Can you post a pic of the shorty ASV levers with your hand on the bar? Wanna see how many fingers stay on the bar and potential pinch points.

@Upgrayedd .....future hand model.....
Now we are going to class dubSolo’s thread up with some pics of my hands!

<Warning Hand Porn Below>

The F3 levers are forged I believe. The C5 levers are machined. I bet the C5s look a little sharper. It wasn’t worth it to me and I could care less about the 3 year vs 5 year warranty.

Let me know if you need pics from a different angle. My bike is in pieces right now. The front brake master cylinder is not even tightened in place at the moment.

I’m in the middle of about seven upgrades. Waiting on parts from all over the place. I may need to start my own build thread!

I ended up going with a custom set of Spiegler brake lines for my Brembos. Spiegler’s grommets fit perfectly in all of the stock brackets for the Grom. Better than Core Moto. I think I nailed the length and banjo bends. You guys will like some of these upgrades when they are finished.

Where did you feel like it signed off at?
You might consider the Yoshimura ST-2M cam too. Look at Yoshimura’s dyno charts. It loses almost nothing to the ST-1M cam down low. Someone else suggested that the ST-2M kind of makes the ST-1M obsolete. I don’t know, but it is a nice cam.

I wish my rev limiter was at about 11,000rpms. I’m currently at 10,000rpms, but would need stiffer valve springs to do 11,000rpms. It really starts to pull above 9,000. I would love to see what it would do above 10,000rpms though.

So, yea I've seen that mentioned before but I don't think I'll ever move my rev limiter above 10k.

I have a DHM head on the way and could do it, but I am building my motor to last and to be a daily driver 6-7 months of the year. I also don't care about top speed and will never take it on the freeway. My goal is to build it to be faster than stock and a lot more fun getting up to 60mph, but also to be able to ride it for 4-5 years before I go back into the motor hopefully, which is why I'm keeping the rev limiter down.

So for me the gains up high really aren't gains because I'll never rev it that high, so I'd rather have the minimal gains down low where I will actually use them.

It's a tough decision. I have a TB Parts and Koso cam that are brand new sitting on my shelf, so I could end up trying all three, but ultimately I want the one that is best for daily commuting on my way to work.

Well, that is what is fun about these bikes. We have so many parts to choose from, you can really build a bike for whatever your mission is.

Maybe the ST-1M cam would be better for what you describe. It certainly wouldn’t be worse. It would be fun to install both cams in two identical Groms, and drag race.

My bike sees pretty high rpms going 0-60. It doesn’t feel like it has lost anything in the low or mid range.

Reliability is a top priority for me too. My motor is overbuilt for the power it produces. If I go big bore, I will go with something that has a large enough bore to accommodate a forged crank and rod. I consider my crank to be the weakest link. I don’t worry about pushing it to 10,000rpms though.

I guess that is why I like the Kitaco Neo kit. I feel like it could be a very reliable setup, with descent power.

Koso over TB... Tb is just getting started at 9000rpm, Koso will be better for a daily city driver.
If you decide to pick up an ST-1M cam trial that one last, you will see what I mean by improvement everywhere with plenty of steam. Compared to koso it feels stronger esp at the rpms your wanting to hang around at least IMO...

That's exactly the kind of opinion from real world use I'm looking for... Gonna order a ST-1M today

Hey dubSolo. That spot between the ignition key and instrument cluster where you mounted your Trail Tech, does the Trail Tech rub up against the the cluster or anywhere else? Did you just stick it down or screw it in place?

Notice how no one posts in “Grom Talk” or “Grom Performance” anymore? We all just hang out in dubSolo’s thread...

It’s my new “safe space”.

I just watched the MotoAmerica Super Bike race from Road Atlanta on TV. Pretty awesome. I guess I could have gone to that, but I would rather go to Barber at Birmingham in September. Good grief those bikes scream. The Barber track is world class nice.

Round 2 will be on TV tomorrow.

Its wedged in there and stuck down with 3m tape, has a battery life of 5yrs. As far as I know no way to change, simply pull up and replace when time.

Barbers is 5 to 6hrs from me, will eventually make it to a Mnnthbx event.

Thanks for telling me about your experiences with cams....

It really lead me back to where I was to begin with, Yoshimura... Gonna get it installed next Tuesday.

David at DHM says the stock springs with his Titanium retainers are good to 11,000 rpm.

@dubSolo how many miles do you have on your DHM piston? Still no heat issues without an oil cooler?
