Hey scooter, are there any changes I could make to increase the speed, and keep acceleration? I don't want a race bike, just a little increase in speed for the commute to work. I do not want anything drastic like bore kits, just get a little better speed for the commute so I don't hold up others on the road.

A good variator will give you what you are looking for. OEM transmissions are set up for emissions standards, to meet both noise and pollution levels, and a aftermarket variator will optimize the power band to full potential. Again, I noted "good" variator, as all aftermarket performance variators are not created equal. From my experience, TST makes junk, Polini works but hard to tune, Malossi works great but roller weight choice is important, Naraku is nice for the money, NCY makes nice package deal kits for a fair price-comes with a variator and torque driver, J.Costa is just weird. So, pick wisely and enjoy. For variator removal you will need fixed face locking tool or strap wrench to hold it (use a impact gun at your OWN RISK-not recommended!), socket for the nut, and a torque wrench for reassembly (rent/borrow from auto parts store). You Tube will be your friend for how-to videos. So you bought the Jonway? Get a good price? Year and miles?

Thanks, I definitely want the best parts, as I learned a long time ago that it is better to invest to fix and repair any vehicle properly as it saves a great deal of time, money and future problems.

ScOOter, I was just looking at the nyc kit on Amazon, and like what it says, thanks again, but I have one more question. I know that increasing speed will usually affect the fuel mileage, and am willing to accept a second for the extra power. I am just curious about how much of a decline should I expect, and what should the speed increase average? If need be, I am willing to invest in a larger fuel tank.

Your scoot should get around 75-85 miles to the gallon in the real world, and you may loose a whopping 2 mpg's overall. Just variator, your top end speed will increase around 2-5mph (again, the scoot will only go as fast as the final drive gear ratio) but, when tuned right, will move off the line. If you get the whole NCY kit (variator and rear pulley) maybe 5-8mph extra and even quicker off the line. Trust me, its worth the upgrade! Also, larger tanks are not always worth the trouble. Oh, and make sure if its the whole kit (vario and rear pulley) that it keeps the electric starter if thats an issue for you. Some over-range kits have you remove it, some dont. Not sure exactly what NCY kit your looking at, but their tans kits are good. Finally, if your thinking of changing the final gear ratio, make sure your motor can move it! If you dont have enough power to turn the "improved" ratio the scoot will actually be slower. Final drive mods usually mean a bbk.

I am looking at the complete kit, it is 205 on Amazon. It has everything, that I made certain.

I just Installed the Amazon NCY Variator kit yesterday...BUY IT!

My kit came w 1000lb clutch spring, 10g rollers... my stock gray color rollers were 12.7g worn.
I just ordered Dr Pulley 13.5 Sliders for my 190lb weight, on a little 150cc Tao Tao VIP GY6 157QMJ... the 10g NCY rollers were good to 1/2 throttle, but a bit revvy for flat WPB roads.
I feel my motor can turn a higher gearing. I am wanting a powerband from 1/4 - 3/4 throttle and the 10g rollers I thought would do it better, I feel like its revving out too much or I need a taller gearing. FWIW my scoot is tuned well. Perhaps a lighter clutch bell than NCY next, and a yellow 1500 clutch spring.
I did change my internal 3 clutch engage springs from the red NCY, to my stock springs that engage the clutch at about 1000rpm, which is handy for ultra slow riding smooth.
---------------
Update: The Dr Pulley 13.5g Sliders are just a tad too tall a gear, it pulls bit better low/mid, mid-3/4 'just' struggling to accel, 3/4- full 'slowly' winding out, for general tall gear cruzing its nice. I concur with some reports out there that the 12g sliders would be 'perfect'
