    My 2018 ABS build

    Hello,

    First off, thank you to everyone on this forum, as I've learned so much on here already. This is my first bike. Thanks to HardRacing for selling me so much stuff.

    So I did a bunch of mods in the last couple of days, so figured I'd post about it here. I bought a used 2018 ABS Grom about a month ago. As far as I can tell, the previous owner didn't modify anything other than an AR exhaust and the Yoshimura fender eliminator kit. It looked like this.

    Today I installed kitaco springs, chimera intake, Takegawa S type cam, dynoject PCV, kitaco clutch cover, and takegawa oil pump. Tomorrow I'll put on the 14T front sprocket and the Koso DB-03R dash so I can fix the speedo after the sprocket change.

    I also put on TST flush front blinkers and the CustomLED integrated taillight. And lastly, (but most importantly to me because I can't stand the gold forks), wrapped the forks with matte black (actually my daughter did ).

    In terms of installation.... I don't know the first thing about bikes or working on them. But I did everything myself. YouTube was my friend. I didn't have any issues really. However I'm not sure about valve lash. I have no idea if I did it right. I'd love for someone who knows what they're doing to double check it for me. Anyone in the Phoenix area? HardRacing recommended I go with 005 for both valves, and I tried my best to do that. I also flashed the ECU with the map HardRacing gave me.

    Some observations after just firing up the bike and going for a ride...


    • The bike is MUCH louder now. It's actually kind of disturbing as I was not expecting that. Makes me wonder if I put everything together right. Any ideas why the bike would be so much louder now? I mean it is MUCH louder now... geez. It's got to be too large of a valve lash gap or something....
    • The clutch springs are awesome. I wasn't sure whether to go with 30% or 60%, but decided on 60%. That was a great decision, because the shifts are so quick and smooth now. However there is a lot of "chatter" in the clutch when I slowly let it out. Is this normal?
    • In a quick top speed test, I gained 1-2 mph. Stock I was only ever to go 54. I hit 56 on the way home just now. Honestly, I'll give those gains back after I install the 14T sprocket, but that's ok I guess. The BBK will fix that.


    Lastly, I have a set of TST flush mount blinkers if someone is interested in buying them. They are essentially new. I installed them on the rear and did not like that look, so I took them off and went with an integrated light.

    Thanks for listening, ride safe.

    Ok. I used a tappet tool and tried to reset the valve gaps. I ended up widening both of them a bit. Still not sure if they're set correctly as I'm not sure what the feeler gauge should "feel" like when it's in the gap. It lightly scraps as I test the gap, so I'm assuming that's the "feeling" I'm looking for.

    Took it for another ride and hit 58 mph. Stock, my top speed was 54. The engine really screams above 6k RPM--and I mean that in a loud sense. It's so loud once it gets to 6k. I am thinking now all the noise is just the cam. Sounds cool while idling too.

    Can hardly wait to install the front sprocket and Koso dash tomorrow!

    The way it was explained to me was the feel you want when using the feelers is as if you're sliding metal over a magnet. Slight resistance.

    I've attached a recording. Sorry if I'm worried about nothing, I just want to check with people who know more than I do (which is essentially everyone )

    Hear anything in this audio that sounds like trouble?

    Swapped the exhaust for a dual high mount. Love it.

    Sounds normal to me Farmboy. Although I can only hear the exhaust note.

    The reason I did not go with the Koso dash is because the common consensus is (was) that dash will not correct for a sprocket change. Did you get it to correct?

    Yup, it's correct and awesome actually. I've run my speedo GPS app on my phone alongside to verify. Got in all dialed in. The dash is cool actually. Love how it integrates so much into one gauge.
