Staying away from the "dark side"

[Tweak09]

I know most people in their need for speed they throw a big bore kit in their scoots. I know I did. Recently I threw my stock bore back in my Zuma. My mpg were suffering and I didn't want to get stuck with a ticket or worse, impounded.

So for the past few weeks I've been riding around on a stock bore with a leo vince zxr pipe and stage 6 goodies in the cvt. Two days ago my friend approaches me with a deal. A brand new Malossi 50cc Sport Kit for my stage 6 sport pro. I thought why not?

So I traded and installed it yesterday morning. Wow. I'm pretty impressed. I had a little trouble getting it in tune with the 82 and 84 jets I had but with the 84 and snorkel removed my plug chops look nice. Performance is good too.

Stock was about 40 with cruising around 35.
70cc was around 52 with cruising around low 40's.
Malossi kit about 45 but cruising around the same as the 70cc. Think I may be able to get more out of it with some cvt tuning.

For me this a great combo and works out great for my driving. With laws around here maybe changing I wanted to keep my zuma a 50cc. This was a good way to do it I think. Now I don't know the exact numbers with this kit compared to a stock bore or anything but I like it haha. Just wanted to share what I've come across since I don't see to many people talking about 50cc kits.

The kit I have is a little pricey but matched with the pipe and other goodies I don't see myself going back to the "dark side" haha. Cheers guys thanks for reading. Below is the kit I have and bad but recent pic of my zuma.

Thanks for the info! Ive been wondering about the 50cc kits and even thought about getting one to try at some point?. Good to know there is outta the box improvements to be had and still be 49cc.
Hows the mileage now?

there are plenty of guys who race 50cc on the track & strip so they do have potential!
i remember in the 80s there were kreidler 50s doing well over 100mph :0
bbk is the easy way to get more power and torque, but as a lot are finding, it doesnt always make your scoot faster...
and yeh, can get you in trouble with the law!

I did some moped mayhem team races about 20 years ago and the only rule is 50cc. some of the kits then were not bad and they still have scooter racing in the U.K. now which limits the capacity to 50cc. I would not think there is much difference in price though as they sell so many 70cc kits

even with just a bit of work and a squish band head you can realy wake up the stock bore

My mpg are in the high 70's to low 80's depending on how I'm driving. Where I'm riding also plays a role. Compared to my stock bore its about the same.

As for waking up the stock bore like jmk said. I could have done that yeah but this was traded to me. I didn't want to go back to the 70cc kit. So without my scooter being down for a week while I found the time to do the work and homework I was able to throw this kit in.

We had our normal meets at the church racing ours around cones in the parking lot today. I was surprised to be able to keep up with some of the other scoots there. My younger brother came with his video camera but were having issues with the sound/frame rate at the moment. Hopefully the video isn't ruined and I can finally post some video of the scoots racing. Brother bought a Vento Zip this morning! We have another scoot in the garage!
