Yes. The holes are at the bottom and a little way up the sides. The holes are small and are surrounded by enough good metal so that I can have them brazed. Before that, I need to get the KBS coating out. They claim a paint stripper with a high % of methylene chloride will work, but that's pretty nasty stuff. I guess I have no choice if I want to use the tank. Assuming I get all of the KBS out and braze all the holes, how is the PR1005L applied? One of the problems with this tank is that the baffle at the top makes it impossible to see any of the inside surface of the tank. How will I know when the entire surface is covered? I have the same problem with the stripper - how will I know when all of the KBS is gone? P.S. I'm checking daily on Ebay for a tank in better shape. Thanks.

Thanks, Tony. I may try that. Their Web site indicates they deal with very large tanks. Do they offer a product small enough for an RZ tank? If so, is it available in the US? I had the same problem on my 1983 powervalve and found a product in the UK available from Tankcare products known as PR1005L which you slosh inside the tank after it has been fully degreased and then let the excess run out.It leaves a flexible coating on the inside of the tank which is fuel resistant and is what they use to line aircraft fuel tanks.Don't use the epoxy type coatings i.e petseal as these will eventually start to break up.Tony.

Thanks bowser. The KBS kit contains a solution which seems to have eliminated the original rust, but it also opened up new pinholes which did not immediately appear. I'm looking for a sealer to use to seal the holes after the rust is neutralized. It's possible that my tank is beyond repair.

The tank on my '84 RZ350 developed pinholes from rust in the lowest part of the tank. (It's a common problem.) I tried a sealer kit from KBS Coatings. It sealed the tank initially, but three days later sprang several leaks. I bought a used tank from an '85 RZ which is much more solid than mine was. I want to seal it to prevent rust, but I want a sealer that works. (I'm leaning toward POR-15) I'd like to hear from anyone who has had experience - good or bad - with any brand of tank sealer.

Check with your state's DMV or inspection agency (if your state inspects motorcycles). Fiberglass fuel tanks are prohibited for street use in most states for the reason given in a previous reply: in a crash, they can shatter and leak. That not only endangers your life, but also anyone in the area. I suggest that you follow the advice of this manufacturer of fiberglass tanks. http://www.airtech-streamlining.com/yamaz/RZ3501984-86.htm
