Isn't it scary going that fast on the Buddy 50 though? Maybe it's the 10-inch wheels but it gets a little too-shaky-for-comfort around the 40mph area for me. You? It doesn't really feel so shaky. I feel more comfortable on it then my motorized bike going 35mph. The suspension is stiffer then I'd pr...

Have you left the 3 small clutch springs alone? On my Yamaha, that is where I get the most bang off the line. Stock springs are 750. I put 1k in the 3 small springs, and add a stage6 soft for the contra spring. The stage6 is about 125rpm increase over stock. My 50cc didn't have enough grunt to make...

Re: Pulling cylinder without pulling the motor on a Buddy 12

Last year I did a 161 BBK when I had the bike entirely apart with the motor out. Since then I got a NCY big valve cylinder head that I want to try but haven't gotten around to install it yet. I will have to pull the cylinder because the big valve head uses thinner base gaskets. If anyone has done a...

Did you take the whole scooter to the repair shop or just the carb? Did they change the jetting? If it had run fine previously, I wouldn't change any jetting, I'd look for some sort of dirt causing clogs. Maybe check to see if the fuel filter is clogged or just look for some particles in the carb bo...

You can also buy something like the Trailtech Vapor which not only allows you to calibrate the speed based on wheel size, but also has a tachometer and temp sensor.

I want one! The big issue is unless you go with naked bars on a Buddy, there aren't many good spots to mount it.

New Update: I installed a 1000RPM contra spring in the clutch. I was having an issue where when I would go over a rolling hill or come out of a rolling turn, the CVT didn't downshift and acceleration wasn't so good. Specifically, on my way home from work, there is a big uphill with stoplights and lo...

I finally got to compare my modded 50cc to my friends 125cc Buddy. The 125 is mostly stock, but the owner changed the carb and he said it “picked it up� quite a bit. So... Off the line, my Buddy will take it by a good amount. On the hills and at the top end, the 125 has the edge. I’m going to ...

So... I removed the snorkel from the airbox. It did favorably balance the air/fuel ratio at different throttle positions. I was also able to upjet to a 92 jet and hit 51MPH on my slight uphill jetting run. I'm pretty sure this is a 55MPH+ scoot at the moment, but need to confirm on some strait flats...

What did you upjet to? And/or bigger carb and what jetting? If you still on the stock carb and jets with a Malossi 70cc (cast or aluminum) prepare for a seize! Just putting that out there..... When I installed the 70cc BBK, I upjetted to an 88 from the stock 75. The proper range for me was about 85...

This exhaust is really going to increase my acceleration and top end, but I need stronger clutch springs. My clutch currently engages at 4500RPM and the Malossi 70cc + Yasuni R exhaust just don't make power there. It seems like the power kicks in at around 6000RPM. So I have some new clutch springs ...

For anyone going through this...

I got the Yasuni R exhaust. The bracket mount holes had to be ellngated. A drill and dremel took care of it. Exhaust 90% installed. Dodging thunderstorms as I install the muffler.

Will report performance gains when the rain stops and I get it dialed in(jetted).

Buddy 50... Exhaust Pair Delete?

When upgrading the exhaust on the Buddy 50, do you need to plug the hole coming from the motor that goes to the exhaust valve?

I'm thinking I'll use a short hose with a plug, but not sure if there's a better method.

Is it a pair system?

Buddy 50 Carb... No Needle Clip?

I have a hesitation at 1/4 to 1/2 throttle. I went to change the needle position and it turns out there is no needle clip. Is this the way it is with the stock Buddy carb? How about the aftermarket Keihin carb? Does that have a needle clip?

From my research, the original law said there was a 4% range, from -2% to +2%. That was changed to the same 4%, but the range was from -1% to +3%.

It probably also protects manufacturers from underreporting speed when accounting for tire changes, wear or even differences between model options.

Aftermarket speedometer

My Buddy speedo is more accurate then my Tao Tao, but I always thought there would be a market for an aftermarket speedometer face. All someone has to do is reprint the face moving the mph and kph locations down 5-10%. I don’t know how hard it is to get inside the gauge, but it could solve the iss...

What kind of exhaust are you trying to put on? I put on a Yasuni Z with silencer but also replaced the cylinder. It came with a few different brackets which fit for the most part - had to do a little moving around. I will be replacing the cylinder before I get the exhaust. Malossi 70cc on its way. ...
