Anybody have a good fix for a pinhole leak in the bottom of a tank? Got the bike a few months back and started leaking around the petcock gasket. Ordered a rebuild kit with base gasket and still leaks. So I dumped the gas, filled with water and worked it around as pictured. Damn, got a leak in the dark area above the petcock mount. Looks like someone tried melting it to hold.

I had a small hole in the gas tank of my DRZ when I first bought it... Someone used a screw that was to long for one of the rad shrouds and it went straight through the tank. Anyway, I went to a auto parts store and got this sealant called "Seal All". It's specifically used to patch up gas tanks, radiators, ect. Worked like a charm and I haven't had any problems with it leaking since.

Here's a link to the exact product I used...http://www.google.com/products/catalog?q=seal+all&hl=en&prmd=ivns&resnum=2&bav=on.2,or.r_gc.r_pw.&biw=1024&bih=550&um=1&ie=UTF-8&tbm=shop&cid=6170833892599708899&sa=X&ei=NZ7eTaf6C4SXtwfZwtmMCg&ved=0CHUQ8gIwAA

Hope that helps!

Appreciate the help guys:thumbup: Seal All may be the easiest thing for me to get locally. Yamabond is surely good stuff too. I knew there was some stuff impervious to gas, I just didn't know about adhering well to plastic tanks.

I'm actually wondering if I'd be better off drilling a small hole to give the bonding agent a bite:headscrat

I don't know if I'd make a hole... Maybe just rough it up real well with some course sandpaper then clean the area really well with some alcohol or something.

Good luck!

I'll take your advice and try that first. After the repair and test I'll post the results (hopefully good):anim_peep:

Don't be stingy with it, I really globbed it on! Also, make sure you give it time to cure completely... Not sure what the directions say but I'd imagine at least 24hrs.

99% sure it is fixed! My buddy at work suggested melting directly at the pinhole with my soldering gun. Used my grandad's old gun (heats up in like 3 seconds) and formed a small roundish cavity. Tested with water and no leak. To be safe, I covered with Seal All and it's curing.

Thanks for the tips Junkies:thumbup:
