Disturbing Find Inside New Carbs - RS34

I did empty the tank a few weeks ago and never noticed anthing out of the ordinary. I run dual inlets and each has a filter with a cleanable brass element. I'll pull the filters and take a look.

As soft as this stuff is, I don't think it would even clog a filter. It seems to disolve almost immediately when handled and might disolve in gasoline too, not sure. It seems to have formed in the bowls rather than traveling from the tank, but I can't know for sure. The screens on the petcocks were clear, by the way. I pulled those out and would have noticed if they were clogged up. I run dual pingels, one on each side.

I'll take a better look at the tank and see if the liner looks OK. I can only hope it was the stabil and not the liner. The stabil I used is definitely pretty old, I wonder if that has anything to do with it?

I have have had little luck with lined tanks...with both normally aspirated bikes and FI bikes...I usually end up getting a new tank...the lining does dissolve and you should see what it does to fuel injectors and the head and valve stems of a FI bike:laugh:

I coated the tank with kreem liner and it held up really well for 15 years, no problems. When I decided to rebuild this bike again, I wanted to have the tank redone since the kreem was so old. I went to a professional "gas tank renu" franchise and had it done, hoping it would be as advertised. It might be the liner, but I sure hope not.

Here's some info on what was done (only inside coated on motorcycle applications) -

I actually contacted the franchise dealer here in Texas about the 'gastankrenu' and he quoted me US$250 and he'd have to cut 8 to 10 holes in the bottom of the tank (which he promised to weld up) to get even coverage. I declined (and not because of the price either:) )

I would take a sample of that stuff to a college chemistry lab and have them put it under a microscope to see if it's alive. It could be some sort of microbe that's thriving on the fuel/liner mix. You may have stumbled on a new life form. Ed

They only charged me $100 here in my area and had to cut a hole about 2" in diameter on each side of the tank bottom. They were soldered / welded back up and can't be seen. The coating looks really good - I just hope it's not falling apart and filling my float bowls...

Good point, with all the home foreclosures these days you find things living in the strangest places.

I had some stuff like that end up in my bowls(not as bad though) on the ZRX after using Stabile. I don't use it anymore. Next time turn the petcock off & drain the bowls.

Just close them up quick and the problem will go away. Then send me that bad tank.:laugh:

I wish you guys would have looked into POR-15 before spending that kind of money. I've done several tanks now and all with excellent results. I can understand "once bitten twice shy", but this stuff works. And if you buy any of their products I don't even get a red cent from them.

ouch... I've never seen such mess in carbs, do you have such bad gas up there??
I never use additives to my gas. My bikes just fire up without toubles on 6 months old gas...(for 20 years that is). But I do drain all float bowls prior to storage by just closing the tap and waiting.

I advise not to use the stabilizers etc... there only good for the manufacters

A while back I stopped and got gas, the station was out of reg, so I put the high dollar stuff in and never gave it a second thought, well, it had some kind of crap in it, plugged up the fuel filters and the screen in the tank.
the filters did thier job and nothing got to the carbs.
I would not rule that out
