bit of oil leak where the engine will be wet , but not so much that there is any drip on the ground. I have decided not to touch the engine for the time being.

Gas tank seems to be holding up fine. Bike goes up to 120km/hr no problem. Yes the power really does come after 6k rpm.
Will continue to monitor for gas leak.

Took off the old broken fairings and did a round headlamp swap. How do I post pictures?


Found out the lights on the gauges are dead and I can't read the speedo / tech at night, anything I should be aware of before I take the guages apart?
