Greetings all...Cycle ridder for many years '78 LTD 1000 and '83 HD Wide Glide. I recently purchased 2 Tao Tao Cy50 T3's for my boy's how are presently going to college at SEMO. One in, and joining Sig Tau Gamma fraternity ~ hence username of Sigtautaotao! I'm an infant to the scooter world, but have done allot of research to best select a scooter at a great price. I'm hopping that using a common engine like the 139 QMB long case will make it easier to obtain parts, and get sound advise from all the scooter rats roaming the streets!
Here is my plan to make improvements...please feel free to shoot holes in my plan!
1) put scooters together with the provided liquids, plus premium gas adding sta-bil (ethanol treatment) and run for 10-20 miles, return to garage and replace fluids to Castrol 4T 10w 40, Castrol Hypoy C 80w 90, and replacing the plug w NGK C7HSA.
After break-in 500 miles ish:
2) Check and remove any mfg restrictions, change the variator weights to 6-7g (I'm thinking oem is 8.5), change clutch springs to 1000 or 1500, rejet or replace the carb, replace air filter.

I'm not interested in giving my boy's screamers but provide a performing scooter that can take 2 uphill 15-25mph ish and 35-40mph on the flats. Whatever I do to the scooters, longevity is important to me...whatever they do to them (care and feeding) is solely on them.

So my questions are:
1) anything wrong with my intended setup or recommendations
2) are my mods and performance expectations reasonable
3) can any of you folks provide specific recommendations for cost effective sizes brands and necessary adjustments that will meet my needs...My son's needs v wants will be debated later!!

Respectfully....Scott
