Congrats on the scoot. Well the exhaust being closed up is a HUGE help. I believe ive sent you a message earlier about that. Changing it would be better but you can still get to 45 mph with that welded exhaust. Keeping the weights up above 7.5 Ive realized on the super 8 is a big deal. You can drop them and have crazy acceleration, but will lose a little bit on top end. The magic number for me , 2013 kymco super 8 , is 7.7 weights. I have a Naraku variator and a 15x12 mm Roller weight tuning kit with many different weights. Also a stiffer torque spring .. At this weight 7.7 I had the pushing power to climb over 40, but had 1/3 more acceleration than before. Also, getting your hands on a # 88 main jet would allow alittle better performance. Mine had a stock 82 in it. It was alright...85 worked better, but 88 was perfect. A good exhaust is going to be the BEST upgrade at end of day for your 2 stroke. Its already been cut and welded so its almost their, but any decent aftermarket exhaust will give you more power/speed... And noise. With great powerful exhaust comes great Whining noises. .. Also, opening up your cvt periodically and Lubing the drive boss and cleaning it produces instant performance upgrades if you feal your cvt getting sh**tier over time.
