Grom

Finally got my Grom out on the kart track for the first time yesterday for a track day. It was fun, and I felt like I was moving pretty well. Until the NSF100s and CRF150s blew by me. The kart track race scene is pretty serious here given there are no full-size race tracks in Okinawa. But it was a good time anyway. No complaints about the suspension (YSS shock, Ohlins cartridges) or the Kenda tires, but it was my first time ever on the kart track so I’m sure I wasn’t at the limit anyway. -1/+1 gearing was still way too tall, I didn’t get out of 2nd gear, but short tight little track (the lap record is 23.5 sec) so less manic shifting might have a silver lining. Despite the purpose-built kart track bikes being heaps faster, I could see it could definitely be an effective training tool for big bike racing anyway.

 

time to keep this thread active.

Hard Racing has a nice Black Friday special going. Just ordered some clutch stuff. Going to be ditching that heavy oil spinner and using an actual oil filter.

• Kitaco Clutch Cover '13-'20 Honda GROM / GROM SF
• Kitaco 60% Stiffer Clutch Springs
• Kitaco Billet Spring Plate
• Takegawa Super Oil Pump
• Optional TOOLS

 

Thought about posting about that but didn't know if anyone cared about Groms anymore.

If only there was a HardRacing site for dirtbikes...

 

Smart choice buying the tools. Idk what kind of pain in the ass it would have been to try to do the job without them, but it was a breeze with them.

 

learned my lesson doing the forks. thought i'd save a few bucks by borrowing a friend's Z125 fork tools to find out they're totally different. waited a month to get them, and still had to buy the Grom fork tools in the end.

 

You know an upper cut just got packaged at a UPS store and will be at your front step tomorrow requiring a signature, right?

 

The surest way to guarantee a higher expense and a longer time frame is to try and go the "save a few bucks" route.

 

You need to get an Ohvale on a Kart track Bud.....The Grom is a great little commuter, no doubt. Won't debate that.

But for stupid mini cheap track practice fun....Ohvale.

(Meaning the track time on a kart track is cheap...not saying Ohvale's are cheap.....just to be clear).

 

I ain't signin' shit.
Return to sender.

 

ok so after installing all my parts, my Grom is now maxing out at 67 MPH down hill (speedo corrected).
i have -1/+3 gearing and noticed after 60 MPH, the front starts to wobble.

not sure if i should drop a tooth in the back or not, but then need a steering damper.
plan is to be able to cruise 50-60 without the motor screaming.

 

At first I read this as 67HP and thought what in the hell did he do to that thing? Then it occurred to me it had to be a motor swap before I realized it said MPH.

 

Groms are super fun, but outside of a spec grom class, they are expansive to make competitive.

 

How much do you weigh?

 

225 lbs

 

exactly! 6 feet tall, 225 lbs on a Grom.

 

I’m 6’3 and “down” to 230 these days - it can be done. But I fear for what you’re looking for in a Grom you need either the full big bore treatment or an engine swap. Between those two, I think a swap is probably cheaper and more reliable (but that’s supposition on my part).
