Well, I got my reflashed ECU back from Cameron Jones on Wednesday. Installed it and finished putting the bike back together. Rolled the bike out on the driveway, hit the starter button.....it fired up and ran fantastic!
Idles perfectly, but definitely sounds like it has a more aggressive cam now. Sounds meaner.
I’m not talking about a bunch of clicking, clanky valve noise. There is none of that. That aspect sounds stock. I mean the Grom kind of has a noisy motor, but this is nothing like what some people describe with the TB cams. I’m guessing the Yoshimura cam having a larger base circle diameter contributes to this. I will check the valves again before too long.
So far, it runs great, but unfortunately the weather has been total crap. I’ve been unable to go out and really give it a proper test ride.
Riding it around the neighborhood, it feels like it lost nothing on the low and mid range, no joke, but at about 6000 to 7000 rpm, I can feel it wanting to really start pulling. Sadly, that is about as far as I got with it. My neighbors were already looking at me like I am some sort of punk. Hopefully this weekend I can go on a longer ride between storm systems.
The intake doesn’t sound any louder so far. We will see at high speed, if that holds true. The Koso intake snorkel and Koso connecting tube really open things up, but seem pretty quiet. Just what I wanted. The DHM adapter seems solid too.
I have changed so many variables on this round of upgrades, spanning a couple of months. The ASV shorty levers are a dream. Kitaco 60% stiffer clutch springs, feel like what should have come on the bike to begin with. Kitaco billet clutch lifter plate, Kitaco titanium tappet nuts, Kitaco adjustable shift link, Kitaco 1/2 pound lighter rear sprocket, Kitaco aluminum axle spacers, Kitaco cam chain tensioner button, Kitaco 3-row super oil cooler, Kitaco hose separators, Takegawa cam chain tensioner, Takegawa 4th crank support bearing, etc.
The Ohlins shock feels way more plush and properly sprung for my body weight. I am holding off on installing the Kepspeed swingarm until I can figure out a better chain slider for it.
I’ll report back on the Yoshimura cam, once I can take it out on a serious rip session.
