When to mod a new scoot?  By  Deleted (Read 949 times)

I mod mine before the scoot has 5 miles pull the motor out and all

I'm of a different state of mind. I'd ride it stock, until parts wear out, and only then change them with better parts, when needed.

I only would put a BBK on it, when needed; change the performance variator when needed, or change the belt, when needed.

If it's doing just fine stock, I'd ride it stock. No reason to spend money on a bbk, if the other parts like belt etc are only going to wear out faster that way, and when you don't really need it because the scoot works just fine in traffic.

For instance, in city traffic I would put a BBK on a 50cc, unless if the stock (4T) 50cc is modded to the bone, otherwise, a 50cc just doesn't have enough power to plow through traffic IMHO.
A 72-75cc does. Especially if the variator is tuned, or it has gears!

If I have a 150cc scoot, I'd never change anything on it, unless I'm taking it on the highway more than usual. Perhaps mod it for better gas mileage in the city. For me a 150cc is good for very heavy people to move through city traffic just fine, or for 2 x 200LBS people to travel together in the city just fine.
For one skinny person like me, most 150s have too much torque anyway.

I see modding scooters as making them more functional for the purpose I need it to do. Meaning making them more economic in my situation, meaning putting heavier rollers in, getting better gas mileage, and replacing belt only; unless something is really working bad from the factory and needs replacement.

If RPMs stick to ~6k RPM the rollers/sliders are probably optimized for performance.
You could tune them to go ~7500RPM, but then you'll use more gas, wear the engine faster, and when you accel at wot, the engine might surpass 8500 RPM.

BBK= Big Bore Kit.
