    Repeated high rpm riding

    How is the grom handling being topped out for miles on end? I’ve been riding 30 miles, mostly topped out on an every other day basis. Not what I intended to use the bike for lol

    I race mine only and am at redline a lot. Oil is now leaking into the cylinder and causing me to lose power and burn oil. I have no idea if this is related to high rpm or what but I thought I'd share my experience. 1800 miles on the bike and it could just be I got a lemon who knows.

    If you're still running the stock spark plug, I would recommend going down a step or two colder. I'm running an NGK CPR7EA-9 spark plug, which is a step colder and it dropped my temps from always being borderline catastrophic to 20 degrees or so lower.

    I think you've fallen prey to the dreaded 'confirmation bias', happens to the best of us. A 'hotter' or 'colder' spark plug doesn't affect the engine temp, the following description could be helpful here, from the NGK site:

    *When a spark plug is referred to as a “cold plug”, it is one that transfers heat rapidly from the firing tip into the engine head, keeping the firing tip cooler. *A “hot plug” has a much slower rate of heat transfer, which keeps the firing tip hotter.

    If stock or lightly modded and well maintained it will take the abuse no problem.

    I have a 2014 grom that has over 15000 miles, i ride it almost daily and usually run about 55 to 60 most of the time. I do all the regular fluid changes and chain checks and air pressure and its been all good. I wont bounce it off the rev limiter or go above stock red line. it is a honda and they can take a beating but why beat it?

    I'm also in the "why beat it up club".
    I ride every day for business and personal use... most of the time in the 4K to 6K range... and never over 8 because there is simply no need for it.

    2017 here......about 5000 miles or so on a mostly-stock engine. My bike is ridden pretty hard, and the engine spends most of the time at 6500-9000 RPM. I am careful about the oil, and have changed the oil frequently in the past (full synthetic). No issues thus far.

    5,500 to 8,000, anything less is just an idle.

    Sometimes I forget it's a 4speed and try for one more ;-)

    What RPM is the stock rev limiter? My bike has always seemed to rev into the red on my gauge.

    Hitting the rev limiter one in a while won't hurt anything though. Living there is a different story. High revs wear engines quickly. You can't beat physics.
