My M2 sat for many years new without use. I bought it 6 months ago and it just started weeping fuel about a month ago from the top of the tank at the base of the chrome filler and the tank. I figured it was a dry rotten seal so I bought a seal from the dealer. FSM doesn't provide any info on replacement and I couldn't find anything in badweb search. Pulled off the filler from the top of the tank today and found some white residue under the old seal and found it to be a little distorted. Installed the new gasket without any sealant and the thing is weeping like crazy so obviously something is wrong. This might be the most basic thing but I don't know what to do. The gas on the tank has also destroyed my tank decals and they are bubbling. The dealer says they can't get the decals anymore (PN 14602-95Y) but can get newer decals but we can't determine the size. There are many threads on this but I haven't read anywhere on badweb what can be done now after dealer decals are gone. I have seen the $65 eBay decals but that is a last resort. First step is probably to gently take a heat gun to them because they are starting to drive me crazy. | ||

Use hylomar as a sealant on the gas tank ring and seal. Follow the directions on the hylomar tube and you will not get any leakage (most auto part stores or marine supply stores carry it - it will be with the other Permatex products). As far as the decals, the newer style are the thicker (about 1/16") stick-on decals. I believe they are slightly larger than the older decals that tend to bubble off. You may indeed have to remove the old ones first or you will be able to see them below the newer ones, plus you would be sticking the new ones onto a surface that is coming off, which wouldn't be good. | ||

What year M2? Early models had issues with the filler ring seal and had to be resealed, they also had a free replacement on tanks that bubbled. I never replaced my tanks because neither bubbled until just about a year ago. | ||

I believe some of the recalls on the tanks included a so called upgrade to the 3d graphics. Your best bet is to find a good painter and have the graphics painted in at the same time you repaint the tank. Good luck! | ||

Thanks guys. It's a '97. It's has no recalls done but hopefully getting all completed next month but I don't remember anything related to the tank on the list. I'll hit the auto parts after work and ask for a polyurethane sealant maybe they'll have Hylomar. I'll try to clean up the edge w/o loosing too much into the tank then follow the directions on the tube and cross my fingers. Should I apply sparingly or generously? Around the edge only or down the middle? How bad would it be to loose some sealant into the tank? I also noticed that the tank is plastic and it looks like the cap screws are going to pull out if over tightened. Any guidance is helpful I have some auto experience but I'm very new to working on bikes. I'm trying to avoid making uneducated guesses and botch my 'new' bike. I appreciate everyone helping me this forum is great. | ||

A little Hylomar goes a long way. Too much and it will keep on oozing out around the ring and onto the tank. | ||

Hylomar is not in stock anywhere around me- marine shops, auto repair or motorcycle shops. I could order some online but its at least $25 and also, I want to ride now! Does anyone know a common alternative? | ||

got any truck stops around you? They will have it. I personally wouldn't use anything else on an application exposed to gasoline. Or you might be able to get it from Pingel website. | ||

Definitely use Hylomar and do not substitute anything else! I've done this a few times, and I recommend generously applying it. Yes, it will ooze out and you will have to wipe it off, but this is the only way to get a good seal. I have had to reapply the Hylomar once on my '96 S1 since the repaint after I noticed some fuel weeping out. After reapplying, no issues. This paint job is 6 years old now and no bubbling (knock on wood). I thoroughly believe this is due to a good Hylomar seal...apply generously! | ||

Found Hylomar on ebay for 10 bucks. Seller was great even shipped it out in time to get it repaired for a weekend ride: http://www.ebay.com/itm/190729202346 (Sold by jarrot) Anyway I thought I had spread enough around to seal it but after a few hours I swooshed the tank back and forth and it was still leaking. So I cracked it open again and really went crazy around the edge. I put down blue tape to keep it off the paint because when I screwed it back on it did ooze out but some alcohol on a clothe took it off. It's not a super clean job and the blue sealant can be seen inside the seam. I swooshed it around and there was a little weeping in one spot. But after a ride it was dry so I don't know if it cured or if I'll have to pull it again. Either way thank you all for help I appreciate it very much. | ||

Did you let it cure for 10 minutes (or whatever the correct time was) before sticking the parts together? you should not have had any weeping | ||
| Wesleyb82 |
It didn't specify a time frame on the tube just "allow evaporation after application before reassembly" or something to that effect so I think I let it air out for 3 or 4 minutes before sticking it together. |
