2000 Honda Dio SK50

Hello,

I've got a 2000 Dio SK50, and planning to install a Polini 72cc Contesta kit. I was also thinking 9:1 gears.

Do I need a new carb, or can i adjust the stock carb?

Is there anything else that I need to upgrade to optimize this setup?

Thanks

Okay, so I've established that a bigger cylinder will go a long way. I'm comtemplating between the Polini and a Taiwanese product. I also realize I'll need a new carb to make this work. If I go with a 72cc, will a 19mm carb work well?

Where is the best (and most reasonably priced) place to order parts?

I've seen some 125cc kits, but I believe I'll need to change the crank for this too.

I'm really trying to spend as little as possible on a reliable setup that will give me better speed to keep up with traffic in Toronto.

I would appreciate any help here guys.

Thanks

Well, if you're just trying to get a little more 'oomph' out of it, you can get away with just changing the cylinder and the carburetor. The 19mm carb should work just fine with your engine. Any more than that, and I believe it won't be as effective because of the inlet manifold on your scooter. The inside diameter of the manifold is around 19 or 20mm so a larger carb wouldn't benefit you too much.

If you're keeping the stock exhaust, you're not going to need to tinker too terribly much with your roller weights and drivetrain, although the setup from the factory is usually not optimal for everyone. You may want to play with your rollers just a bit regardless. Usually, you'll need lighter weights.

With just the cylinder and the carb, you should notice a substantial difference in performance all the way around! If you want to give it a little more you could always get an aftermarket filter, exhaust, clutch, torque driver and all the other goodies. For street use though, I'd keep the stock exhaust and airbox and stick with just the carb and cylinder.

As far as places to order from, I can't really say because I don't know if United States prices are better for you than Canadian ones. There's some kind of "Scooter Underground" in Victoria, don't know much about them really... Scooter works in Chicago IL (USA) is closer to you than most places in the States, so you might check them out. They have a few nice cylinder kits, and can order anything they don't have from Malossi. Many people order from scooter-attack and scooter-center, even though they're "over the pond".

Hope this helps a little.
