[SLESTAK75]

Welcome Greenmachine. I have this same buggy and I agree that out of the box its not the most impressive. With some bolt ons and a little work I have become pretty impressed with it. It is among the heaviest of 150s which makes it ride nice. Opening up the intake and exhaust, adding a ported and polished and milled big valve head, and an A-12 cam, along with rejetting the carb to match to new flow has made a tremendous difference on mine. I can only imagine it with a big bore. Check out the thread "most common mods for gy6 150". It has lots of details on pulling more performance out of these buggies. It is not a 350cc but dont give up on the lowly 150. It can be impressive. Mine has pulled this heavy buggy and me (nearly 200#) and my dad (180) up a long steep hill at around 22mph. Before my mods it pulled me alone up a short steep hill and slowed to nearly 10mph after hitting the bottom at near full speed. The hill I pulled with my dad was hit from a cul de sac at the bottom accelerating up the hill. Check that thread and as always, if you have questions just ask.
