    I've used sea foam on my street bike to great effect. I've been thinking of running some through my XR650R that is fitted with a plastic, after market 4.5 gallon tank. Will the sea foam additive damage or stain the tank?

    I'm not saying it will or won't...But what do you need to accomplish? There isn't much in this bike to need "de-gunking" or cleaning out? Carb is simple and unless its had much sitting fuel can be cleaned with a spray can of carb cleaner and some time.

    Personally I wouldn't risk it...if you HAVE TO...use only enough you can run through within a ride or two.

    It should be safe on plastic...I used to run it in my KDX400 gas tank and never had any issues. I have never heard of it dissolving plastic floats either...I run it and MMO in all my motors, including car, truck, motrcycles, lawnmowers, etc...

    YMMV

    I work in the RV industry and use it in toyhaulers[some of which have plastic tanks] as a stabilizer . Almost all cars and trucks have plastic tanks now days and I have never heard of any problems.
