I need a few more miles per hour!

Tell me why. I see where people modify 50ccs to go 50 or so, but I am told that My 150cc modified to the bone can only go 50-55. I can already go 60 without any mods. Don't make sense to me. I will try the tire first, that sounds reasonable and the kind of answer I was looking for.

If your 150cc is a taotao, then where the number 60 is, is actually 55MPH GPS verified.
I got confused there too.

I took my bee-hach out on a ride tailgating a truck and got upto 65MPH, with the engine cutting out at 9,100 RPM (or something; false contact, or rev limited?)
Once away from the truck, my speed dropped back to 8k RPM, or 60MPH.
I may try to get heavier sliders again, to get that top speed at 7,5k RPM again, but those sliders usually don't last long. you either overgear the bike, so it can run well for a few months, or you gear the bike right, but as soon as the sliders/rollers wear out, it over revs again (usually in a few months of riding).

I'm actually thinking I should check up on my stock belt, before it breaks.

Because the non-BBk'ed 50's DON'T go 50mph! Hell, even a fully modded BBK'ed to 83cc doesn't do 50mph. People serious have no idea. Many times I have seen other 150ccs, and EVERY rider says they "easily do 75-80mph" because they take what their speedo says as fact.

My bike has FULL mods save for a BBK, and it does 65mph on the flats as per GPS. Lighter bikes (mine is a type-23 style) may go 1 to5 mph faster with mods, but no stock gy6 can even touch me.

One of my club members swears his type-04 (handsome boy) 50cc with BBK and full mods does 70 mph (like SWEARS!) and even our old beater type-04 150cc smokes his bike.

Most mods WILL NOT increase your top speed, they just increase acceleration to THE SAME top speed it had stock.

A stock 150cc gy6 w 13" wheels goes 50 to 55mph top speed. You can tune it out to about 60mph with careful mods.

As for what to do; read my sig, and do those mods, you'll get the same results. Don't listen to people about bigger carbs, as bigger than 24mm are simply over-carbed and aren't making more power, just running rich and wasting fuel. A gy6 157qmj likes 24mm w 105 to 115 main jet, any more is way too much.

Sorry I should clarify:

no 50cc 4t engine is that fast, 50cc 2t, well that's a whole different game. My 2002 Kymco Yup 50 2t has been gpsed at 51mph.

Also; Spectre is balls-out modded :P
