Modern Buddy

Looking into making my buddy faster
its all stock rite now its a 125cc
what can I do

Please let me know suggestions
Or if theres parts you put on yours and how much faster did it go

Paint it green.

Haha funny suggestion but idk if green will do it thanks tho

Kit it to 161cc and change the gearing.

How much faster can you get with the 161cc kit and gearing

If you add decals, it can boost up the 125cc to 170cc's.

I think they racing stripes are only available for the 170i mods... That's why it's FI. Now you wonder why there are no stripes on the 125-150cc's

How many miles on it?
Best "mod" is to wait for 1500 miles.
That's when the motor really breaks-in.

What are the details on doing this? Estimated cost? Can anyone comment on their experience making the mods and with the results?

If I were to look into doing this my goal would be to get more speed off the line while maintaining the current top speeds. In other words I wouldn't be looking for faster maximum speeds, just for zippier acceleration and better climbing.

By faster do you mean off the line acceleration or at the top speed?

You can get better off the line acceleration with a performance variator, clutch, clutch spring and lighter weights/sliders.

Cheapest mod for the benefit: medium windshield. Modest boost in top end, on hills and better MPGs.

You want the 161 kit plus the bigger head. Not sure the larger gear set is available—yet.

For all modifications, results vary by rider, how it's installed, broken in, tuned, etc. (Engine needs to be broken in again with a kit.) But an increase of 5mph-10mph on the top end isn't unusual. A kitted 125 is faster than a stock 150.

After a cylinder kit and transmission upgrades, there are other modifications, but your value for the cost of parts and installation in exchange for performance really diminishes.

Do you want more MPH or do you want a quicker 0-60?

MPH:
Easy
heavier rollers/sliders (lowers rpms at a given speed)
performance CDI and coil (allows you to run at higher rpms)
performance variator (front pulley) (allows more belt travel, usually)
Moderate
airbox mod, upjet, performance pipe (more air + more gas = more power)
Hard
161 cylinder kit (more cc's yay!)
performance head (big valve or port and polished)

0-60 is basically the same, but
lighter rollers/sliders (more rpms at a given speed)
heavier clutch arm springs (increase the rpms where the clutch engages)
same as above

Thanks will look into it whats a good dealer to order parts off

+1 This. If it is not broken in do nothing until you're broken in @ +/- 1500 miles. Then reassess. You'll be surprised what a difference it makes.

I'd suggest starting with the transmission mods, then. Cheaper, easier and easier to maintain. Less long-term wear on your engine.

In fact, you might want to start experimenting with rollers/sliders for the stock variator. Roughly $30 a pop. You might get what you want with relatively little expense, though it's a trial-and-error process.

161cc kit is $184
Big valve head is $114
Installation will run you up to $350-$400 in labor, depending on your shop.

(Stage 2 kit is $429 and includes the cylinder kit, Prima pipe, clutch spring, rollers and three jets.)

NCY Transmission kit (variator, clutch, etc.) runs $224 and is fairly easy to install. Similar process to a transmission maintenance; much easier to DIY than the cylinder kit and tuning.

Dr. Pulley variator (only) is about $135.

Scooterworks doesn't carry this, so I just Googled it. But, yeah, comparison shop. I'm just ballparking here to give an idea of costs!

might wanna look a little harder Eric.

Thanks for the links, Eric!

Thanks guys gona start with a trans kit and see how I like it

Dr.pulley?
Or
Ncy?

the ncy is the whole transmission with out a belt
the dr pulley is just the front pulley, it doesn't have the back half
dr pulley does have a "HiT clutch", but it is $$$$ and only the clutch.

So ncy it is....
