Upping the displacement will push you through the wall of wind . Every 10 mph requires almost 50 % more horsepower to overcome wind resistance . 65 mph is going to require a very high degree of tuning .
The beauty of a cvt is you can set it to where the cylinder makes the most power so when you change gear ratio as long as you go up within 20 % of where you are your 0-30 time will be in the same range .
52 for 150 you might be able to pick up 5 miles per hour just getting a sport variator like the ncy simply because it will give you a higher gear ratio .
The compression spring might not even be needed over your current spring until you up the power .

Well I went with the NCY New Generation trans kit, 12g rollers, 14/37 gears, Stock exhaust, stock intake for now, the NCY 61 mm bbk with head and the A9 cam. Removed the pair system. Took it around the block and so far it's running great. Seems to have more acceleration even with the higher gears and top end is higher. Stock gauge read 65 and wasn't done yet (Yes I know it's WAY off). I will get a GPS top end as soon as I get a few miles on it.
Hold off on the big valve head and carb. Higher velocity thru them gives rewards at low and medium rpm. Port matching and smoothing carb to valve helps as does opening up restrictions in air flow to and from the stock airbox.
