    Valve part number is changed for 2019. Cam part number changed for 2018, but 2018's don't have the valve issues.

    I wouldn't push the stock retainers past 8300rpm. Wave jumping a modified ski that has the rev limiter removed with a factory valvetrain is asking to chew up a valve and piston and potentially lock...

    Sure would be cool if we could get some prop measurements from that stock 79mph prop!

    It has been super hot here. I haven't seen under 85 degrees yet. It runs about 76 dash in that weather with intake/exhaust/catch can/scom.

    If you are seeing 79 Dash with just a SCOM, id keep your stock prop. I couldn't ever get the dash past 73 with SCOM only. Sounds like a factory freak.

    This is exactly what I was looking for. I didnt see the point at 11 hours having guides and seats redone. I can swap the valves, springs, retainers, and maybe stem seals and call it a day. Probably...

    I'm mainly doing mine because I only have a 1 year warranty and I bought the ski with the intent to modify it. I can't rely on the warranty or the factory valves at this point with so many confirmed...

    Ill look into it. I wasn't really looking to do any porting, just upgrading parts, so I may do it by myself.

    2019 300 valves

    After all of the talk of 2019 RXT X's dropping valves, I have finally decided to be proactive and pull the head in the off season. Supertech springs and retainers are a given, but which valves do you...

    If I ride in sport mode, I get the 2 bar gas warning after about an hour tops. I figure that it's just normal. The tank is small and the motor is huge.

    The TX received a new valve part number for 2019 and a few ski's have dropped valves on #1 piston. Hard to say if it's a limited issue or the entire model year. Springs and retainers have not fixed...

    I have a 2019 RXT X 300. No issues with the ski itself so far. Had some SCOM troubles, but those seem to be Riva issues with the SCOM not working properly. I would recommend buying the 2020 model...

    Im out of reasonably simple fixes then. Sounds like a new cam profile must be the issue if springs and retainers aren't helping it. Hard to imagine that a simple valve alone could do that. This is...

    My power seems to vary a lot as well depending on the day. I think an intercooler might make things more reliable on any given day.

    Has anyone with a 2019 with upgraded springs and retainers dropped a valve yet? Or just stock skis?

    Seems like an even better reason to do springs and retainers now to help prevent chewing up a valve.

    I agree completely to buy the bigger charger. OP stated he has zero intention of running above 8500rpm. Whats the point of a XXX or 142ET at that range? Pretty much nothing.

    In my opinion the bigger chargers shine in the upper RPMs. Your best bang for buck is just replacing your factory compressor wheel with a XX wheel which will give more boost for 1/3rd the price....
