    Just wondering if anyone knows how and what can be used to seal secondary holes in carb pistons? The image shows the normal carb piston for a ZXR250. The standard hole has a secondary hole next to it. I want to seal the secondary hole, but am not sure what's the best way to do it and/or what material to use.

    Any suggestions would be greatly appreciated.

    You could try vulcanizing rubber. Same stuff they use when plugging a tyre.

    I have some of that material, but is it fuel resistant? I'm worried that fuel might erode it and then something gets sucked in to the engine.

    Sikaflex. Fuel resistant and is the stuff that sticks sh*t to blankets.

    Thank you Gentlemen. Bunnings only have Grey colour SIKAFLEX. Risky, are you saying Black is stronger than White tongue-in-cheek or for real?

    black is more resistent to water and fluids. can be submerged for long periods of time where white cannot be.black is definitely available at marine suppliers but is also what holds car windscreens in and crummydoor firewalls in place.

    Too much PC BS. Meet & Greet should be a hoot.

    Risky, are you drag racing this weekend?

    Off to the F1 GP tomorrow. Those stadium trucks look like fun!

    Enjoy & take a few pics if you can.

    I'll mark the 2017 Nationals in my Calendar. I haven't been to Tamworth for ages.

    @risky & @Murdo

    Risky, with regards to the Silkaflex....

    Did you mean the one on the right (in the colour Black) or the one on the left? There's a few of these, so I want to make sure I get the right one first time and I don't botch the repair.

    The one on the right. You should be able to buy it in smaller tubes too.

    Yes, that's right; Bunnings have it in the smaller tube. The one on the left only comes in "big job" size.
