A friend of mine does account work for Dyno Tech in Las Vegas, at the Speedway. She invited me to bring they Grom in. One of the guys likes small bikes and wanted to check it out. They threw it up on the Dyno and this is what happened. He asked me to bring it back with the stock exhaust, so he could get a baseline. The Tyga didn't do anything. It's still 9hp. I haven't done anything to the airbox yet. I doubt it would change much. Everybody liked the bike. Here are some pictures. I did get it to 61 on the way home, in a tuck. :D





He could have used some lube. :eek:

So, the Tyga Carbon Oval slip-on did not increase power at all? Hmmm. But at least it does sound really good, right? I mean does it sound really good? And does it get hot?

I think it sounds good. It's not obnoxiously loud. I haven't put my hand on it to check. I'll get my infrared thermometer out next time I ride.

so this confirms the idea that slip-ons are jsut for sound and looks.

now we need some with a full system to get their grom dyno'ed.

i will have my yoshi full hopefully on friday, but how juch does it cost for a dyno?

When they sort the big bore kits out, I'm going to get a 150. I think that is the perfect balance between getting a little more go, and rebuilding the whole thing with cams, oil cooler and whatever else you need to really go big. I think if I can get to 60, with a little left over, that would be pretty safe on the road. I could get away from most anything.

I know I need to re-gear it, but that stuff just give me a headache. I want to get off the line faster and generally get more speed. What sprockets do I need for that?

looks like it helped to me, not peak power, but looks like a little more mid range, graph is smoother and looks like it hold power slightly better up top, but two different bikes on two different dynos, hard to compare, wish you would have got a stock baseline

Love the white wish that was an option. I dropped two teeth in the front and I can hit 65 easy now and I'm no little guy. We should do a ride when I get mine back from Dyno Jet.

Well yes, of course sound and looks. And keep your cat. Some dude on here did over 70 stock. Until I get mine, I will go by that.

A good gearing setup for the stock grom is -1 counter shaft and +2 rear sprocket. The dyno looks good except the AFR, looks pretty lean throughout. A steady 13:1 across the board could def. improve your RWHP. Does anyone know if the Grom has a rev. box separate from the ecm? The next step for you would be a fuel controller and dial in your AFR.

So you're the one keeping me from a free PC. :wink:

They called Dynojet to see if they needed one, and was told they already had one. :tongue:

I'm down for a ride. There's another cat on here from Vegas. We should definitely meet up. :smile:

Where did you get your sprockets?

Thanks Tony, the bike looks great with that can!
I think a slip on gives us 1 placebo HP, because of the sound. :crazy:
By the way I just saw pictures from the TYGA full exhaust system on their facebook page.
I will order it as soon as it is available. :smile:
