    I switched to a Jitsie aftermarket fuel tap, when my new '18 Scorpa 125 Factory leaked 2 years ago. That solved the problem for me.

    I would speak to the dealer you bought it from first. If they are no help, call Mike Komer at the Tryals Shop. He's sorted a few of these.

    Mine started leaking on my 2019. The fuel tank gets spongy where the petcock mounts. A thicker o-ring fixed it, no longer an issue. At least for now.

    Chill out.

    I was genuinely curious that this was still an issue. This was a known issue on the early ones.

    Good luck.

    Different O-ring seemed to patch the problem. Just my $.02 but seems those that run pump gas with ethanol seemed to have more issues (tank opening would warp) vs those that ran non ethanol based fuels.

    Might have missed it, but where is it leaking fuel from?

    I've run Avgas 100LL from new, so maybe that's why I have less of a problem?

    Where fuel tap attaches to the tank.

    The tanks warp and a fatter oring is required

    I spend a month or two in NM every year. Nothing seems to change with the tank. As @Boom Boom mentioned, ethanol might play a part.

    The leak started from new but only leaked when fuel was turned to on position as the hydro line was putting pressure on the fuel lever and making the undersized o-ring leak. I found some slack in the hydro line and pulled up out of the way of the fuel lever and installed a larger o-ring. IMHO the plastic thickness is just to thin at this location and the thicker o-rings just keep flexing it more require a thicker o-ring. Nephews 17 Sherco also leaked so moved the hydro line and stopped the leaking. Overall the Sherco / Scorpa is a fine product...just know you will have some fit and finish details to fiddle with.

    Like a moth to a flame I am. :rofl

    My POS Scorpa tank was leaking when we uncreated it and set it up, so yes, ethanol could make the problem worse but is not the root cause.

    The fuel tank is obviously made in some kids backyard plastic injection mold kit. The quality control or the mold is crap.

    The problem is right where the petcock mates to the tank, the plastic is super thin and WILL warp when the two bolts that hold it in press it tight against the gasket or o-ring. The surface is thin, wavy, flat, etc. Not at all what anyone in their right mind would create to form a gasket seal surface. Some guys have apparently had luck with using a larger o-ring but on some, the gap is just ridiculous and a new tank (which could be the same) is required.
    It’s a known defect that the team riders all suffered through at a NM national and that the importer doesn’t want to deal with. They actually tried to SELL me a thicker gasket when approached about it by my dealer!!!! WTF?

    If you compare with the Sherco tank, there is a nice thick boss area where the petcock mounts and the threaded nuts are embedded. Obviously, Scorpa is sourcing tanks from a different manufacturer.

    I personally am not going to support or recommend a $9K bike that entire management chain knows has this defect but will not back-up or even acknowledge the problem.

    Is the bike really that superior (in what ways?) to purposely buy knowing that it has a good chance of having a leaky tank and/or fixing it for them after the sale? That, IMO is just :loco
    There are several options out there that don’t come with this gremlin. If the bike “fits” why not just go blue and give Sherco your money? You can still drain the tranny oil out of a case bolt. :imaposer

    There. Now can we talk about Beta clutches?
