gas tank ideas
yeomans:
When I originally had the tank welded I was told the tank had to be new , the left over oil residue in a used tank from pre mix will mess up the plastic welding process.
I was worried about welding at first as well. The guy that did the work has owned his own plastics company for over 25 years.
He had done 2 other tanks for a guy in town before mine. Both of these tanks have ran the past two seasons with no issues, and both bikes are being raced. Both are two stroke CRs
The tank was also tested with pre-mix before it left his shop for leaks and held for two weeks, but still has not run next to my hot cylinder head yet.
I've also thought about running one of those pro circuit heat shields like the four strokes use, to help to cut down on additional heat and help to hide the welds.

I did find a company around here that fabricates polypro but of course, they won't touch a fuel tank. I think I read somewhere that kayak shops can do this stuff so maybe I can go that route. If nothing else, I'll just do it myself. Ya, that's it. Waste $300 and ruin a new tank.

What year chassis are you guys using?

I'm using the 99-02 kx 250 frame.
And yeah, the idea of ruining the tank scared me at first too.
I know the standard tanks for the 250's weren't an option for me, they don't hold enough fuel.
Even on my 250 in the woods with friends I'm always the first guy to turn around for fuel reasons, the four strokes they are all on sip gas compared to me

02 chassis her too. I have an 02 250 with an over sized tank on it. Need a new one though, right?
