I stopped by my scooter dealer and he told me he replaced the stock throttle body with one for a Jet Max a 250cc engine on his Glory , which is the same engine as mine , and installed an injector for a BMW 320i as it is similar Bosch design . He also has an open 250cc muffler , 14g sliders , custom grounded variator so that it opens up further and GPSed at 86 MPH 92 on the speedo .
I am saving my pennies for the parts and will see how it does for me

On my BMS 260 EFI the top speed was 83MPH on the speedo (Probably around 79-82MPH real life)

Ill have to look into getting an evidence 250 once I'm in Texas. This sounds awesome compared to the 150s

My 2010 Kymco Yager GT 200i (174.5 cc fuel-injected liquid-cooled) bike just hit a new top speed of 86 MPH the other day. I was getting a lot of looks from people as I buzzed past them on the freeway.
Hybrid ceramic bearings that were micro-polished and tungsten disulfide (WS2) coated in the wheels and rear gears, new taller rear gears (15% taller, spur gears... sounds like an RC car on crack) and a Pulstar HE1HT9 spark plug. And the "secret weapon" of LiquiMoly Ceratec to improve ring seal and give better compression. My engine started revving to the rev-limiter way too easily about 1000 miles into the Ceratec treatment. That's why I had to gear up... I got tired of modulating the throttle to stay away from the rev limiter when I knew the bike had more in it.
Once I get the new aerodynamic body finished and mounted, and get an infinitely variable transmission fitted to it, it should top out around 108 MPH... just once... riding a 12" rear tire / 13" front tire scooter at that speed will probably be about 30 MPH faster than I'm comfortable with. I'm not really looking for top-end speed, but for maximum fuel efficiency.

all my linhai 250 carbed scoots easily do 75+, and i usually buy them broken for under 300 dollars, and fix them cheap....of course i own a real motorcycle when i wanna go faster, cause scooter brakes don't exactly stop on a dime.

The brakes are one reason I went with the Aprilia Sport City 250 when they were on factory special at $2,999. Already fuel injected, same brakes as a 500cc bike with twin disks up front (stoppies are possible), 460lb carrying capacity, 15 inch rims and capable of  + mph per GPS. Add a Puig Sport Fairing adjusted for less wind resistance and you could find yourself hitting 100 on a level road. |
