Very nice bike!! Not a zuma 125 guy but is that an o2 sensor, exh temp sensor or both (because I two sensors in the exhaust stream)? Also the way the cylinder head(s) looks on that thing it looks like it has 2 cylinders, or is that DOHC single cylider or what? Im sorry for all the newb questions I know nothing about these 125's I usually dont wander into the 125 section but the 164cc title piqued my interest. Also last question.. What kinda speeds do you see on that thing? 164 has gotta be quite beastly.

I do have two O2 censors for now. Taking off stock over winter as It is one wire that hooks into my stand alone ecu system. I will use the Inovate O2 sensor to make all readings on the bike for next year. Once the winter weather lets up I will be making a new head and hooking it into a new muffler. I got to tell you about this little box of wonder though. http://www.rcscooters.com/_p/prd2/45693 ... hoedar-ecu

The hoedar-ecu is a USB hook up system you can run to your laptop https://www.facebook.com/HoedarEcu/?fref=ts

Shows you everything the bike is doing. records up to 2 hours ( riding logs ).

fuel / air readings, rpm range ( so you can tune the bike with numbers not guessing for rollers, torque spring, shims etc... )

is the coil working right? is the battery getting charged?... anything you want to know. Is the bike running hot?

You can set rpm limiter parameters to any rpm you desire ( F U governor!! I said 10,500k ) Its auto adjusts to cold weather to keep the bike at ideal fuel ranges. Set a fail save emergency mode ( if the bike block gets to hot it auto dumps fuel into the bike and cools off the block. )

It can be used for all motor sizes. I plan on jumping up to the 218cc in a year or so and this will keep the engine stable, healthy, and alive. Technology is crazy! zero guess work. Its all charted, measurable, and fail safe.

Took my tech guy about two sittings to get the bike prepped and running optimal. First setup was about 30 min to get everything set. I drove the bike, the tech dude checked out what the bike was saying through the logs and he made adjustments on my computer through (TeamViewer) a computer program that allows anyone, anywhere in the world to access to your computer and use the interface like they were right there.

I don't take the bike up over 70 because the gearing I have is set for lower end running but the get off the line, the power! it gets to 55 in half the time the 125 took. When I drop the 218cc in the bike I will put in some righteous 14/39 gearing to get it up to 100mph!!! It will do that kind of speed but I don't have a death wish, I dont think we have tires rated for over 90 mph lmao! Surprisingly the cvt setup ( if you get an aftermarket setup ) is the same no matter the change in cc's. Something to be said for the quality of the clutch parts in the bikes. (just got to put in stiffer torque springs) I have a 1200 rpm spring being sent as the 1500 spring is still a tad stiff for the 164cc but ideal for the 218 setup.

lastly, the two head covers? I think that's what you are saying? that's just how the head is for the 125 has rocker arms on either side of the head. then its got covers and since its air cooled i went with some perdy http://www.rcscooters.com/_p/prd2/24846 ... -heat-sink

take care. Hope any of this makes sense. :)

Bike is running like a beast. Now working on lightening up the bike bit by bit with carbon fiber items and cutting out un-needed metals and plastics. Replacing some metals with aluminum. May try my hand at some titanium metal work. will post pics of some of the carbon fiber items I am working on in a few.

Post Re: 164cc zuma
So I did my first carbon fiber skinning of some parts for my bike. They turned out rather nice. They arn't perfect but I learned a ton on how to skin. I shall post more parts as I skin them to. Want to start working with kevlar.

What do you mean by "skinning" ? Did you hydro-dip/water print these panels? They look like they cam out really well. Front fender looks sick!

you put carbon fiber fabric over the fiberglass parts and then clear coat them.

Post Re: 164cc zuma
Please do not take this wrong...

Why a Zuma 125? Why a scooter?

I think I understand, but I just wanted to ask, to see your point of view and thoughts.

Anyone else doing hop ups and trick stuff feel free to comment. It isn't negative, it is purely your point of view.

Ok. So you made a fiberglass mold for the parts or did you just wrap over the plastic parts? Does it work like that. Looks really good!

As far as why someone would do this to a scooter, I fully support the addition of carbon fiber parts. The carbon bug bit me years ago and I have multiple parts. It's all about making your zuma your own with whatever parts you wanna run!

Looks like the real stuff there.

Your second answer... why the scooter? A curious question, I know any answer given is totally legitimate. I'm just curious. Heck, we were trying to hop up MB5 Hondas back in 84.

Looks really good. Much lighter? Did you actually weigh them?
