I love my Linhai Aeolus 300.......but..  By  jonwaylee (Read 8,594 times)

The restrictions are on the 49cc scooters, anything larger does not have them. Those restrictions were to keep them from going faster than the law allows for non motorcycle class motorized bikes/mopeds and such.

What do you mean by "stuck"

The BMS260 I had, was fuel injected and could go 83MPH.
But it was fuel injected.
If you want to go faster, you could reduce back pressure by drilling holes in the rear of the muffler, or installing a performance exhaust for 250cc engines (usually an exhaust for 300+cc engines would work as well).
Doing so you may or may not gain 1MPH.
But to get more out of it... Try getting the right gasoline. Experiment with gasoline and engine oils and see what works best!

I think the intake is good enough. You're not changing a lot with the exhaust, just relieve the pressure in the muffler by increasing the exhaust tip diameter, or add more exhaust tips.

I have the same scooter and my speedometer gets stuck at 60 mph...I've passed traffic on a 65 mph. freeway, so I'm guessing I accelerated to around 70-75 with WOT on a slight downhill...on flat ground, mine would probably do 75 max.

Change from the vacuum fuel pump to an electrical one, I've had mine up to 77 GPS and I still had some throttle left over. The Vac pump has trouble delivering fuel at max throttle.

Well depending on your normal riding, I don't know if it is really productive. Adding one or two miles per hour on the top end, when it takes so long to get there and you don't want to run it at WOT all the time, I guess I don't see the point. Unless you are regularly running at 75 mph. On twelve inch wheels though I am not sure how much more I would want to go.

I only get mine on 2 mile stints on a 60 mph freeway and I have it at 70 sometimes for a portion of that to stay in a bubble of safety away from other cars. But for the most part I am at 60 or less all the time. I have had mine above and still pulling on a back country straight just to see what it would do, but after 80 mph, that was really enough for me, and my wheels are a tad larger. It is supposed to do mid nineties but I never want to try. The power is nice to have to get away from people if you need, but if you have to do eighty on a scooter with small wheels, you are better off just letting them pass.

Now, anyone trying to get more zip in around town on the low end, well, you can never have too much of that. But if high speeds is your thing, I would look for a more capable scoot with some cc's like a used Burgman or something.

But good luck with the project if you undertake one.
